However, as with any subject, certain topics in generally biology (e.g. In Figure 20.7: For example, the bones in the wings of bats and birds have homologous structures. This is a poor example, since these wings are both homologous as vertebrate forelimbs and analogous as wings. Textbook content produced by OpenStax is licensed under a Creative Commons Attribution License . Although alternative splicing is mentioned in Chapter 16, it should be described in Section 15.4. This book follow the traditional, and most widely used, manner of organization for the sequence of chapters and topics, which allows for a logical flow of content. Some chapters have abstracts and other chapter dont. However, it still seems slightly dated even with this consideration. However, they are inconsistent in the quality of the website links. The rest of the content is current and relevant. The variation of individuals within a species is due to genetic factors, environmental factors, and their interactions. This is a guaranteed trouble-spot because the field is experiencing so much revision. I would like to see greater use made of graphical phylogenetic hypotheses ("phylogenetic trees") in the diversity overview sections, and in other areas where the evolution of key characteristics is discussed. The art is well done and has clear images that are well labeled. Overall, the organization is much like the intro textbooks from major publishers that Ive used in the past, and it would be easy to assign specific sections rather than whole chapters. I found this text responded well to being reordered as each section sat on its own. 2 Review Questions - Biology 2e | OpenStax Review Questions Review Questions Highlights 4. The topics that travel into an introductory biology text are topics that are rarely controversial or inadequately supported by scientific vetting. glycogen. I use Openstax Biology 2e as a textbook for my AP Bio and dual credit class. The bar codes associated with each Link to Learning were fantastic and an excellent addition to the textbook to add additional information. Reviewed by Robert Sorensen, Professor, Minnesota State University Mankato on 6/10/15, The 8 units this textbook, chemistry through ecology, sufficiently cover the range of topics that would be covered in an Introductory Biology series of courses.The order in which topics are addressed follows the common approach of building from At the level of details, I found a few places in the text in which terms were used before they were defined, though in such cases they were usually defined in the following paragraph/page. Systematics could be another trouble spot, but the authors do OK presenting an up-to-date, albeit conservative phylogeny. ATP. As an Amazon Associate we earn from qualifying purchases. In filtration, material moves according to its concentration gradient through a membrane. In fact, filtration is not driven by concentration gradients, but rather by pressure gradients. It includes video embedded that will be updated as needed. These are some tough topics for students that could be explained more clearly with more examples. Some of the figures did not match well with the text. Reviewed by Conner Sandefur, Assistant Professor, University of North Carolina Pembroke on 6/19/18, This text covers all subject matter used in a one semester introductory biology course. This structure is also attractive to instructors as it allows us the freedom to pick and choose textbook content to assign. One critique is that the learning outcomes at 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. Good to have a glossary at the end of each chapter but the definitions could have more depth and research.

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. I have not noticed any grammatical issues but did find some of the sentences to be too long or awkwardly constructed. This evidence suggests that the cephalochordates diverged from Urochordata and the vertebrates subsequently diverged from the cephalochordates. Nope, thats out of date. There is coverage of all levels of organization and no bias is evident in coverage of molecular versus ecological topics. I did not find any issues with the interface, and especially liked the option of reading it online. I only felt that the jargon got to be a little technical in some of the genetics unit, especially within Genes and Proteins and Gene Expression. WebTotal Pages Answer Key N/A. Since first looking at this text a year ago, I have been very impressed with the quality and comprehensiveness. For instance "anabolic pathways require an input of energy to synthesize complex.. is accurate. 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. Figures should be introduced after text throughout each section. Sections will need to be fully revised to provide updates of text and figures. The chapters are divided into topical sections, making it easy to assign or not assign specific topics. Creative Commons Attribution License The text is easily readable and helps make complex topics easier to navigate. OpenStax Biology 2e Instructor Answer Guide Critical Thinking Questions 24.Describe the different cell types and their functions in sponges. I did not read these in any depth because I write my own problems for students. I learned quite a bit myself from reading it, and I look forward to teaching courses where I can use this book's material to help explain concepts in biology. The presence of a membrane-enclosed nucleus is a characteristic of ________. I felt like there was too much detail on some processes, and too little detail on other topics. Why are two base pairs (T-A and incorrectly labeled C-G) shown? Every summer, a new PDF of Biology is released and print stock is updated for the following Fall. then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, There are many genes on our autosomes that affect primary and secondary sexual characteristics (including the