Microorganism protect themselves against harmful UV light and visible light by using Iron minerals around themselves.
The iron minerals have unique properties in that they block damaging UV radiation while yet allowing organisms to utilise the portion of sunlight required for photosynthesis. UV rays kill cells by damaging their DNA. Two molecules of thymine, one of the bases that makes up DNA, react when exposed to light. The thymine dimer that results is extremely stable. The cell cannot perform its usual tasks if cellular processes are interfered as a result of an inadequate repair or unrepaired damage of thymine dimer.

The correct answer is A. Hope this helps! ;)
Genetic variation happens when one organism in the population mates with a genetically different organism. Same species, different genetics such as color or height/weight.

The<u> ion concentration</u> in water molecules controls the amount of water in a compartment
The concentration of ions in a body of water determines the rate of diffusion and osmosis that occurs in a body of water contained within a body compartment. which has a direct impact on the amount of water that is held in any water body compartment.
Hence we can conclude that the ion concentration in water molecules controls the amount of water in a compartment.
