Answer:
The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".
Explanation:
Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.

Answer:
ability to differentiate into other cell types during cell division i.e. totipotent nature
Explanation:
Stem cells are undifferentiated cells with the unique ability to develop into specialized cell types in the body during early life and growth through the process of cellular differentiation. When a stem cell divides, each new cell has the potential to either to remain a stem cell or become another type of cell with a more specialized function e.g muscle cell, red blood cell or a brain cell.
Stem cells provide new cells for the body as it grows, and replace specialized cells that are damaged or lost. This ability of stem cells to differentiate into a variety of cell types in an organism including embryonic tissue, is an important distinguishing factor. They have two unique properties that enable them do so:
1. They can divide over and over to produce new cells
2. As they divide, they can change into the other types of cell (cellular differentiation).
