As part of maintaining homeostasis, why are hormones, secreted by endocrine cells, continuously inactivated?
IceJOKER [234]

Answer:

Homeostasis refer to as the maintainence of equillibrium within the body. Endocrine systems play a major role in maintainence of equillibrium. The hormones released are continuously inactivated by negative feeback system to maintain homeostsis.

Explanation:

Homeostasis in a body is refered as a dynamic equillibrium which constantly changes. Feedback regulation systems maintain homeosatsis.

The release of hormones into the blood is controlled by a stimulus. A stimulus can increase or decrease the release of hormones.The response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.

There are two types of feedback systems.

Negative feedback occurs when the response to a stimulus reduces the original stimulus. Positive feedback occurs when the response to a stimulus increases the original stimulus.

If the hormones released are not controlled by these feedback systems, enormous amount of hormones will change the whole internal enviornment of the body ,hence, equillibrium will be disturbed and result in death of cells and death of an indivisual.

Rufina [12.5K]

N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on

a. inheritance of natural variations

b. inheritance of acquired characteristics

c. natural selection

d. survival of the fittest

Inheritance of acquired characteristics. Thus, option "B" is correct.

<h3 /><h3>What is inheritance of acquired characteristics?</h3>

For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.

Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution
