openstax biology 2e answer key

I have only used the online interface, which had no issues. The information in each unit is well organized and follows the levels of biological organization well. The graphics were small and not at all rich. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Overall, this book provides a mostly adequate resource for teachers who are trying to save on textbook costs. For each section there are 2-4 objectives for the students to focus on. The text covers the appropriate breadth of material in appropriate depth for an introductory biology class. The text is easy to read with consistent flow and rationale. Figure legends were descriptive. In general, chapters are arranged in a logical order, and topics flow seamlessly within chapters. Nothing caught my attention regarding Canadian content. Many topics are covered at a moderate level of depth with additional links provided to content from other sections of the text We are proud to offer the biggest range of coffee machines from all the leading brands of this industry. They aren't just in the book, they are incorporated into the discussion. In future versions of this book, could the learning outcomes of each chapter be aligned with V&C? Otherwise I had no interface issues. For these reasons, I think this would be a very difficult text for a new instructor to teach from. Overall, I found this to be an exceptional textbook option for the cost. Click on the cover of the book for which you would like to submit a correction., 3. Again, this seems to reflect a lack of understanding on the part of the authors, as the inaccurate terms are used consistently. I have not encountered grammatical errors in the text. I noted several examples in which material is explained clearly in one part of the text, with inaccurate or inconsistent information in other places. ATP. There is no list of references at the end of each chapter to the literature. For instance, serendipity is defined right away on page 22, which I thought was odd to define that in a Biology text. Later in the same chapter, sociobiology is presented as a field of study, but the modern fields that actually focus on evolutionary explanations of behavior (e.g., Neuroethology; Behavioral Ecology) are not. We focus on clientele satisfaction. It provides a path to cut student cost while still maintaining rigor. Most of the "skin tones" colorized in these diagrams where light beige to pinkish tan, but it would be easy to resort to a pale olive tone or even a neutral light grey if a darker brown tone would make it difficult to visualize the line drawing of the system portrayed in the image. Which of the following sequences represents the hierarchy of biological organization from the most inclusive to the least complex level? The short video is correctly labeled as dispersion in Wikipedia rather than as diffusion. The text covers essential content in sufficient detail for an introductory and/or non-majors biology survey type course. The answer guide available to verified instructors (verification is simple and takes about a day or two) is useful. read more. Text does not seem to be written in a way that will make it obsolete any more quickly than any other textbook. While some topics and visuals are redundant across chapters, this also helps with modularity of the text. The book is similar in scope to the textbooks mentioned above and follows a conventional topic and chapter sequence, with molecular and cellular topics (plus genetics and evolution) in the first part of the book and the more organismic topics and ecology occupying the rest of the book. I would agree that the relevance is one of the strengths of the textbook. Even less accurate, the text goes on (p. 386) to say that Sangers genome sequencing has led to a race to sequence human genomes at rapid speed and low cost, often referred to as the $1000-in-one-day sequence. This explanation on page 58 is overly simplified: So how do the cells of the stomach survive in such an acidic environment? The text does not dive into the controversy, merely puts forward the biological information as it should. It covered all of the subject areas that my current General Biology textbook covers. For example, there is a box in the plant section discussing whether green algae are considered as plants. Our mission is to improve educational access and learning for everyone. Im sure there are many more. It was easy to navigate the contents list, and very easy to switch from one section to another. Everything is formatted correctly and links and images are accessible on both devices. There were also some chapters that were sparse of images, including the genetics unit - in particular the information about cancer. Any student who can download Acrobat can search for vocabulary terms I assign. read more. One of the best features is the Everyday Connection sections, which are imaginative and will be interesting to students. When the authors have constructed their own images, they are rather basic by modern standards, but that is not a bad thing in my view. read more, I found the book to cover the topics in good depth, definitely a lower division, major-level text, While I found a few instances where I disagree with the text, but they are minor. Use of bolded key words helps readers pick out important terms. The references to recent research areas is an asset. It would be nice to have links to the full-sized image. 