GENERAL HISTOLOGY

Detailed explanation-1: -Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Detailed explanation-2: -A negative feedback loop occurs in biology when the product of a reaction leads to a decrease in that reaction. In this way, a negative feedback loop brings a system closer to a target of stability or homeostasis.

Detailed explanation-3: -Examples of processes that utilise negative feedback loops include homeostatic systems, such as: Thermoregulation (if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high; glucagon raises blood glucose when levels are low)

Detailed explanation-4: -Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals.

Detailed explanation-5: -The answer is C. Negative feedback because it helps keep a system near a desired set point. Negative feedback is more common than positive feedback in maintaining homeostasis. A negative feedback system reverses a change in a controlled condition.
