Answer:
Since the origin of humans on this planet, they have been trying their best to make their lives easier on this planet. In doing so, human activities have some how heavily damaged the Earth. Many day to day activities of humans are dangerous for the Earth.
Some of the consequences of human activities on the Earth's fresh water are :
Extinction of many aquatic species:
The water consumed by humans comes from the fresh water oceans. As the population of humans is increasing enormously, the water from the oceans is being consumed at dangerous levels. This has caused many species of aquatic animals to become extinct or to be at a verge of extinction as they do not have a habitat to survive or reproduce.
Pollution:
Many heavy industries, house sewage, farmers dispose waste into the fresh water. Hence, killing aquatic animals and polluting the fresh water ecosystems.
Question is incomplete i have added complete question in ask for detail section and at the end of this question.
Answer:
b. using negative feedback to decrease blood glucose levels
Explanation:
When the level of glucose increases in the blood and become higher than the normal level a negative feedback mechanism is initiated under the control of hypothalamus. which increase the metabolism of excessive glucose level present in blood and hence results in decrease or normalization of glucose level in blood.

b. using negative feedback to decrease blood glucose levels
c. using positive feedback to increase blood glucose levels
d. using positive feedback to decrease blood glucose levels
Additional component that you may use to attach yourself to the tree include:
1. Climbing belt which you will attach round the tree when climb up and when getting down.
2. Tree strap which you will use to strap yourself to the tree when you are on the tree stand.

I believe D because non of the answers above are reality, humans are great at living in different types of environments and even tend to change there environment.
