Question

Which of these is an example of negative feedback? which of these is an example of negative feedback? as a blood clot begins to form, the process of its formation gets faster and faster. after you eat, glucagon stimulates an increase in blood sugar levels. after you eat, insulin stimulates the lowering of blood sugar levels. the digestive enzyme pepsinogen is converted to pepsin by th?

Answer 1

Negative feedback in homeostasis is exemplified by the regulation of blood glucose levels. Insulin lowers high blood glucose levels, while glucagon raises low blood glucose levels, thereby maintaining balance.

Step-by-step explanation:

An example of negative feedback in homeostasis is the lowering of blood glucose after a meal. When blood glucose levels are high, the pancreas releases insulin, which helps to absorb the excess glucose, converting it to glycogen to be stored in the liver. This serves to lower blood glucose levels back to a normal range. Conversely, when blood glucose levels are low, the pancreas releases glucagon, promoting the conversion of glycogen back into glucose, thereby raising the blood glucose levels. Negative feedback mechanisms are essential for maintaining the stability of physiological systems.

The correct answer for which of these is an example of negative feedback is a. lowering of blood glucose after a meal. The processes of blood clotting and uterine contractions during labor are examples of positive feedback mechanisms, where the product of a process leads to an increased production.

Answer 2

A feedback is a statement or an opinion that is directed upon the input, so this is like an act of returning. In this case, a negative feedback is something which sounds bad or terrible about the input. The negative feedback from the choices is:

after you eat, glucagon stimulates an increase in blood sugar levels

No one wants to have high blood sugar levels, so this is negative.
