5.
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

Brown beetles have a shorter life cycle than green beetles have
b)
Green beetles are more fit for their environment than brown beetles

brown beetles are undergo more unfavorable mutations than green beetles
7.
A graph regarding the effect of agricultural bioengineering on insect pests is shown below How has natural selection affected species of insect pests?

A. Natural selection has not affected the number of species that are resistant to pesticides
b)
A. Natural selection has rapidly increased the number of species that are resistant to pesticides

A. Natural selection has only affected the number of species that are resistant to pesticides
8.
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?
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.
9.
During a study session about evolution, one of your fellow students remarks, "The giraffe stretched its neck while reaching for higher leaves; its offspring inherited longer necks as a result." Which statement is most likely to be helpful in correcting this student's misconception?
a)
Disuse of an organ may lead to its eventual disappearance.
b)
Spontaneous mutations can result in the appearance of new traits.
c)
Only favorable adaptations have survival value.
d)
Characteristics acquired during an organism's life are generally not passed on through genes.

11.
If two modern organisms are distantly related in an evolutionary sense, then one should expect that
a)
