Some even request that I print the chapters for them (which I do.). That might be true in a sense, but relative to next generation, high throughput techniques, it is a very small portion of the sequencing actually happening in this day and age. Pinacocytes are epithelial-like cells, form the outermost layer of sponges, and enclose a jelly-like substance called mesohyl. In some cases, it appears that the authors do not fully understand them. citation tool such as, Authors: Mary Ann Clark, Matthew Douglas, Jung Choi. I think this book is comprehensive for a general biology textbook, but it lacks some depth and breath for some concepts. There are a few areas that I am pleasantly surprised by the detail included, but other areas where I am a little surprised to see detail lacking. In Fig 5.11 the diagram depicting osmosis is misleading due to the depiction of the height of water following its movement across the membrane. "Connection" sections (except for "Art") were for the most part excellent and bridged concepts with real-world issues. I have used chapter 1-16 of this book for a 100-level community college class "Integrated Chemistry and Cellular Biology for Healthcare Professionals". While it is challenging to cover all Biology content in an introductory text, the book is an excellent substitute for the previous Biology text we were using. However, The themes of epigenetics, genomic research, non-coding RNA, and CRISPR-Cas gene editing were not discussed and need to be perhaps added on with additional course materials. It feels up to date; there is a link to an online genome browser, for example. The placement of the chapter within the larger text makes sense, following a section on the introduction to metabolism, and preceding a section on photosynthesis. Its generally well-written. Furthermore, an instructor can edit the text for their own student population and according to their unique needs. This error appears to be due to a change in the figure from the first edition which was not accompanied by a corresponding change to the caption.) Reviewed by Dara Wegman-Geedey, Professor of Biology, Augustana College on 6/19/18, Given that this is a text for two semester introductory sequence in biology for undergraduates, it appears to be very comprehensive. Not sure this is a major hang up, just something I noticed. The type of logical thinking that uses related observations to arrive at a general conclusion is called ________. Finally, each chapter has review questions, both multiple choice and short answer (critical thinking). Blocks of text are broken frequently by diagrams and questions, which helps them feel less intimidating. The text is not culturally insensitive, and material can easily be supplemented with current news articles and essays addressing the moral and ethical implications of current findings and technologies. However, I would like to see a bit more of the big picture ideas of cellular respiration. It is provides a baseline for the essential content for a Biology course. This review is based on close examination and reading of all or sections of 27 chapters (1,4, 7, 8, 10, 11, 12, 14, 15, 18, 19, 20, 22, 23, 24, 25, 26, 27, 28, 29, 32, 33, 43, 44, 45, 46, and 47). Overall, this book provides a mostly adequate resource for teachers who are trying to save on textbook costs. As no comprehensive textbook like this is ever completely error-free despite the best of intentions, I am sure there are some inadvertent mistakes. While the overall clarity is good, the use of jargon in places could be confusing to students. This is a good book for an introductory level class, covering all material that would traditionally be presented in a one or two semester series. With failing vision reading from a standard text book requires good lighting and magnification. Numerous other ways of logically organizing chapters are certainly possible, but that employed in this text flow nicely. Joint and body movement illustrations and descriptions are very detailed Note: I have not yet used this book in a class. The index and glossary are fine. It also makes it easier for a student to be able to navigate through the text and find a particular idea or piece of information that they may be searching for. Show more water molecules in shell of hydration image fig. I like that the chapters are fairly short. Career Connections are great throughout, but some appear to be written from an American perspective. This is a very comprehensive textbook that provides an appropriate balance between the different fields of biology. These are helpful in linking the topics covered to real world issues. It was easy to navigate the contents list, and very easy to switch from one section to another. The only part of the text that could be offensive are in the links to the advertisements that are part of the videos links to concepts covered in the text. Each carbon atom can bond with as many as________ other atom(s) or molecule(s). However, there is not enough explanation or detail provided for most students to make any sort of meaningful connection. How many grams and how many liters of water would have to be evaporated through perspiration to rid the body of the heat generated during two hours of exercise? Weballosteric inhibition. hi, i am a student and i have been using your reading guides to help me with my reading assignments for this book and they have been extremely helpful! The flow and organization is comparable to other texts in the market. The information provided is up to date and comparable to similar texts. These are students with majors and interests that include biology, biochemistry, neuroscience, kinesiology, environmental