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. The interface is simple. read more. I havent gotten that far ahead, though Ill probably be skipping that one for now since I dont plan to cover it until next semester. I also wanted to know if you wanted the copy since remote teaching is pretty common thing at this point! In my review, I focused mainly on Units 1 3 (Chemistry, The Cell, and Genetics) as those encompass the topics that I typically address in the first semester of General Bio. There are some nuances of classification and speaking in generalities that could lead the learner to think in terms of absolutes where that may not be the case (ie. The text appears to be very comprehensive. That said, more and more scientific discoveries require extensive team work, making the worship of individual scientists -always questionable- impossible. d. the degree of inbreeding in a population 11. As an Amazon Associate we earn from qualifying purchases. The overall framework makes it easy for students to find what they are looking for and they are not constantly adapting to a changing layout. This review will focuses specifically on a representative chapterin this case, Chapter 7: Cellular Respiration. Complete the following page as thoroughly as possible. 5. Urochordate and vertebrate embryos share a novel embryonic tissue layer: migratory neural crest cells. There was also links to videos and tutorials which more fully explained some of the more difficult topics in a visual and/or audio dimension. It's a solid traditional biology text. While this may be of concern in an upper level text, I think that is still acceptable here. In general, the content to me felt like a classic introductory biology set of material. 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. Vending Services (Noida)Shop 8, Hans Plaza (Bhaktwar Mkt. Formatting issues are numerous throughout and a uniform layout would be a welcomed addition to each section and should include a link to current events in biology. However, the textbook is set up to explain the subject of biology starting from broad (chemistry/building blocks of life) to specific (organ systems) and going from simple (cells) to complex (ecology) and therefore could easily be assigned sequentially as well. More vocabulary is presented which is a good thing to expose the students to. Reviewed by Aruna Kilaru, Associate Professor, East Tennessee State University on 4/13/20, This book will serve the purpose of introductory biology and could very well be used in place of the expensive textbooks. One exception: it appears that there is an error on page 150 in the image labeling frontal and transverse planes in the goat (at least the image doesnt seem to match the description in the text). (other than the colour/color thing) There are no issues with the download at any time and website does reminder the reader to use the chrome or any other web browser than IE. Reviewed by Christopher Sorenson, Instructor, St. Many more instructor resources are offered with just about any text on the market. One thing that was kind of annoying is that you encounter hyperlinks for figure and you click it and it really doesnt do much. The body of this chapter is readily understandable, with a level of clarity similar to other texts. However, I can't say for sure that one order is better than the other for student learning. However, unlike most textbooks, it is simple for anyone to submit a correction, so these errors are corrected more efficiently than can be done for most textbooks. This book teaches them the basics every biology major should become It covers the main topics such as genetics, evolution, and cell biology in sufficient detail. Alternate ISBN (s) 9781506699851. In some cases, the text over-focuses on certain topics while omitting others. Its the lignified schlerenchyma cells. These are concise and provide a better big-picture summary than the text I currently use, where students often become overwhelmed and lost in the details. Generally, having so many possible ways to access the material makes the interface exceptionally positive for students. GitHub openstax / cnx-recipes Public Notifications Fork 14 Star 5 Code Issues 81 Pull requests Actions Projects Security Insights New issue While, in general, the amount of detail and depth is also appropriate, the balance of coverage could be improved. Terms and concepts are used consistently throughout the book; there are no problems in that regard, even if this book was written by a big team of authors. Concepts All areas of introductory biology were covered. WebCh. I do have one other caveat: I had difficulty finding and accessing instructor resources. If this statement were true, the energy of ATP could not be used to supply energy to reactions within cells. The text wast not culturally insensitive of offensive and when used examples where cultural diverse throughout the text. 2nd Edition. Good, but a bit variable in quality. From photosynthesis: cyclic reaction in photosynthesis, CAM and C4 photosynthetic adaptations, Fate of triose-P after Calvin Cycle, Any regulation of photosynthesis These images are similar or complimentary to others displayed in the main text, and labeling them as Art seems strange. The Figures in the textbook are also generally accurate. Reviewed by Joan Sharp, Senior Lecturer, Simon Fraser University on 10/9/13, The text covers most necessary areas, but not always with clarity or accuracy. The Career Connections are a nice feature. Graphics You have saved me many hours of work. The information and real life examples provided in the text are both up-to-date and relevant. 