In order for a cell to divide successfully, the cell must first...duplicate its genetic information (DNA).
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Strands of hair originate in an epidermal penetration of the dermis called the hair follicle. The hair shaft is the part of the hair not anchored to the follicle, and much of this is exposed at the skin’s surface. The rest of the hair, which is anchored in the follicle, lies below the surface of the skin and is referred to as the hair root. The hair root ends deep in the dermis at the hair bulb, and includes a layer of mitotically active basal cells called the hair matrix. The hair bulb surrounds the hair papilla, which is made of connective tissue and contains blood capillaries and nerve endings from the dermis.
Positive feedback cycles always increase the response. Negative feedback cycles always decrease the response.
Positive and negative feedback mechanisms always work in antagonistic fashion to maintain a homeostatic balance of a parameter such as temperatures or pH in the body. Positive feedback is akin to a gas pedal while negative feedback is akin to a brake and reverse pedal.
Explanation:
An example of a parameter is blood sugar levels. Glucagon is a hormone responsible for positive feedback since it increases blood sugars when levels are low. Insulin, however, is a negative feedback hormone that reduces blood sugars levels when they are elevated. These two work antagonistically to maintain the right sugar levels in the blood.

The things that happened to the movement of molecules at the equilibrium is : the movement of molecules continues.
But during this time, it got no concentration gradient so there will be no net movement in any particular reason
hope this helps