science, and pre-professional students who aspire to attend professional graduate programs in medicine, veterinary medicine, dentistry, and allied health care. Figures rendered well. The coloration of these figures should also be improved for contrast. Content-wise, Biology -2e very closely aligns itself with most traditional introductory Biology text books. The contrast of the colors is too strong which detracts the reader from the content. As with other textbooks I have used in the past, students do not read chapters unless you give them some kind of assignment that goes with it. Typo in bicarbonate image in Ch.2 Both online and .pdf versions have links embedded in the Table of Contents, making it easy to skip around through the book as needed. The target audience is of a generation that grew up with the internet, Youtube and social media. I did not notice any obvious internal inconsistencies in framework or use of terminology. The short video is correctly labeled as dispersion in Wikipedia rather than as diffusion. Chapters seem to be accurate, and there does not seem to be any significant bias in the content. I found the information presented in this book to be accurate, up-to-date, and consistent with the most widely held scientific opinions on the topics. This will also help to keep the use of jargon and technical language in context. I found chapters and subheadings on nearly every topic that I expected to see in a biology text for majors. read more. The chapter sections are well defined and accurately titled. WebTotal Pages Answer Key N/A. I'ld like to see some deeper discussions into current topics such as CRISPR and other Biotechnology related concepts, although discussions around genomics was sufficient. Depending on your choice, you can also buy our Tata Tea Bags. Section 19.1 Link to Learning online calculator is a useful tool but it would be nice to have an animation illustrate the principle of HWE (similar to the Link to Learning on Drift in Section 19.2). It is the opinion of this reviewer that these differences in writing styles are not a hindrance to learning rather an opportunity to prepare students for the real world. Teaching earth science for the first time. Web resources have a notoriously short longevity and links to external sources need updating, so their inclusion makes regular updating essential if only for that reason. Do you have a earthscience corner? It may remain as a heuristic that is often mentioned, so perhaps there is still some use in having in a textbook, but its not exactly an up-to-date framework. read more. read more. glycosidic bond. I noted several examples in which material is explained clearly in one part of the text, with inaccurate or inconsistent information in other places. The second-weakest section for my course is on developmental biology, and there are some other texts that offer more (e.g., on polarity genes, segmentation genes, and hox genes). A few differences I would like to highlight. it could be conveyed that it notes ALL species variation is directly related to genetics). The chapter appears confused about how time is represented in phylogenetic trees, saying both that trees do and do not have a time axis. I have tried to obtain a paper copy of the textbook, but it is not as easy as calling my publisher for a desk copy. Would seem to be easily digestible for an early-career college student. However, I now realize that instructors are encouraged to cut irrelevant material and use relevant material to their coursework. The Figures in the textbook are also generally accurate. The online format should make it easy to update.There are no peer reviewed references for each chapter so there is no way to know that the material is scientifically accurate. 1171-2 are covered with weakly explained equations and values in mm Hg. The text is easy to read and flows nicely. Images and figures need revision as many are displaying with poor resolution in the pdf version. It also is relatively current, and includes some relatively recent knowledge, but the time for a major update is approaching. While there are probably a few more grammatical errors than would be typical for a traditional textbook, I have no problems with the grammar of the text. read more. This is a laudable grade for the first iteration of an enormous community project. The contents list expands readily, and the names of the chapters mirrors those in the competitor texts. I saw very few references to race/ethnicity in the text, Reviewed by Thomas Giardina, Assistant Professor, University of Delaware on 5/21/18, This review will focuses specifically on a representative chapterin this case, Chapter 7: Cellular Respiration. Even though simple, I like the illustrations in this textbook because they are clear, to the point. Key words in bold are also easily visible and defined at the end of the chapter, so students can quickly find definitions. Just go through our Coffee Vending Machines Noida collection. I prefer to have more evolution covered in the first 2 chapters but it is just as easy to jump to chapter 19 to harvest enough info to inform the rest of the cell biology chapters. In the pdf version there were also many blank sections and pages. More review and recall of key terminology and concepts should be provided in each chapter. Furthermore, There is one image of a white woman scientist and there are two dark-complexioned individuals with skin conditions. In Chapter 8, the text states, The energy extracted today by the burning of coal and petroleum products represents sunlight energy captured and stored by photosynthesis almost 200 million years ago. No, fossil fuels