potential to affect some aspects of gender expression). Creative Commons Attribution License Biology 2e works through cellular respiration diligently and thoroughly, making it very useful as a reference text. The contents on the left side of the page make navigation very easy and you can easily switch to different sections to find the information that you need. Poor use of page space / too much white space also makes this text a poor fit for reading online, particularly on devices such as iPad, tablet, eReaders where screen size is smaller and the text /content is intended to fill the entire screen space. For example, there is a box in the plant section discussing whether green algae are considered as plants. The contents list expands readily, and the names of the chapters mirrors those in the competitor texts. Some other errors included some minor semantics issues within a few of the chapters, including the genetics and immune system chapters. Some of the figures in the PDF have very small components that cant be magnified (they just become pixelated if one tries). The figures have an overall similar look and parts of them are colored the same way for consistency for example the homologous chromosomes (blue and red). During my review, I noticed some things i would correct. In general, the terminology and nomenclature is consistent throughout the book. I used the PDF version to read/review this text and that avoided many of the problems with the online version, and highlighting and notes are available on many free PDF readers. Reviewed by Laurie Lawson, Associate Professor, Tidewater Community College on 1/30/23, This online textbook covers most chapters for the biology 101 and 102 courses taught at TCC. 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. Should a student wish to purchase a physical copy, they can do so at a very reasonable rate. I did find a couple of minor errors that are not related to conceptual issues. I really like the model of open and free materials and admire the work, but the quality is really low. In fact, recent genomic evidence shows that hagfishes and lampreys form a clade, the cyclostomes: Hagfishes and lampreys share four unique miDNA families. The text reads well and has no grammatical errors. The online interface is clear, easy to use, and free of problems. The text includes information on various jobs in biology, as well as information on many human health conditions. The line width of text on the pdf download was a little wide for easy scanning, I would prefer a two column per page format, but that may simply be personal preference. The integration of career connections are an added bonus. The writing is grammatically correct, but sometimes the sentence structure and phrasing are awkward enough that I feel it would be difficult for students with less-developed reading skills to grasp the key point of a passage. The problems I read through struck me as sensible and mostly straightforward. read more. A weak spot was that bold-face words were not always defined in the text. The text is available in multiple formats: online, pdf, app, print, and iBook. Instead, climate change is dealt with separately. I did not examine all of the review questions in the 26 chapters I engaged, but I came across one that to my mind rises to the level of error (Section 19.1 Population Evolution. It includes both the cell biology and organismal biology required of a 2-semester biology post-secondary sequence. The text book used various external resources with both female and male voices. Text is well-written and does not seem to be overly technical. Reviewed by Mark Wagner, Instructor/Life Sciences, Portland Community College on 6/14/21, I found the book to cover the topics in good depth, definitely a lower division, major-level text A very general discussion of linkage analysis of two genes is included in chapter 13, but very little information or opportunity for practice is provided, and no information on how gene order can be inferred from linkage distances. This book uses the The correct answer was identified as A. While that answer is obviously more correct than the others, it is certainly incomplete and misleading. Images in the text also do not make a very good use of space. I found few errors. It is comparable to most conventionally printed textbooks in being fair, but not great. It would be useful for a variety of styles of classes. The text is easily searchable by key words (Ctrl F). The depth of content is largely appropriate for a 200-level Biology class. I think all these factors can enhance the learning experience and increase students' subject-matter comprehension. Cell biology gets more cursory coverage and evolution is surprisingly There are numerous areas that could be improved, but none that I have seen that stand out as warranting complaint. However, any such statements could easily be clarified or amended, so I think this book will have good longevity. 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. x][su~8\rh dG7oWQB?mvTzw}f6Utgf^P|KY_>J77e[M]e[>}h~>VP|~.)Rg<4~w}W]wKYy\WG_H6C5Ow-?C=@g'ZfS+ATW;>D8{Hx-A\94d#mBghN7q We biologists know that chromosomes do not entirely "determine" a person's sex. ISBN. However, some have low resolution, which makes their interpretation difficult. For example, Cell Communication, Cell reproduction, Mendelian genetics and non-mendelian traits, DNA replication and repair and mitosis and meiosis I believe are covered adequately. Each chapter is arranged in smaller, manageable subdivisions. Sections are numbered within chapters, which makes it easier to assign parts of chapters. Females possess two X chromosomes while males possess one X and one Y chromosome." The concepts are covered fully and are presented in a way that information can easily be scaffolded for a particular learner/course. This is a laudable grade for the first iteration of an enormous community project. I would definitely consider adopting this textbook for a non-majors introductory class at the freshman level. I prefer a different order that introduces DNA before Mendelian genetics, for example ( as in Brooker Biology). This books covers the minimal basics, but not in great detail and isn't comprehensive by any means. The table of contents is not available on each page, so navigation other than directly forward or backward is difficult. Thanks for all you have done !! I found the illustrations to be very instructive and easy to interpret. Any ethical issues (for example, reproductive technologies) were handled carefully but with technical accuracy. I felt like there was too much detail on some processes, and too little detail on other topics. 