Answer: Option B

Explanation:

The upper forelimbs of human beings and bats have similar skeletal structures but the same structure has resulted differently in whales.

This is because the natural selection in whales has resulted in change in anatomy and this change in whales has changed their anatomy.

The forelimbs of whales has changed into flippers and it helps whales in swimming.

The forelimbs of human beings, whales and bats have the common ancestors but because of different environment they evolved differently.

State one of the goals of environmental science and why it is important.
telo118 [61]

Answer:

One of the major goals of environmental science is to understand and to solve environmental problems. In order to accomplish this goal, scientists study two main types of interactions between humans and their environment. One area of focus is on how we use natural resources, such as water and plants.

Explanation:

Environmental science is important because it enables you to understand how these relationships work. For example, humans breathe out carbon dioxide, which plants need for photosynthesis. Plants, on the other hand, produce and release oxygen to the atmosphere, which humans need for respiration.

vampirchik [111]
