DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
DNA replication needs to occur because existing cells divide to produce new cells. Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions.
With out DNA replication no individual can survive.

Answer:
<em>Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, </em><em>organelles serve specific functions to keep a cell alive.</em>
<em>Explanation:</em>
Answer:
The distribution of chloroplasts in each algae cell was approximately the same.
The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.
Explanation:
Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.
The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