19. Frequently, however, the flow seems stilted and information presented out of context or out of order. This text avoids the use of ethnocentric names and concepts as far as I can see. In the sections I plan to use, there is consistency. The authors' voices are clear and the text is easy to follow and understand. The clarity of the text is very well done. I currently teach 9th grade Biology. 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. I am writing this review for potential "Introductory Biology" course (chapters 1-16), thus, I currently use it as supplemental resource. The book followed a typical format of introducing biological concepts starting with cell and ending with community biology. One of the great benefits of this textbook is its ability to be updated without the need for students to purchase a new edition. I feel the text is mostly accurate, but as in any large text, the occasional error slips by editors now and then. This is often a matter of opinion across Biology professors, so that is not surprising. Any possible problems can be easily fixed or updated. It covers the main topics such as genetics, evolution, and cell biology in sufficient detail. It would be helpful for my objectives to have a stronger treatment of invertebrates. 1171-2 are covered with weakly explained equations and values in mm Hg. While not in detail, most of the material covered gives the reader a basic understanding of various biological processes. From Plant Sensory: Pathogen defense, Herbivory defense, Electrical signalling, Auxin transport, Acid growth hypothesis, Auxin regulated gene expression End-of-chapter questions are included for students to check their understanding. The references to recent research areas is an asset. As noted above, the chapters can be covered in any order as instructors prefer, but the overall outline of the units and chapters fits perfectly with any standard biology course taught over one or two terms. 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. Content is very up-to-date, and I did check out how frequently the content was altered (it mentions this at the bottom of the online version). There could be more cultural references in the examples of careers sections. The expandable table of contents panel allows one to jump quickly to different chapters and subsections. From Flowering: Circadian rhythm biology, Photoperiod detection, ABC model. Indexes and glossaries are good, which is important because definitions are often not given in the text. Each chapter subsection starts with 3-5 clear and concise learning outcomes. The book included biological themes beginning at the cellular level and progressing all the way up to the community level in accordance with a conventional structure. This is especially important at my institution where our introductory sequence for life science majors consists of two free-standing semester-long courses: Organismal and Ecological Biology; and Cellular and Molecular Biology. This is a strength of the text, considerably easier to use in that way that most texts I have examined. Do you have a earthscience corner? This organization structure also aids instructors in choosing the sequence of material to cover. The textbook has taken good advantage of the use of figures in describing concepts and structures. Easy to read. However, in order to sustain student interest, it maybe useful to add a few more examples where biological concepts are applied to daily living making this subject more interesting to the reader. read more. Images and figures need revision as many are displaying with poor resolution in the pdf version. Putting these pieces together would help students gain a more unified understanding of cellular respiration as one component of larger biological processes. The chapter sections are well defined and accurately titled. storage carbohydrate in animals. There is one image of a white woman scientist and there are two dark-complexioned individuals with skin conditions. Several features are included to help the learner and educator alike. (ID: 349a8a47e1d944c18f9bdae4af018fe7) electrophoresis technique used to separate DNA fragments according to size helicase Should our understanding of cellular respiration or fermentation change, the chapter should be easy to update. This is consistent across the textbook, with the chapters following what I would consider to be a logical flow. Where in a phylogenetic tree would you expect to find the organism that had evolved most recently? The addition of vocabulary terms and definitions at the end of each chapter aid in clarifying any concerns with terminology. Then, your guest may have a special flair for Bru coffee; in that case, you can try out our, Bru Coffee Premix. No internal links were dead or misdirected, and figures were clear. My concerns over the writing are more about clarity and consistency (as described in those sections of the review) than technical usage. I taught an earth science class last year for the first time and was thinking about compiling those resources. Additional content should be added regarding topics such as pseudoscience and the influence of social media and politics on science. Hello!
