Which is the main reason cells are replaced in the body? . the cells are too large.. the cells are inactive.. the cells are damaged.. the cells are cancerous.

The right answer is The cells are damaged.

Take the example of skin cells.  

The skin consists of two tissues:

* the outermost, the epidermis, resting on a vascularized connective tissue,

* the dermis.

In the epidermis, which includes several layers of cells, the outer layer is formed of dead cells that are desquamating and are constantly being replaced from proliferating basal cell cells. So, in normal conditions, the epidermis is in constant renewal.

On the other hand, when accidentally, the upper parts of the epidermis are damaged, for example, a slight abrasion or of a burn, the destroyed portion is regenerated (replaced) thanks to an accelerated proliferation of basal epidermal cells .

The correct option is the cells are damaged .

Explanation:

Cells are replaced by new cell because every cell have some life span after this they become older and damage, so cells divide to replace old and damage cells. Cells are further divided so that , living things can grow. For example, A organism grows, due to the regular division of cells not because of cell become larger therfore , organism  grows.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
