Wildfires are frequent in the great basin shrub steppe. every time there is a fire outbreak, much of the natural vegetation is destroyed. what is the most likely impact of fire on this ecosystem? a) a drastic reduction in the animal population due to migration or death by starvation. b) no impact, because the plants have only been temporarily removed from the ecosystem. c) there would be no rainfall because there are no trees or shrubs in the region. d) non-native plants and animals would migrate into the region.

Suppose that on a small island off the coast of scotland, 32 percent of the population has blue eyes, which means that these individuals must be homozygous for the blue eye color gene (bb). the only other eye color found on the island is brown, and individuals that are homozygous for the brown eye color gene (bb) or heterozygous (bb) will have brown eyes because brown is the dominant gene. assume this population is in hardy-weinberg equilibrium. if 100 babies are born next year, how many of these would you expect to have brown eyes and be heterozygous? a. 58 b. 49 c. 29 d. 43
