Which statement does the article support?

A. Exposure to low levels of sunlight causes the genetic mutation for lighter eye pigmentation.
B. Exposure to too much sunlight causes the genetic mutation for lighter eye pigmentation.
C. Genetic mutations do not occur in populations unless they create a survival advantage.
D. Genetic mutations can have positive consequences instead of negative consequences.

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.
