Which process is responsible for the growth and repair of human tissue ?
muminat

In general, the process responsible for the growth and repair of human tissue is the healing process, which takes place in three phases.

1. inflammatory response. Injured tissues release  chemicals that draw resources to the area, alert the body that damage has occurred and inhibit function to prevent further injury.

2. Repair phase. Once injured area is walled off and debris removed, construction to  replace or repair injured tissue begins. New blood vessels grow in the injured area maximizing transport within tissue.

3. Remodeling phase. Construction of permanent tissue , typically strong scar tissue made from dense network of collagen fibers. 

Looking at it from cell level, the process of mitosis is actually taking place during  healing. 

Mitosis is used for growth and repair and produces diploid cells identical to each other and to the parent cell. 

New cells are needed throughout life. These are for growth and replacement of damaged or worn out tissue. The body obtains such through the process of mitosis.

agasfer [191]

Answer:

Hawk

Explanation:

Dichlorodiphenyltrichloroethan which is also known as DDT is a colorless, tasteless and almost odorless crystalline chemical compound. It was originally developed as an insecticide and it causes harm to wildlife animals.

When the chemical are sprayed or gets in contact with the soil it is the terrestrial organisms such as plants and primary consumers who gets affected the most due to direct contact with the chemical.

Animals such as hawks who are arboreal and tertiary consumers from the list of options don’t get affected directly from the source of the DDT contamination which makes them least affected.
