In function in the;cell?;5) Identify 4 human;diseases that are viral in origin and the specific virus that causes them.;6) List 3 key;differences between prokaryotic and eukaryotic cells.;7) Provide examples of cells in the human body;that employ cilia and flagella.;8);What would be the most appropriate microscopy tool for visualizing the 3D;surface of a damaged bone? For viewing a thin slice of tissue stained with;hemotoxylin and eosin?;Module;2 Case;1);Why are enzymes critical to the function of cells? That is, why not simply let;chemical reaction occur without interference?;2);What type of molecules are enzymes (i.e., lipids, nucleic acids, etc)?;3);What wavelengths of light are best suited for use in photosynthesis?;4);Why is photosynthesis critical to nearly every life form, not just plants and;algae?;5);If animals exercise anaerobically (without sufficient oxygen) for an extended;period of time, lactic acid accumulates in their muscles and causes cramping.;In the context of cellular respiration, explain why this phenomenon occurs.;6);Briefly explain the function of ATP synthase and the importance of ATP to all;cells.;7);Why would a typical animal cell lyses (explode) if placed into a container of;plain water?;8);What is the difference between passive and active transport through a cell;membrane? Which method allows a cell to concentrate a substance inside itself?;Module;3 Case;1) To what kingdom would a;single-celled, nucleated, photosynthetic organism belong?;2) What clues indicate;that dogs are more closely related to cats than to lizards?;3) What features are;common and distinct between plants and fungi?;4) What was the important;scientific contribution of Carl Linnaeus?;5) What are Byrophytes?;6) Briefly explain the;function of xylem and phloem.;7) What are the unique;characteristics of Aves species?;8) In higher animals, what;systems are responsible for homeostasis?;Module;4 Case;1) Assume the;gene for dimples, d, is recessive. Then assume that two individuals with the;genotypes Dd and dd mate. Create a Punnett square for this mating and state the;probability that their offspring will have dimples.;2) Briefly;explain epitasis.;3) List the;steps of mitosis and briefly describe what happens in each;4) What is;the role of mRNA in the synthesis of proteins?;5) What is an;intron?;6) In the;process of protein synthesis, what is the difference between transcription and;translation?;7) For;animals, what is the advantage of internal fertilization and what type of;species utilize it?;8) What is;the reproductive purpose of fruits?;9) What is;the genetic advantage of sexual reproduction?;Module;5 Case;1) Why is the;Hardy-Weinberg law useful?;2) Define genetic drift.;3) What factors influence the mutation rate of a population?;4) Briefly explain the difference between stabilizing selection, directional;selection, and disruptive selection.;5) Why are layers of sedimentary rocks particularly useful for geochronology?;6) Choose three biomes and briefly describe their characteristics (including;climate, common organisms, etc).;7) What is the difference between an ecosystem and a biome?;8) What is the role of primary consumers in a food chain? Give an example of a;primary consumer in a terrestrial and an aquatic ecosystem.;9) What are niches and competitive exclusion?
