Question

Which of the following best describes negative feedback?

It causes an effector to signal the control center, which creates the stimulus to make a response.
It counteracts a change in a condition by causing the change to stop or to be minimized.
It produces a response by lowering a set point in the organism’s metabolism.
It promotes decreases, rather than increases, in an organism’s metabolism.

Answer 1

I think it is C but correct me if i am wrong hope this helps.

Answer 2

It counteracts a change in a condition by causing the change to stop or to be minimized.

Step-by-step explanation:

Negative feedback is one that is characterized by reducing a certain stimulus and reversing the direction of change that was taking place. It is responsible for the secretion of most hormones and is directly related to the maintenance of homeostasis, that is, internal balance.

We can cite as an example one of the most classic cases: the regulation of the amount of sugar in the body. When there is an increase in blood glucose, right after eating, for example, there is an increase in insulin rates. This hormone ensures the absorption of glucose by cells and the synthesis and storage of glycogen in the liver, thus decreasing blood glucose levels. Note that in this case, the increase in glucose triggered actions that lowered its level, showing that negative feedback tries to maintain the body's internal balance.

In summary, we can say that negative feedback neutralizes a change in a condition, causing the change to be stopped or minimized.
