Answer
Use Mitosis to divide and create daughter cells.
Explanations
Single-celled organisms use mitosis to reproduce. Both growth and reproduction in unicellular organisms are mutually inclusive. When the cell’s volume grows, the ratio 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.
Answer: D.) It allows water to resist freezing and thawing cycles.
The ability of the water molecule to absorb and retain heat is called as heat capacity of water, because of this property the temperature of water remains the same for long, irrespective of the external environment. It allows water to resist freezing and thawing cycles because water molecules will resist change in it's temperature. This temperature regulation will prevent instant heating and cooling, hence, will provide suitable environment for the survival of marine organisms.
