selection
12.
Why did the population of peppered moths in England change from light to dark after the Industrial Revolution produced a lot of pollution?
a)
Light moths were easy to see against sooty trees and were eaten
b)
Light moths were killed by soot
c)
The birds that ate the dark moths were killed by soot
d)
Dark moths were produced by industrial processes
13.
Why is the mouse population changing over time?
a)
The light mice can reproduce more successfully than the dark mice
b)
The hawks eat more dark mice than light mice because the dark mice taste better

The hawks eat more light mice than dark mice because they can see the light mice more easily
d)
The hawks eat more dark mice than light mice because they can see the dark mice more easily

a)
death of the organism in which they develop
b)

17.
Which statement correctly explains how resistance to penicillin appeared after a few years of its widespread use to fight bacterial infection?
a)
in order to survive exposure to penicillin, bacteria developed a resistance to the drug
b)
a few bacteria became resistant to penicillin, and through sexual reproduction , most bacteria acquired the resistance
c)
penicillin never really successfully wiped out populations of bacteria, scientist did not use proper controls in their studies
d)
some bacteria were resistant to penicillin and their population spread rapidly, without competition from bacteria that were killed by penicillin
18.

The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table contains some information about this frog.
Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?

a)
A. It increases the probability that some offspring will survive long enough to reproduce.
b)
It increases the chance of the recombination of alleles, leading to genetic drift in the population.
c)
A. It increases opportunities for offspring to compete for limited resources.
