Which of the following is not a negative feedback mechanism of homeostasis in controlling human body temperature (thermoregulation) ?

A. Shivering

B. Sweating

C. Insulin Secretion

D. Vasodilation

D - vasodilation

Vasodilation is the widening of the blood vessels, it results from relaxation of smooth muscle cell within the vessel walls. It's not an example of negative feedback mechanism

Explanation:

What is homeostasis

It's a tendency of an organism or a cell to regulate it's internal environment and also maintain equilibrium using a system of feedback controls.

There are two types of feedback mechanism

We have both positive and negative feedback mechanism

The negative feedback mechanisms in living things regulate critical body processes.

Examples are : body sweating, body shivering, regulstion in sugar level.
