openstax biology 2e answer key

Biologists refer to this fit as adaptation, and it is a consequence of evolution by One critique is that the learning outcomes at General coverage is good the text covers all of the areas Id expect to see in an introductory biology textbook, including behavior, which I find is sometimes overlooked. The abstracts are a good concise summary of what the chapter intends. Creative Commons Attribution License On page 52, the text states, Like hydrogen bonds, van der Waals interactions are weak attractions or interactions between molecules. Reviewed by Sarah Foltz, Assistant Professor, Radford University on 1/14/20, General coverage is good the text covers all of the areas Id expect to see in an introductory biology textbook, including behavior, which I find is sometimes overlooked. One of the great benefits of this textbook is its ability to be updated without the need for students to purchase a new edition. These provide real world examples as to why they are learning these topics and how they can be applied to a career or are being used by other scientists and professionals. The process of ________ helps to ensure that a scientists research is original, significant, logical, and thorough. read more. This text was written in a more straight-forward manner than my current text that I am using. The genetics section of this book appears to be consistent. There is unevenness in accessibility across chapters. The coloration of these figures should also be improved for contrast. Therefore in order to reach this audience effectively (to help them retain material), it is better to have a few more images. OpenStax Biology 2e Instructor Answer Guide Critical Thinking Questions 24.Describe the different cell types and their functions in sponges. It would be nice to have links to the full-sized image. I have the .pdf file from Openstax broken down into chapters, which I share with my class over google classroom. I was going to also review it for "Animal Form and Function" but the quality was so poor I decided not to spend my time. But, in the case of mitosis, the lack of a good figure of the mitotic spindle is notable. The information provided is up to date and comparable to similar texts. I understand. I did not find anything culturally insensitive. The first forms of life on Earth were ________. There is no reason to dwell on this metric, as the grammar and English were fine in all the chapters I read. Getting students to read textbooks is always a struggle and so I do think that making the layout appear less daunting would be an improvement. The textbook is comparable to a general biology textbook for majors from any of the major publishers. In another case, for videos on enzyme function, the web page opened, but the enzyme videos were not visible on my old MacBook Pro running Safari 9.0.3. Alternate ISBN (s) 9781506699851. This textbook has some such examples which is commendable. The text is easy to read with consistent flow and rationale. Many terms are used before they are defined. In fact, throughout the textbook, bacteria are mentioned in contexts where bacteria and archaea should both be included. 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. That said, it isn't particularly cutting edge, either in terms of content, or in its approach to teaching. The book is consistent every chapter is clearly laid out in a good order and would make a great book for freshman biology majors. They followed the format of most other textbooks making a transition to OpenStax from Cambell or Biology in Focus simple. Some are terrific, and worth a student spending time there to better understand the material. The unit and chapter organization are logical, and comparable to other texts. Each chapter and subsections within each chapter are set up similarly with chapter glossaries, summaries, and questions occurring at the end of each chapter. Biology was very comprehensive in its covering of general biology topics and the "Link to Learning" feature allows the learner to expand the concept. Its generally well-written. Key terms are defined at the end of each chapter. While it puts major discoveries into some historical context (Mendel is discussed at length) it forgoes that context in more recent discoveries (epigenetic and its historical context). Nowhere does the text point out that attaching a phosphate with its -2 charge will necessarily cause a change in the conformation of the protein, and taking that phosphate back off will cause a change back to the original conformation: that cycle causes the protein to do physiologically useful activity, from powering the movement of sodium and potassium across membranes to the movement of a myosin head. Weballosteric inhibition. This text book is as comprehensive as the McGraw Hill and Pearson texts that we have been using. I dont see any glaring errors in terms of subjects that are missing from the text. I think visibility might be even more of an issue on a cell phone, which I know many students use to view their digital texts. Ie #21s and #10s Within chapters some of the graphics are labeled art connection, evolution connection, etc. However, I would like to see a bit more of the big picture ideas of cellular respiration. Where this text could be improved is in providing more