4. Difficult concepts can be presented in image form as supplemental material. and you must attribute OpenStax. One, the figures are sometimes bare-bones. In Section 10.1 (p. 280) on genomic DNA, the text makes a distinction between character and trait (a tricky concept for many students) but then conflates the two on the following page (referring to hair color as a trait instead of a character). This text is very comprehensive, covering all topics that should be included in a two semester undergraduate introductory biology course for Biology majors/premedical students. I didn't notice any major errors, but there were some omissions, especially in the evolution section, which is a disaster. Reviewed by Lily Arias, Lecturer, University of Illinois at Urbana-Champaign on 1/1/20, The textbook is comprehensive; the extent and depth of the topics and concepts covered are at the level required in an introductory course for biology majors. The organismal themes are oriented toward animal function and structure (which can be found in the majority of the book), with only a cursory coverage of plant structure and function (similar to what is found in the majority of biology textbooks). This book does do a good job of being modular. I advise reviewing and using review questions with caution so that students are not conceptually mislead, or think the questions are isomorphic with your own assessment questions. ions neutrons neutral atoms isotopes 6. I also think that the consistent lumping of Archaea and Bacteria together as prokaryotes is out-of-date (see my comments on this above). The chemistry of life and macromolecules in biology have to be discussed before gene regulation which itself has to precede the various organ systems. There really is nothing this book doesnt provide that I would absolutely need as an instructor to teach my course. I do not understand why it is not more widely adopted. On page 313, the explanation of The Red Queen Hypothesis in the Evolution Connection is very weak and unclear. However, I now realize that instructors are encouraged to cut irrelevant material and use relevant material to their coursework. It is mostly a long long list of descriptive paragraphs. If you are redistributing all or part of this book in a print format, Smith, Michael Abbott. 7. My concerns over the writing are more about clarity and consistency (as described in those sections of the review) than technical usage. WebAnswers will vary. Students would benefit from learning about totipotency and tissue culture, development and growth, phytohormones and associated signaling mechanisms etc., in plants, Each chapter is provided with much useful key terms and definitions, chapter summary and review questions. Systematics could be another trouble spot, but the authors do OK presenting an up-to-date, albeit conservative phylogeny. The online version has additional organizational features that connect glossary terms with each subsection, rather than an entire chapter or even at the end of the book. But overall regardless of the depth of information in the figures; they appear accurate. The integration of career connections are an added bonus. This is well done and contributes to student learning as concepts will build upon one another as higher levels of organization are discussed. On page 479, the text states that Natural selection [is] also known as survival of the fittest. This outdated phrase is not challenged or revised. Colored images work better for the students since I emphasize that is publisher is paying more for the color it must be important. Chapters 28 and 29 on invertebrates and vertebrates, respectively, provide an overview of the major phyla. This book focuses on proper concepts and details, not extraneous stuff. It was easy to download and view. This will make it quite easy to assign specific parts of a chapter. This is a great chance to show the accomplishments of a brilliant woman. The book included biological themes beginning at the cellular level and progressing all the read more. Granted that the texbook is "inaccurate" with respect to T cell subpopulations (at this detail level), but if one wants to know more about T-cells, then perhaps an Immunology textbook would be more appropriate! thank you so much! b. the genetic basis of population-wide traits As mentioned, there are not long blocks of text that most units and chapters are divided into short, directly linkable chunks. Another example occurs in the chapter on cells. This is outdated terminology that has no place in a general biology textbook. You can even purchase a bound copy from Amazon for around $60, which is very reasonable for a textbook. As is the case with most biology textbooks, the focus of the organismal topics are heavily biased towards animal structure and function (10 chapters), while plant structure and function (3 chapters) are poorly covered. I I have been teaching