All the Review Questions for Final

Here they are folks, all the questions we discussed in class.

1. What are three strategies plants have developed to survive in the cold dry, and sometimes dark conditions of the Tundra?

2. In what biomes does fire play an important role, and what is this role?

3. How is a parasite different from a parasitoid?

4. How is a parasite different from a predator?

5. In pea plants purple flower color (P) is dominant to white (p). If a plant heterozygous for purple flowers is crossed with a plant with white flowers, what proportion of the offspring will have white flowers?

6. What are common strategies predators use to capture prey, and common defenses found in prey?

7. Colorblindness is an X linked recessive trait. Susan carries the gene for colorblindness, and her husband is not colorblind. What is the chance they will have a colorblind son? What is the chance they will have a daughter who is colorblind?

8. What are two important factors in determining what type of Biome one will find in a given area?

9. What causes the seasons here in North America?

10. What is a rain shadow, and how does it account for different plant communities occurring at the same latitude, but on opposites sides of a mountain range?

11. What word (or phrase) describes each of the following genotypes? TT Tt tt

12. What is the difference between genotype and phenotype?

13. Coevolution happens also between parasites and their hosts. Why is this not surprising?

14. Two normal parents have a child with a recessive disorder. What are the genotypes of each parent?

15. To what kind of environmental stresses are the plants and animals in the chaparral adapted?

16. How is a deciduous forest different from a coniferous forest, other than the types of trees found in each?

17. Why are there fewer members of the upper trophic levels as compared with primary consumers or the producers?

18. Why don't grasslands become forests?

19. What is the one thing all deserts have in common?

20. Dad has AB blood, and mom has O blood. What are the possible blood types of their children?
21. Define resource partitioning and give an example of it.

22. What kind of adaptations have animals developed to survive in:
A. The tundra
B. The deserts
C. Coniferous forests

23. Why is it that the evolution of a predator would affect the evolution of its prey?

24. In one species of flowering plants there is some diversity in flower color. Some plants have blue flowers, some have red, and others have purple flowers. What type of inheritance do you suspect controls this trait, and why?

25. Define and give examples of the following: Mutualism, Commensalism, social parasite.

26. Draw a food web that could occur in your backyard or here at Cerritos. Include all the trophic levels we discussed in class.

27. Which of Mendel's laws addresses homologous chromosomes separating from each other during meiosis?

28. In mice dark fur (D) is dominant to light fur (d) and short fur (S) is dominant to long fur (s). If two mice heterozygous for both traits are crossed, what proportion of the offspring would you expect to have dark short fur?
