Question 2

When Charles Darwin visited the Galapagos Island in the 1800s, he observed many types of organisms that were similar but lived on different islands. The four species of mockingbirds found on the Gapapagos Island are shown below. Each species lives on a different island. These species are very similar, but the Hood mockingbird has a longer beak than the other three species. Which of the following best explains this difference?

Accepted Answer

The Hood mockingbird's longer beak is an adaptation to the food available in the bird's habitat.

Answer

The hood mockingbird needs a longer beak for defense against predators.

Answer

The Hood mockingbird originated from a different type of bird than the other species.

Answer

The Hood mockingbird's beak stretched to reach its food, and the longer beak was passed down to its offspring.

Question 3

Giant salvinia is an aquatic plant that floats on water and reproduces rapidly. When these plants die, decomposition by bacteria affects oxygen levels in the water. As more plants die, less oxygen is available in the water. Students observe a pond covered by giant salvinia.

Accepted Answer

Fish populations in the pond will begin to decrease.

Answer

The depth of the water in the pond will increase.

Answer

The amount of bacteria in the pond will suddenly decrease.

Answer

The number of different types of plants around the pond will increase.

Question 13

If global climate change leads to the elimination of snow in the habitat of white-tailed ptarmigans, which adaptation is most likely to occur over many generations?

Accepted Answer

Birds with white feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year.

Answer

Birds with brown feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have white feathers throughout the year.

Birds with brown feathers will be easier to see on the ground in the winter. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year.

Question 14

Scientists are studying the effects of climate change on the Baltic Sea. Some scientists predict that if current trends continue, the Baltic Sea will become less salty, and it will contain less dissolved oxygen. As a result of these changes, the Baltic Sea will have less biodiversity.
