Question

Which of the following describes a negative Feedback loop? A) When the heart rate is too high the body since hormones that continually increase the heart rate higher B)When a pregnant woman is a labor in the body since hormones that increase the intensity of contractions which then increases the secretion of the same hormones C)When blood sugar is too low the body since hormones that raise blood sugar until it reaches a typical level and hormone secretion slows D)When a person is jogging the body since four months to continually do you kris the rate of oxygen supply to the legs

Answer 1

The correct description of a negative feedback loop is when the body sends hormones to raise blood sugar until it reaches a normal level and then slows the hormone secretion, which can be seen in option C).

Step-by-step explanation:

A negative feedback loop is a homeostatic process that works to maintain stability in the body's internal environment. It functions by reversing the direction of a change, bringing levels back to an ideal state and thereby restoring balance. In response to a stimulus that moves conditions away from this state, a negative feedback mechanism will induce an action to counteract the change until a set point is reached, at which time the process ceases or is reduced.

An Example of Negative Feedback

The most accurate description of a negative feedback loop from the options provided is C) When blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows. This mechanism utilizes the hormone glucagon to increase blood glucose levels, a classic example of negative feedback in action.

In contrast, options A, B, and D describe processes more akin to positive feedback mechanisms, where the body's response is to amplify or continue the direction of the change, such as increasing heart rate or the intensity of contractions.
