hours after eating. It would be most reasonable to suspect that this person is suffering from:
A. inflammation of the appendix B. pancreatic malfunction C. peptic ulcers D. gallstones
8. Photosynthesis and cellular respiration recycle oxygen in ecosystems.
a) Explain how the metabolic processes of cellular respiration and photosynthesis recycle oxygen.
b) Discuss the structural and physiological adaptations that function in oxygen exchange between
a human and its environment.
9. Compared with the other terrestrial biomes, the artic has an extremely low level of diversity and
stored energy.
a) List 3 adaptations of artic organisms that allow them to survive in low temperature, poor soil
composition, and low yearly precipitation. Include an explanation of how those adaptations help
increase survival.
b) Describe a four-organism food chain that might characterize an artic community, and identify a
trophic level of each organism.
c)
The problems of survival of animals on land are very different from survival of animals in an
aquatic environment.
i.
ii.
Describe 2 problems associated with animal survival in terrestrial environments but not
in aquatic environments.
For each problem, explain an evolutionary solution (adaptation).
10. Interactions among populations may have an effect on the densities of the species that interact.
Predation represents an important interaction among populations. The curves below illustrates the
population densities of three species: a small herbivore, a larger herbivore, and a carnivore.
Identify which curve represents which of the species listed and then justify why by describing the
changes in the population densities of these three species over time.
11. Organisms differ from one another and yet share common characteristics.
a) Select two out of the six kingdoms and briefly describe 3 characteristics used to distinguish
between members of one kingdom and members of the other.
b) Describe 3 characteristics (at least one cellular and one molecular) that members of these two
kingdoms share.
c) Propose an evolutionary explanation for the existence of similarities and differences between
the two kingdoms.
