The best answer is C
The process by which a cell divides is called mitosis. It results in two daughter cells that are genetically identical to each other and to the original cell.
Multicellular organisms, depend on mitosis for growth and repair. Organisms repair some of their tissues using mitosis to regenerate new cells. Not all cells undergo mitosis at the same rate. In man, brain cells are much more difficult to regenerate than cheek cells which are constantly being replaced.
When a cell is not dividing, the DNA is loosely spread throughout the nucleus in a threadlike form called chromatin.
A redshift is when light or other electromagnetic radiation from an object moves away from the observer.
SHELL products are derived from invertebrates.