practice questions and tutorials for students to check their understanding. In Chapter 3, the Evolution Connection on cytochrome C is not well explained: When human and rhesus monkey sequences were compared, the single difference found was in one amino acid. Majority of the figures and charts in the "Art Connection Figures" are very difficult to read. Figures rendered well. Modularity is consistent and adequately divided throughout. The flow of the text as it begins at lower levels of biological organization and moves up to the highest levels follows a typical format of many introductory texts. This review was collaboratively written by Dr. Heidi Sleister and Dr. Debora Christensen. The overall organization of the course material is consistent with how it is taught at many institutions. Intermittently, the text refers to itself, which could be an issue if one has not read the previous information, but this is not frequent. Chapters are broken down into easy-to-assign modules. Each chapter has a number of small photographs, After each section, you can click the link and it brings you to a relevant video, activity, etc. Therefore, I conclude that the text is neither culturally relevant, nor culturally insensitive. 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. Depending on your choice, you can also buy our Tata Tea Bags. The interface is straightforward and gets the job done. The topics are presented and arranged in a traditional manner as most biology textbooks and as taught in many colleges. read more. I did not notice cultural insensitive in this book; it includes mention of women scientists (Figure 14.16 Elizabeth Blackburn, telomerase) and discussion some genetic disease that occur more frequently in particular populations. Chapter 23 provides a foundation. It was easy to download and view. I found it had enough depth for a majors course while being accessible for non-majors. It has a good online index that is searchable. This is often a matter of opinion across Biology professors, so that is not surprising. On page 96, the text states, The structural difference between a normal hemoglobin molecule and a sickle cell moleculewhich dramatically decreases life expectancyis a single amino acid of the 600. No, the sickle cell hemoglobin only decreases life expectancy in homozygous individuals. The organization makes sense and flows well. Nitrogen fixation and plant defenses are not well explained, and deamination and cation exchange dont come up in a search. Atoms that vary in the number of neutrons found in their nuclei are called ________. Biology 2e seems to go into slightly more detail in some places, especially in regard to molecular biology. Hopefully this is not an issue when the pdf is accessed from a desktopI'd have preferred to have all animations open in a new window. My students do a lot of Google image searching to supplement graphics. I like that the chapters are fairly short. I taught an earth science class last year for the first time and was thinking about compiling those resources. My students have always struggled with the ever-higher page count zoology or integrative biology textbooks. I have found the content for this purpose mostly comprehensive, with some need to supplement. I would agree that the relevance is one of the strengths of the textbook. Overall, This OER textbook is a well-designed biology textbook that gives a clear, consistent, and thorough presentation of the subject matter, so assisting students in developing a solid grasp of the concepts and principles of biology. Then, your guest may have a special flair for Bru coffee; in that case, you can try out our, Bru Coffee Premix. The book is easily adaptable. The web based interface is simple and clean, and not overly complicated. Many figures are not readable until viewing at 200% or even 300%. As no comprehensive textbook like this is ever completely error-free despite the best of intentions, I am sure there are some inadvertent mistakes. And in the discussion of hypothesis testing only controlled experiments are addressed. and you must attribute OpenStax. Finally, each chapter has review questions, both multiple choice and short answer (critical thinking). The format od each section should be consistent across reading platforms. 4. 18.1 too dark. Lots of options are provided for accessibility. Population genetics is the study of: I selected Cellular Respiration because this is a complex, multi-step concept which is challenging for many students. Do you have a earthscience corner? In truth, both fields are equally rigorous and important, they just study different parts of our world. Nursing students, business majors and arts students would like the easy to read and brief descriptions in this book. The presence of a membrane-enclosed nucleus is a characteristic of ________. The text describes the reactions in steps, but they are not accompanied by labels on the figure, which I think is a shame. It is good to be able to search the documents easily because they are online. The basic content doesn't seem to be at any more risk of becoming dated that a traditional text. Specifically stating which pages the specific answers could be found would be even better. read more. The text book is easy to navigate with essential and well chosen figures and links