formed in the Paleozoic, which ended 252 mya. However, because of the errors and the use of terms that no longer apply, students may become easily confused and this could affect the longevity of the text. The writing is clear and makes good use of figures and images. I know that I have such students, and I know that this text would be hurtful to them. Within each section, subheadings are used effectively to break-up and organize material. read more. The text is visually appealing; section titles and sub-section titles are easy to see (green text). Which of the following sciences is not considered a natural science? This book is perfectly appropriate for all readers. Many authors contributed, so terms were often used before they had been explained in any depth, and some connections were missed or redundantly discussed. It covered all of the subject areas that my current General Biology textbook covers. Professor, Science Dept. Figure 3.32 is not helpful and does not show H-bonding or antiparallel arrangement clearly. Biologists refer to this fit as adaptation, and it is a consequence of evolution by 2 Review Questions - Biology 2e | OpenStax Review Questions Review Questions Highlights 4. Some chapters were confusing when there were brief intros to some clades, then human A&P, and then more animal systems. ", Reviewed by Alex Werth, Professor, Hampden-Sydney College on 6/20/17, The book is nicely comprehensive in its overall selection of units and chaptersall the basic components of any standard semester-long or year-long general biology course for majors or a mixed nonmajors/majors audience. I did not see any grammatical issues while skimming the text. Tunicates and vertebrates are sister taxa that diverged more recently. I can focus on the sections I need, and they seem to stand alone without needing references to others. Sections should be revised to ensure figures link closely to text content and do well in demonstrating important concepts. As a result, she determines that plants grow better when exposed to music. The genetics section of this book appears to be consistent. If there are provisions for regular revisions of the textbook these issues can be addressed easily. One critique is that the learning outcomes at the beginning of the chapter and the visual connection and review questions at the end of the chapter are mostly lower order cognitive skill questions (i.e. Figure legends were descriptive. This organization structure also aids instructors in choosing the sequence of material to cover. The chapter-end questions, the opening outlines, and other such framing devices are used consistently throughout the book. Sample answer: Gatorade contains water, sugar, dextrose, citric acid, salt, sodium chloride, monopotassium phosphate, and sucrose acetate isobutyrate. It would then fall on the instructor to really add a lot of depth and context for the content into their class in lectures and active learning activities. On page 285, the text states, Cells in G0 phase are not actively preparing to divide. Each chapter includes at least one link to an external resource. Overall this text covers each topic in adequate detail and provides enough detail and content for a two semester coverage of biology for majors, especially if this text is used alongside additional instructor input and labs. It provides the student with a strong foundation with which to analyze and respond to new knowledge and apply it in the contemporary world. First, the visual portrayals: The vast majority of working scientists shown in photographs appear to be light-skinned, and mostly male-presenting. The open access nature of the content means that figures and illustrations are readily available online, making it easier for instructors to access the supporting content and incorporate it into their own teaching materials (the book also comes with all the standard instructor resources), and for students to directly interface with other online media (for example, embedded YouTube videos). This textbook was comprehensively organized and populated with topics. The book takes a historical approach to dealing with protists and is, in that respect, in need of modernization. More importantly, however, rapid advances are made in many aspects of modern biology, most notably in molecular genetics, but even other areas are undergoing change from the application of molecular approaches and new discoveries. My classes are full of women. The topics are arranged in a typically progression and build on one another in a traditional fashion. As mentioned above, changes in our understanding of biology are happening quickly, but those can be incorporated into the the framework of this textbook in a straightforward way. Also, the glossary has terms that are not fully defined. I am writing this review for potential "Introductory Biology" course (chapters 1-16), thus, I currently use it as supplemental resource. I think the book is of equal quality, scientific rigor, and depth as any mainstream introductory biology textbook currently on the market. I did not find anything culturally insensitive. Either way, the machines that we have rented are not going to fail you. For example 14.3, a dead mouse image was unhelpful in understanding this classic experiment. Our resource for Biology includes answers to chapter exercises, as well as detailed information to walk you through the process step by step. On page 496, the explanation of punctuated equilibrium is very weak. The text is relatively up-to-date, certainly adequately so. To submit a correction, 1. I was expecting to see basic cellular biology and a survey of organismal diversity including units