Answer: The answer is C!!! :D maintaining homeostasis by regulating the body's temp!

Explanation:

Shivering as a natural, involuntary response to generate heat is an example of  maintaining homeostasis by regulating body temperature.

Homeostasis refers to the maintenance of a relatively constant body environment. The normal range of operation of the body system is known as the setpoint.

When the setpoint temperature for some animals is breached, a negative feedback mechanism is used to return it to the setpoint. Shivering to generate heat is a response to a cold environment when the body's temperature is about to drop below the setpoint.

The oppositeis sweating. Sweating causes cooling and comes in response to when the setpoint temperature is exceeded.

Hopes this helps happy early Christmas!!!! :D

Lubov Fominskaja [6]

Answer:

Gradually, as generations of elephants continued to selectively use and develop their trunks.

Explanation:

Jean-Baptiste Lamarck was  famous French Naturalist. He was a soldier, a biologist and an academic. He gave an early theory of evolution known as the theory of Lamarckism.

It was Lamarck who first believed that elephants earlier had small trunks. But eventual when there was scarcity of food and water, the elephants stretched out its trunk to reached out for food such as trees and also water. And as a result their offspring inherited long and powerful trunk.

In his theory of Lamarckism, he believed that the species passes on its traits to the offspring which they acquired through their use in their lifetime. In this case, the elephants might have used their trunks in such a way that they became long and strong over time and they passed tis trait to their babies.
