Amarine biologist is examining the effects of oil pollution on a population of birds known as seagulls (larus canus). she is particularly concerned that oil pollution may reduce the number of eggs raised in a seagull nest. during one breeding season, she counted the number of eggs present in a sampling of six seagull nests near each of the 14 refineries throughout the state. she discovered that seagulls laid and raised an average of four eggs per season. to confirm her hypothesis, the researcher must now examine seagull nests that have not been exposed to oil pollution. the researcher believes she is correct, and so expects to find a) 0-2 eggs per nest. b) 2-4 eggs per nest. c) 1 egg per nest. d) 4-6 eggs per nest.

4.06 hc)a five-year review of threats to the southern resident orca population of the united states concluded that the top threats were prey availability, contaminants, and effects from recreational and whale watching vessels. further down the list are oil spills, disease, and effects from commercial vessels not targeting whales. how might this list be different if it were for transient whale populations, which have a larger average population size and live farther offshore in open waters? a)the transient population is more likely to be affected by contaminants. b)the transient population is less likely to be affected by whale watching vessels. c)the transient population is more likely to be affected by disease. d)the transient population is less likely to be affected by prey availability.
