Which of the following describes a negative feedback loop? a)when the heart rate is too high, the body sends hormones that continually increase the heart rate higher. b)when a pregnant woman is in labor, the body sends 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 sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows. d)when a person is jogging, the body sends hormones that continually decrease the rate of oxygen supply to the legs.

The negative feedback loop is a cyclic process or dynamics where the increase in activity or secretion of one substance causes a reduction in the activity or secretion of another dependent substance, and vice-versa. The image shows an example of a negative feedback loop where the cloud cover stops the process of evaporation.

The answer 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.
