Unformatted text preview: Biodiversity practice questions for Exam 1 HI Folks, As I hope you gathered from what Irby said explicitly in class on Friday and what has already been posted on the web, there will only be about 12 multiple choice questions on Monday’s test. Given that we have only had about that many lectures, there will probably not be too many questions from each lecture. Thus, they will need to cover big topics and not picky small details. Irby said as much on Friday. Thus, you should look for major themes in the biodiversity lectures. Review the “Where we’re going slide” and make sure you understand the main point of each topic. Review the clicker questions, as I try to make those relatively general. There will NOT be questions of the sort, “How many flagella do stramenopiles have” or “name 4 taxa that we have covered that are capable of photosynthesis”. Also, don’t forget the activities you did in section and remember to bring your Lucky Pencil to class on Monday. Cheers, Cole Gilbert Here are some questions of the type that you might see on Monday. 1. Which of the following is NOT an example of the unity of Life? a. All organisms use nucleic acids as their hereditary material. b. All organisms use a triplet code of nucleotides to specify their amino acids. c. All organisms use proteins or riboproteins as enzymes. d. All organisms use mitochondria to generate ATP for energy. e. All organisms are composed of cells. 2. Linneas and Darwin would have organized the living organisms into a roughly similar arrangement. Which of the following concepts would have DIFFERED in each of their thinking ? a. More similar organisms cluster together b. Similarity is judged by morphological characteristics c. The arrangement is hierarchical d. The mechanism that produced the order e. The arrangement is composed of nested sets of similarity 1 3. Which of the following is NOT an example of the diversity of prokaryotic metabolic pathways? a. Some prokaryotes are chemolithotrophs. b. Some live in highly acidic aquatic environments. c. Some are able to use purple membranes to make ATP. d. Some are able to use carbon from small organic compounds. e. Some live in highly saline environments. 4. Which of the following does NOT provide evidence for a group (Archaea + Bacteria) ? a. Peptidoglycan in the cell wall. b. Single circular chromosome. c. The presence of plasmids. d. They both have a 70S ribosome. e. Lack of membrane ­bound organelles. 5. Which of the following is NOT a reason why phylogenetic relationships among prokaryotic organisms are somewhat difficult to discern? a. Their limited morphological diversity provides few characters. b. Horizontal transfer of genes confounds molecular methods. c. The 70S ribosomes of bacteria are more difficult to sequence. d. Difficulty of obtaining pure cultures makes it difficult to know which species you are working with. e. Phage transduction induces homoplasy. 6. Which of the following is an INCORRECT pairing of a taxon with a synapomorphy ? a. Cyanobacteria  ­ photosynthesis b. Excavates  ­ modified mitochondria c. Rhizaria  ­filamentous pseudopods 4. Plants  ­ primary plastid endosymbiosis 5. Archaea  ­ “shells” made of silica or calcium carbonate 7. Which of the following is NOT true of the basal eukaryotic groups? a. With a few exceptions, most of them a single ­celled organisms. b. Most of them are aquatic, or live as symbionts in aqueous tissues. c. The relationships are well worked out through DNA sequence analysis. d. Some are photosynthetic by 1o endosymbiosis, but others are 2o or 3o photosynthetic. e. The presence of mitochondria is a symplesiomorphy 2 ...
