Question

The surface of the villi in the small intestine is covered by a single layer of epithelial cells called enterocytes. Enterocytes absorb nutrients from the intestinal lumen as they move up the side of the villus. The enterocytes are shed from the end of the villus through apoptosis after 3 to 4 days. Consequently, new cells must be continuously supplied from the crypt and move up the villus. When a stem cell in the crypt divides, what are its immediate daughter cells?

A. a transit amplifying cell and a goblet cellB. another stem cell and a transit amplifying cellC. another stem cell and a goblet cellD. a transit amplifying cell and an enterocyteE. another stem cell and an enterocyte

Answer 1

B. another stem cell and a transit amplifying cell

Step-by-step explanation:

Stem cell is a special cell that has always known to exist in the body tissue right from the Embryo development in the carrier till the death of body. Stem cell are cell that renew and regenerate new cells from within and that makes it different from other type of cell in the body.

Once a stem cell begins to divide, it will produce daughter cells which are name as progenitor cells, transit amplifying cells, early differentiated cells, and fully differentiated cells. Note that, the development of the cell at each stage give birth to the 4 different names of Stem cell.

I hope this is helpful

Answer 2

B.

Step-by-step explanation:

basically when the stem cell in the crypts divides they formed daughter cells. One of the daughters from each of the original divided stem cells usually divides to form another stem cell, while the rest forms transit amplifying cell.These amplifying cells are capable of dividing multiple times until they are evenly differentiated(designated to specific function) e.g top globlet cells, enterocytes, tuft cells etc.
