Answer:
This question lacks options, the complete question is: What do you think would have the greatest effect on the body—a harmful mutation in a pluripotent embryonic stem cell, or a harmful mutation in an adult multipotent stem cell?The correct answer is a harmful mutation in a pluripotent embryonic stem cell.
Explanation:
Pluripotent Stem Cells can self-renew and differentiate into any of the three germ layers, which are: the ectoderm, the endoderm and the mesoderm. These three germ layers subsequently differentiate to form all the tissues and organs within a human being. If during embryonic development, genetic mutations - alterations in genes - occur in the embryonic stem cell, they pass to daughter cells as a consequence of cell division, and an individual is generated whose cells differ at the genetic level. Multipotent stem cells are organospecific cells, that is, they can give rise to any type of cells but from a specific organ (a lung, a kidney or the brain). Their differentiation ends the moment they specialize and become a cell with a specific function within a specific tissue or organ. If there were a mutation in these cells, it would damage a specific designed tissue or organ.

Answer:
Pancreas secrets two hormones called insulin and glucagon which helps in maintaining the glucose level in the blood.
Explanation:
Pancreas secrets a hormone called as insulin, which helps the cell in absorbing the glucose by reducing the blood sugar and providing glucose for energy. On falling of the sugar level pancreas releases a hormone called glucagon. This glucagon informs the pancreas about the presence of low sugar in blood, after which it releases the stored glucose, and helps in raising the blood sugar level. Alpha cell of pancreas produces glucagon.
The equation is glucose + oxygen carbon dioxide + water and energy is produced in the form of ATP.
Explanation:
Cellular respiration is a metabolic process in which glucose combines with oxygen to produce carbon dioxide and water with energy stored as ATP.
Glucose + Oxygen gas → Carbon dioxide + Water + energy in ATP
ATP is Adenosine TriPhosphate.
In the body, during cellular respiration, oxygen gas is inhaled and carried to sites in the body where food in form of glucose obtained from plant is broken down.
When food is broken down aerobically i.e in the presence of oxygen gas, carbon dioxide and water is produced and energy is stored in form of ATP.

False. The subunits are dependent on the cell itself, and they cannot survive on their own.
