have terminally differentiated.

Answer 1

The correct response regarding skin cells is:

have terminally differentiated.

Skin cells, particularly keratinocytes, are terminally differentiated cells that form the outer layer of the skin. They do not have the ability to divide and renew themselves indefinitely like stem cells do.

Answer 2

Which cell type undergoes terminal differentiation?(1 point)
Responses

epithelial cells
epithelial cells

stem cells
stem cells

heart cells
heart cells

hair cells

Answer 3

The correct response is:

epithelial cells

Epithelial cells undergo terminal differentiation as they mature and become specialized for their functions, such as forming protective barriers, secreting substances, or facilitating absorption and sensation. While heart cells and hair cells can also undergo terminal differentiation, the most general answer among the options is epithelial cells.

to repair damaged tissue
to repair damaged tissue

to cause a cell to grow

Answer 7

The correct response is:

to repair damaged tissue.

Mitosis is the process of cell division that results in two identical daughter cells and is essential for growth, tissue repair, and asexual reproduction. While it can contribute to cell growth indirectly, its primary functions include repairing damaged tissues and replacing dead or dying cells.

Answer 8

Responses

cytoplasm

organelles

Answer 9

The correct response is:

cells.

During mitosis, a single cell divides to produce two identical daughter cells, effectively replicating the cell itself. While organelles and other cellular components are also distributed between the daughter cells, the primary focus of mitosis is the division of the entire cell.
