Which of the following is the function of adult stem cells?
a) provide a safeguard in case a limb transplant is needed.
b) provide a reservoir of cells for making gametes.
c) provide a source of cells for the body to replace certain types of cells that die.
d) provide a backup set of cells that can be used to grow replacement cells in the culture.

The correct answer will be option-C.

Explanation:

The stem cells are the unspecialized cells which can form any specialized organs of the body as they are the pluripotent cells.

The stem cells in the embryos have the ability to form all the organs of the body but their function gets changed in adults. In human adults, the stem cells are mostly present in the bone marrow which form new cell only for the replacement of few cells but not for the formation of new organs.

Thus, Option-C is the correct answer.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
