Answer:
human activity
Explanation:
The wetlands and the coral reefs have gradually been destroyed by the humans and their activity. The wetlands were the first to be under the human influence and getting destroyed, while the coral reefs have come to have similar destiny in the last century. The reasons for the destruction are different. The wetlands have in general been destroyed on purpose, be it because they were epicenter of diseases, for making more land for agriculture, or making more land for settlements. The coral reefs have not been destroyed on purpose, but the human activity has resulted in lot of pollution of the ocean waters, as well as changes in the climate, and the fragile corals can not adapt quickly enough to these changes, so they die out quickly.
stopwatches, and computers. Describe how you might
use that technology to analyze this following problem:
How is a runner's speed affected by wind?
A tailwind will boost up the speed of the runner while a headwind will slow the runner down.
A tailwind is a wind that is blowing along the direction of the runner approaching. Whereas a headwind is the wind that blows opposite to the runners approach.
This happens because the body is actually running flat to the wind which gives a resistance to the wind flow. So the wind actually pushes the body forward or backward. If the wind is coming from back, the wind pushes the athlete towards front, increasing his speed by a few miles per hour. When the wind is coming from front, the wind is actually pushing the athlete backwards, which decreases the speed.
The wind also makes it difficult for the athlete to breathe, thereby decreasing the speed to a certain extent in general.
Answer:
I would set up the wind machine so it was blowing against people running. I would have it blow at different speeds in different trials. I would use a stopwatch to record the time of each trial for the runners. I would use the computer to help analyze the data from the trials.

It was the answer provided.
Answer:
Understanding how genes and the environment come together to shape animal behavior is also an important underpinning of the field. Genes capture the evolutionary responses of prior populations to selection on behavior. ... Many scientists study animal behavior because it sheds light on human beings.