general biology for 25 years, during which time I have used traditionally published texts. The text describes the reactions in steps, but they are not accompanied by labels on the figure, which I think is a shame. To fix this, I would recommend that authors periodically check and change these links accordingly. Jan 9, 2023 OpenStax. The OpenStax name, OpenStax logo, OpenStax book covers, OpenStax CNX name, and OpenStax CNX logo It is acceptable for a general reading level. Most of the material taught in introductory biology courses has not changed in the last 15-20 years and this book is certainly up to date. 2nd Edition. Only issues I've found are in the accuracy of illustrations -- several are mis-labeled. Easier import power into different LMS platforms. I liked being able to click on a link in the index or table of contents, which takes the reader directly to a specific page within the book. 4.8, 5.4, 5.19, 33.21, 33.23, 34.19, 40.17, 38.38, 41.13, 41,13, 42.11, 43.15, 43.17, 46.6, 46.10; there are many more examples like these. The major textbooks in Biology offer numerous, diverse learning resources, including audience response programs, test banks, adaptive learning software, etc. For me this could not have come at a better time in my life. Images in the text included a variety of people from different races and backgrounds. 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. One very serious weakness of this text is the art: the figures, the animations, and the Art Connection features. While there were a few typos, I noted no grammatical errors in the text. Reviewed by Archana Lal, Associate Professor of Biology, Labette County Community College on 4/6/21, The book is quite comprehensive and covers all aspect of biology that one can choose from to cover in an introductory biology course. The information provided is up to date and comparable to similar texts. As I looked at the units, their order, and the titles, I found a very familiar feel, like I could have been looking at the table of contents of several well-known commercial textbooks. A weak spot was that bold-face words were not always defined in the text. Text is already in its second edition. 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. Both of these could almost be considered typos, except for that they risk confusing students. American spelling is used throughout, which is fine with me. The book is very consistent and the formatting is carried from one chapter to the next, making it easy to navigate. In Figure 45.10, there is no such thing as the carrying capacity of seals. This alone happens at a frequency of perhaps 1 in 20000, and there are a great number of additional ways in which a persons chromosomes might not follow the statistically most common pattern. There are many genes on our autosomes that affect primary and secondary sexual characteristics (including the potential to affect some aspects of gender expression). Topics such as biotechnology and conservation/ecology will, of course, have a quicker update cycle as new technology is developed and example animals are driven to extinction. I also found the external links to be extremely beneficial and well selected. It is mostly a long long list of descriptive paragraphs. As with any science textbook, periodic revisions will be necessary for many of the units. Biology was very comprehensive in its covering of general biology topics and the "Link to Learning" feature allows the learner to expand the concept. In Mendel's chapter, the text gives a brief, insufficient description of topics like linkage and independent assortment that would confuse a student and then only at the end of the chapter does the text cover these in depth. This textbook has some such examples which is commendable. While it is not as polished as a traditional text, I feel that the advantages it offers far outweigh the costs. Also helpful is the ability to highlight within the text, only requiring a simple log in. Among the three domains, the archaea are not given adequate treatment. While the authors have consistently kept descriptions to the minimum, it would be unfair to expect great explanations for the various topics in biology some of which we have entire courses designed for them. This makes it easy to expand on particular topics, replace a section with other reading, and tailor the text to the objectives of a course. I did not find any grammatical errors when using this book. There is a figure error in the description of prokaryotic transcription, but the text is correct. Atoms that vary in the number of neutrons found in their nuclei are called ________. Biology (OpenStax) is as comprehensive as, and follows the general topical format of a commercially available introductory biology textbook designed for life science majors. Presentation is straightforward, but I find that supplementing with additional web based teaching tutorials and videos, compliments this basic text. My current use of this textbook has only portions of the text assigned, and this does not seem to be an issue for students. Diagrams and written content both appeared to be accurate. The text is easily divisible into smaller reading sections just by including the link to the text in a syllabus and specifiying which sections need to be read. Thanks again for all of these!