to outside resources, some very good and simple animations. (b) What volume would this air occupy at room temperature and 1atm1 \mathrm{~atm}1atm pressure? Graphics The textbook explains very complex topics in a comprehensive manner and appears to be designed for early term biology and 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. Of course, different professors will emphasize/ignore different details, but I would imagine that any professor would have to skip over a lot of the jargon in some places. Diffusion plays a key role in the movement of molecules across plasma membranes, which are only 8 nm thick. This example most closely resembles which type of reasoning? The bar codes associated with each Link to Learning were fantastic and an excellent addition to the textbook to add additional information. I did not notice grammatical errors in the text or figures. Unless I missed it, the R in Figure 2.27 is undefined. Navigate to openstax.org/subjects, 2. Except where otherwise noted, textbooks on this site The book followed a typical format of introducing biological concepts starting with cell and ending with community biology. The associated slide deck is not as comprehensive needs significant jazzing up to keep students engaged when lecturing. It would make more sense to discuss the topics as they arise than to briefly mention and revisit later. Of course this applies to any textbook. One surprisingly omission in this section is the lack of total ATP yield from oxidative phosphorylation. Some of the links on the textbook take you to trusted sources such as Khan Academy and TED talks, but others dont look very reliable to me. 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. When more depth is required, other web sites and tutorials can be added to the students' reading materials. I found no problems with the links within in the text and I was surprised by this since I myself often have issues year to year with broken links. All of the websites mentioned in the text do make me a little nervous. The text in that section was correct, but an incorrect figure can easily confuse students who are not familiar with the topic. They are very helpful. In some cases, it appears that the authors do not fully understand them. I feel the text is quite readable, concepts do not require much interpretation, and students do not appear to get lost in a concept, In no case did I find a chapter that appeared inconsistent with the overall quality of the text., nor clarity of concept, It does fit well into the organization of our curriculum, though I would prefer that the discussions of Evolution be moved to the beginning of the text, and more emphasis put on the role of Evolution in life, As above, I'd prefer that evolution be discussed in the first section, The book is very easy to read, concepts are well presented, and illustrations support the writing very effectively. Could these figures, tables, and text link to online databases (e.g., https://www.gbif.org/species/search) that are retrieving species data on a more regular basis? You already know how simple it is to make coffee or tea from these premixes. The material is presented in an engaging manner and should hold the students attention. (ID: 349a8a47e1d944c18f9bdae4af018fe7) electrophoresis technique used to separate DNA fragments according to size helicase Atoms that vary in the number of neutrons found in their nuclei are called ________. The biologically accurate terms are ectothermic and endothermic. With the downloaded pdf or (I am assuming) the printed text version, the glossary comes at the end of the chapter. read more. The text is clear but perhaps a little dry and sparse. Reviewed by Dan Atwater, Assistant Professor, Earlham College on 6/23/19, The comprehensiveness varies but is overall mostly appropriate. Overall, it a text that is a good value for students to learn basics of biology. For me, a text book is a resource of basic information that allows the students to learn a bit on their own (the critical basics) before applying their knowledge to in class activities. The prose is consistent and accessible to students. In any case it is an instructors responsibility to supplement with the latest understanding and findings as they may pertain to a course. Thank you! In fact, not only are there no such problems, but many of the examples used demonstrate a clear commitment to human (and other biological) diversity. Reviewed by Pat Boleyn, Adjunct Faculty, Lane Community College on 8/21/16, The text is comprehensive in its coverage of the typical materials for a non-majors introductory biology course at the 100 level. With a few exceptions, the textbook addresses relevant issues in biology while also presenting historical findings. It provides a path to cut student cost while still maintaining rigor. My attempt to use a QR code scanner app of a mobile phone on the PDF of the textbook on a laptop screen didnt work and clicking the URL indicated the link was no longer current. Typo in bicarbonate image in Ch.2 Also within chapters are QR codes and URLs that take the reader to animations and movies on the OpenStax website. The topics are presented in a logical, clear fashion, with minimal searching for an area of interest. I I have been teaching general biology for 25 years, during which time I have used traditionally published texts. On page 159, crenation does not mean shrinkage but refers to the effect of shrinkage on the cell membrane. P.459 I think linkage maps belong elsewhere. 