EXAM REVIEW 2024 SBI 3U1 DIVERSITY 1. Correctly list the 8 classification levels in order from least alike to most alike. 2. Define taxonomy, binomial nomenclature, and species. 3. List the 6 kingdoms and major defining characteristics of each. 4. In detail, describe the difference between the lytic and lysogenic cycle of viral replication. 5. Bacteria can be classified according to their shape and oxygen requirements. Explain. 6. How does a vaccine protect you against a virus? 7. How does an antibiotic help with a bacterial infection? 8. What is the theory of endosymbiosis? 9. What is a dichotomous key and how is one created? 10. What is a phylogenetic tree? How do you interpret one? PHYSIOLOGY 1. Describe the complete digestion of carbohydrates, proteins and fats (triglycerides). In your answer include enzyme names, what they do, where digestion occurs, and how the nutrients are absorbed. 2. Name and describe the function of one digestive hormone. 3. Explain each term and its relation to the digestive system: peristalsis, saliva, bile, villi, pancreatic enzymes. 4. Define ingestion, digestion, absorption, egestion. 5. What substances are secreted by the stomach lining into the stomach? 6. Why do the enzymes released in the stomach (e.g. pepsin) not work in the small intestine? 7. What is the function of the large intestine? 8. State the functions of the circulatory system and blood. 9. What are blood antigens and antibodies? 10. Review the different blood types (universal donor and recipient). 11. What are the differences between arteries, veins and capillaries? 12. Trace the path of a red blood cell from the inferior vena cava to the aorta. 13. Differentiate between internal, external, and cellular respiration. 14. List the structures passed by an oxygen molecule as it moves from the nostril to an alveolus. 15. Briefly describe the mechanics of breathing: inspiration and expiration. 16. Define/explain the importance of each of the following: blood pressure, pulse, heartbeat (LUBB- DUBB), systolic pressure, diastolic pressure GENETICS 1. Review your genetics problems sheets and test. Don’t just read the questions. Practice them! 2. Differentiate between mitosis and meiosis with regards to: (a) the type of cells where it occurs, (b) chromosome # after division (haploid or diploid), (c) number of resulting cells, (d) functions 3. Describe the 2 ways in which genetic variation is created in gametes. Why is genetic variation important? 4. Describe the main stages of mitosis. 5. Explain the process of meiosis. Explain synapsis, crossing over and independent assortment. 6. Define: dominant trait, recessive trait, gene, allele, incomplete dominance, co- dominance, sex-linked traits, homozygous, heterozygous 7. Show the possible blood types of the children of a homozygous type A person and a heterozygous type B. 8. What are the possible phenotypes of a heterozygous normal visioned female and a male who is colour blind. Both are heterozygous brown eyed. EVOLUTION 1. What is evolution? 2. What type of evidence support his theory? 3. Differentiate between the different types of natural selection (directional, disruptive, stabilizing and sexual). 4. Define the term genetic drift and genetic bottleneck. 5. Define divergent evolution, convergent evolution, and coevolution. 6. Describe the 3 types of mutations in the context of the environment. 7. What is a vestigial structure? How do they support the theory of evolution? 8. Compare the theories of evolution as described by Lamarck and Darwin. 9. Use an example to support how artificial selection supports Darwin’s theory. 10. Describe the 2 main types of reproductive speciation mechanisms and give examples of each. 11. Differentiate between allopatric and sympatric speciation mechanism.
