• bats pollinating flowers at night

• birds and insects pollinating flowers during the day

• herbivores trying to eat spiny plants

Which of these scenarios describes an example of natural selection?

• Pugs are bred by humans to have flatter noses and smaller bodies.

• Brussels sprouts and cauliflower are gradually produced from wild cabbage when farmers select seeds from the plants with traits they want to see in the offspring.

• A moth population gradually changes the color of its wings in response to changes in its environment.

• Ranchers breed cows that produce milk with more cream to cows that produce a lot more milk, resulting in cows that produce a lot more milk with higher amounts of cream.

The fur of pocketmice in a desert biome are mostly tan in color. Then, after a volcanic eruption, lava covers much of the sand. When the lava cools, it turned black. Which mutation would be most beneficial for the pocketmice?

• A mutation that makes their tails much longer

• A mutation that makes their fur color darker

• A mutation that makes their eyes see more color in daylight

• A mutation that makes their ears much larger

Polar bears have very thick fur and a large amount of stored fat (blubber). Are these adaptations structural or behavioral and which climatic condition are they adapted for?

• Structural. Seasonal snows and freezing temperatures.

• Behavioral. Very cold nights, hot days, and strong winds.

• Structural. Year-round extremely cold ocean and air temperatures

• Behavioral. Hurricanes and tropical storms.

Florida panthers are nearing extinction because there are too few of them left and their litters are very weak and small. Scientists are trying to breed them with other species of panthers that have large healthy litters of offspring. Which answers explain how this would help the Florida panthers survive? Select two.

• The other breeds of panthers have harmful traits that would be passed down to the Florida panthers’ offspring.

• If Florida panthers breed with other species, their offspring will get weaker and their litters will get smaller.

• The Florida panther offspring would inherit some traits from the other panther species. This would make the offspring more genetically diverse.

• The new traits inherited from the other panther breeds may allow the Florida panther to survive changes in its environment and reproduce more successfully.

• The offspring will always inherit the stronger traits of the other panther breeds because they are dominant.