on evolutionary Lots of options are provided for accessibility. Would it be possible to move the image credits to an Appendix at the end of the text? read more. The illustrations were also very helpful and I can see them providing a lot of help to those visual learners. They should be discussed along with cytokines. So it will remain relevant for the long term, as general biology subjects do not change very much anymore. For a majors, there might be some supplemental material required, if the instructor wants to dig into particularly new technologies. The chemistry of life and macromolecules in biology have to be discussed before gene regulation which itself has to precede the various organ systems. The ads might indicate endorsement by a faculty or school for certain corporations for example. Managed to relate content between the chapters and provided an evolutionary context to the topics. This helps students connect what they are learning with their lives. I honestly do not think that the author has a clear understanding of this important topic. I was happy to see that the text includes the relatively new supergroup taxa presented in Chapter 23 when Protists are the first eucaryotes discussed, but I'd like to see the supergroup concept reinforced at the beginning of the chapters on Fungi, Plants, Invertebrates, and Vertebrates. (a) element; (b) element; (c) compound; (d) mixture; (e) compound; (f) compound; (g) compound; (h) mixture. This will probably be apparent especially in the molecular genetics topics. The Table of contents is easy to access (always on the top navigation bar) and so with a click a student go right to the assigned chapter or section. Some analogies used to make a point were dull and unintelligent. The content of the text is generally accurate but not uniformly. I did not find any inaccuracies or errors in my review of this textbook. Specifically stating which pages the specific answers could be found would be even better. Having said that, I need to add that a major complaint I have of the most widely used introductory textbooks for Biology majors is that too much attention is focused on trying to provide that context, which makes the essential facts more difficult for some students to grasp. Often these links provide cutting edge insight into both the research and application to make the However, the blanket statement as written by the authors instead plays to the very common misconception that genes are all-powerful and determine ones fate. Reviewed by Shalini Upadhyaya, Associate Professor , Reynolds Community College on 2/8/17, After having used the book for majors biology course for the last 4 semester, I have pleased to say that I content is simple yet efficient and effective. In fact, I would argue that a strength of digital textbooks is the ability to quickly zip from one section to another with a click. The contents list expands readily, and the names of the chapters mirrors those in the competitor texts. These have all been a work in progress. All topics are covered appropriately. Broadly speaking, the TOC and units are easy to navigate and the images/videos are placed appropriately. I had a few problems with the textbook interface while reading it on Adobe Acrobat reader. I never came across anything that looked culturally offensive to this white guy. Authors also do a great job of explaining complex ideas through case studies, diagrams, and videos. Biology (OpenStax) is as comprehensive as, and follows the general topical format of a commercially available introductory biology textbook designed for life science majors. One surprisingly omission in this section is the lack of total ATP yield from oxidative phosphorylation. Reviewed by Jessalyn Sabin, Instructor, Hibbing Community College on 6/10/15, This textbook was comprehensively organized and populated with topics. The glossary appears comprehensive, however, many duplicates (ie. The text is up to date and addresses relevant and contemporary issues. Which of the following sequences represents the hierarchy of biological organization from the most inclusive to the least complex level? The organization and flow of the text is logical and straightforward. Further, some comprehension questions at the end of chapters would continue on the next page making it hard to understand what the answer choices were. The Given that this is a text for two semester introductory sequence in biology for undergraduates, it appears to be very comprehensive. CRISPR-CAS technology is sufficiently explained for an understanding of the concept without going into too much detail. The chapters are organized into 8 main units. Instead, climate change is dealt with separately. On page 54, this sentence requires a fuller explanation: Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol. That said, I found no problems with the text interface. Many times, a new term is used, but there is no definition or introduction of it. The book has links to external digital content at OpenStax but some of the QR codes and/or URL do not seem to function. read more. organisms with simple diffusion through countercurrent flow) and then using human systems as examples. I enjoyed that throughout the chapter, there were little blurbs relating the material being discussed to a potential experiment, a human disease, or thought questions. This book will serve the purpose of introductory biology and could very well be used in place of the expensive textbooks. It has a good online index that is searchable. I thought the explanations were very specific and well versed. I have not found any errors within the text. Images are simple and clear. I was pleasantly surprised at how interesting and easy this book was to read. This text ties together conceptual understand and application to the real-world in a way that I feel will benefit many first year Biology students. The table of contents is not available on each page, so navigation other than directly forward or backward is difficult. In truth, both fields are equally rigorous and important, they just study different parts of our world. 