d)

Hollow bones give birds a tube-like shape.

5.

Male grasshopper use sounds to attract female grasshoppers for mating. According to what we learned about Natural Selection, if their sounds are overpowered by urban noise pollution, select the things that could happen to their population:

The population will fail to reproduce and die off.

b)

The males with sounds of a different frequency will be heard. Only they will be able to reproduce with the females.

c)

Grasshoppers will decide to reproduce asexually so that their species do not become extinct.

6.

In the medical field, which of the following is related to Natural Selection and is a great concern for human health?

a)

Certain animals such as dogs and cats are becoming more domesticated, living side-by-side with humans.

b)

Certain bacteria are developing resistance from antibiotics.

c)

d)

The wild mustard plant is dangerous and is developing into different types of vegetables we commonly see in grocery stores.

7.

Natural Selection

b)

Artificial Selection

10.

a)

Someday, bacteria might replace humans as the dominant species in the planet.

b)

Someday, we might be able to do artificial selection on bacteria.

c)

Someday, the good kinds of bacteria (e.g. lactobacilli) will be outlived by the bad kinds due to natural selection.

d)
