When human skin suffers a cut, the process of healing rapidly begins allowing for wound closure and healing within a few days. Keloids occur when skin around wounds continues to grow after the skin has healed. A disruption in the regulation of which cellular process is probably responsible for this condition

Options

A. Mitosis

B. Meiosis

C. Apoptosis

D. Phagocytosis

A

Explanation:

Mitosis is a type of cell division which takes place in living  organism during growth and development.Therefore it is ensures  the regenerations of cells and tissues during healing.

Therefore the restoration of new cells to the skin following injuries is due to mitosis.Since this is a multiplication division(2n) in which the daughter cells are exactly like the parents' cells the new tissues of the skin by mitosis, look exactly like the previous one that was injured.

In cases where the mitotic growth control is lost, the scare tissues of the injured part overgrows with granulation tissues and this leads to Kaloids.

      Its is a mass of Collagen Type 1.(Collagen is an  fibrous proteins  which has largest proportion in mammals).

Keloids  is characterized with pink or red coloration and elevation of the area,excessive growth of the area, with irritating  patch skin

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

the correct answer is anaphylaxis.

anaphylaxis is a condition caused by insect bites, foods, medications, manifested by tongue swelling, shortness of breath, vomiting, low blood pressure. it sometimes may occur without an obvious reason. it is treated with epinephrine injection.other tretments include antihistamines and steroids,
