Which examples show repair or replacement of damaged cells? 1. A scrape being healed. 2. Scars forming where a cut once belonged. 3. Skin flaking off your arm in the winter.

Respuesta :

Cell damage or cell injury is defined as the suffering of the cell due to external and internal environmental stresses. The cell damage can be repaired by the scarring process.

The correct option is:

2. Scars forming were a cut once belonged.

Scars are the formation of a thick layer of the dermis where the cells are damaged. The process of formation of scars on the site of damage is known as the scarring process.

For instance, the cells when damaged or injured form the new tissue or group of cells referred to as scars. The scars are the sign of replacement or repair of the damaged cell.

The dermis repairs itself by growing the new cells at the site of the wound, in which scars are made. Scars are made up of collagen which seals the wound and is therefore known as the replacement of damaged cells.

Therefore, the scars are formed when the cells are damaged or injured as a replacement.