1 Review Questions - Biology 2e | OpenStax 4. It is possible to see the resolution of every correction suggested over the entire history of the book when it was initially published in 2012 at: https://www.openstaxcollege.org/textbooks/biology/errata. I had no issues browsing and reading the textbook. Diversity of life and physiology get a lot of attention and surprising detail for an introductory textbook. I am optimistic that this book will be quite useful for me and my students. Historical aspects are important so the students recognize and understand scientific pursuits and can be inspired. Overall, this book covers the essentials required by an introductory biology textbook. In another example, 7.11 and 7.12 both refer to pH gradients across the mitochondrial membrane. The graphics are fewer and lower quality compared to expensive conventional textbooks, and the study questions are fewer and less thoughtful--an expected and acceptable trade-off given that this book has the potential to save students hundreds of dollars. They are generally uniform in length, although some subsections are longer or shorter than others depending on the topic. There is not much to say here. The text describes the reactions in steps, but they are not accompanied by labels on the figure, which I think is a shame. Pinacocytes are epithelial-like cells, form the outermost layer of sponges, and enclose a jelly-like substance called mesohyl. The text appears to be culturally sensitive, but there are not very many examples of the importance of biodiversity to a variety of groups of people across the globe. OpenStax Reading Guides. On page 749, the text says, In the following Cenozoic Era, mammals radiated into terrestrial and aquatic niches once occupied by dinosaurs. No, the aquatic reptiles of the Mesozoic were not dinosaurs. On page 807, the text states, Based on molecular analysis, vertebrates appear to be more closely related to lancelets (cephalochordates) than to tunicates (urochordates) among the invertebrate chordates. This text is culturally accessible and inclusive. The figures have a hyperlink in the text that the student can click on. I found it had enough depth for a majors course while being accessible for non-majors. Students can download this text for free, view it on their devices and print it out. It would make more sense to discuss the topics as they arise than to briefly mention and revisit later. Generally, having so many possible ways to access the material makes the interface exceptionally positive for students. Every link that I clicked on was active. The questions at the end of sections are helpful to student learning. The interface was fine. Complete the following page as thoroughly as possible. In this regard, there is very little room for innovation or variation from standard practice. Ie #21s and #10s The basics / foundations were covered in an appropriate manner so that the text will not become out of date very quickly. Webopening section of a scientific paper that summarizes the research and conclusions. Also, there is no discussion of applications of next-generation sequencing (e,g, RNA-seq, ChIP-seq) that are commonly used today. This is not an enlightened book, but I have not found it to lack images and examples from across the spectrum of humanity. This statement on page 488 is not necessarily true: A geographically continuous population has a gene pool that is relatively homogeneous. Furthermore, for students who will only be taking one year of biology, I am confident that using this textbook will give them a broad overview of the field and introduce them to more specific topics that could help them in any major or career. Some of the links would not open, such as a video link illustrating the fluidity of membranes. Content seemed very up-to-date. I realize that it is impossible to provide this quality of artwork in an open source textbook, but I think it is also important to recognize how important such features are for students attempting to visualize complex structures and to master difficult concepts. In Figure 4.6: Relatives sizes on a log scale Where this text could be improved is in providing more practice questions and tutorials for students to check their understanding. Diagrams and written content both appeared to be accurate. Use of simpler language and less jargon would make the text more accessible to students from different backgrounds. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. While the textbook appears to be clear to me (someone with a PhD in biology), I wonder if it would be clear to my students? My main concern is that in some areas the book is already out of date and unless there are provisions for regular revision and updating it will soon become significantly out of date. From this perspective, I would have actually preferred if the text was less modular. The font in the online text is easier to read than the font in the pdf. Smith, Michael Abbott. As stated in the previous sections, book is well laid out to fit the needs of any entrance level biology course. Some of the charts and photos were a bit pixelated, but it didn't detract too much to the meaning of these photos/charts. I think students would also like this option.