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. Acids and bases will neutralize each other. It also seems easy enough to omit or shift order to fit one's preferred teaching plan given the clearly titled subdivisions in each chapter. It presents the same problems if one wishes to teach topics out of order, which is that the student will have to pay attention to the section they are currently teaching on as not all professors go in chapter order. It is as culturally relevant as would be expected for an introductory biology textbook. I do think that the book misses several opportunities to have a more critical look at the use of science, but it thankfully does so in a side bar on eugenics. The book is comprehensive and suitable for use in a 2-semester (year long) college-level biology/science majors general biology sequence. 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. I did not find any grammatical errors when using this book. The unit and chapter breakdown was very well done and organized appropriately. Overall, the organization is good, probably because it follows longstanding conventions. I found the index and glossary complete; it was easy to find topics of interest and the completeness of the topics matched my expectations from the index. The small text-box presentations of examples of the scientific method throughout the book were well executed. One example will suffice: there is no mention of the CRISPR-cas9 gene editing method which even the general public is aware of now because of extensive media coverage of the work of Dr. Jennifer Doudna and others. Using the terms soft and hard to differentiate between biological and social sciences simply furthers the divide between the two and also imparts a value judgment where "soft" sciences are not viewed as rigorous or quantitative as biological sciences. Mostly, the internal text seems consistent. The book followed a typical format of introducing biological concepts starting with cell and ending with community biology. I think it is a great alternative to using a for pay text, and with the multitude of formats (browser, pdf, app, print) it can be accessed in the format that is best for a particular student. The text provides students with current, relevant information in a progression of topics and concepts based on empirical data and basic science. From my perspective this is the weakest part of the text, and unfortunately early on, one that I must rectify in my teaching. The topics speak to contemporary relevance. As with any textbook, minor errors have made their way into the book. Chapters 28 and 29 on invertebrates and vertebrates, respectively, provide an overview of the major phyla. I did not find any culturally insensitive material. The writing style is easy to read and is well written for the freshman/sophomore level. I did also have trouble opening one barcode. The textbook also has an assortment of web links that will need to be maintained. Organization is appropriate and is adaptable for the specifics of individual course requirements. My suggestion would be not to completely overhaul the text exactly but maybe update the ancillary materials in a way that teachers and students are introduced to new discoveries and new techniques on regular basis. read more. Sometimes (as in other textbooks) the historical chronology of discovery appears to supersede the relevance as we understand it today. This explanation on page 58 is overly simplified: So how do the cells of the stomach survive in such an acidic environment? Which of the following sequences represents the hierarchy of biological organization from the most inclusive to the least complex level? Frequently, however, the flow seems stilted and information presented out of context or out of order. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Therefore, the physiology section could be edited to recognize that sex steroids are not the domain of one sex specifically, as both estrogens and androgens play important roles in all humans and animals, regardless of sex or gender. Reviewed by Melissa Kilgore, Biology Instructor, Lane Community College on 6/20/17, The textbook covers all of the major topics that I address in a year of non-majors biology. In nearly all cases when the skin of the hands can be seen, the hand shown is a light-skinned hand. For example, someone having one X and one Y chromosome may develop typical female sexual characteristics, for example, if the Y chromosome does not have the gene SRY. The section on the terrestrial biomes discusses only the temperate forests of the eastern part of the U.S. I don't find it to be any more modular than a rather textbook, however. 12. The topics follow the fairly standard structure of a inclusive general biology text. There are no grammatical errors, and the language is not overly complicated in terms of sentence structure and organization. If you are throwing a tea party, at home, then, you need not bother about keeping your housemaid engaged for preparing several cups of tea or coffee. 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.
