Stem cells begin to transform into different types of cells in the human body in a process known as cell
a) differentiation
b) saponification
c) separation
d) speciation

Ans.

Stem cells are defined as cells that have ability to develop into different types of body cells. Stem cells undergo differentiation, a process in which one cell changes into another kind of cell, to form different types of specified cells from a single, unspecified, parent stem cell.

For example, a single hematopoetic stem cell differentiates to produce all kinds blood cells, such as red blood cells, white blood cells, and platelets.

Thus, the correct answer is 'option). differentiation.'

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.
