The surface area/volume ratio is an important factor for one celled organisms. as a cell's volume grows, its surface area/volume ratio decreases, making it harder and harder to acquire enough nutrients via diffusion. because of this, cells stop growing after reaching a certain size. after reaching this state, a one celled organism is likely to a) enter into a spore state. b) continue to grow until it is so big it bursts. c) use mitosis to divide and create daughter cells. d) stop eating so that it shrinks and its surface area/volume ratio grows.

Answer

C. Use Mitosis to divide and create daughter cells.

Explanations

Single-celled organisms use mitosis to reproduce. Both growth and reproduction in single-celled organisms are mutually inclusive. When the cell’s volume increases, the ration of surface area to volume decreases creating challenges in acquisition of nutrients because there will be too much cytoplasm for a given amount of nuclear material  thus the cell divides by mitosis to reproduce daughter cells and the process begins again.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
