Answer:
Biosphere is affected directly by the change in the hydrosphere in a natural way for example: the rain that falls from cloud and again the cloud forms by the evaporation of water from the ocean.
Explanation:
- Rain (hydrosphere) falls into the atmosphere from clouds forming the river water and streams in the biosphere.
- Plants and animals are dependent over this rain water for their survival in the form of drinking water for their growth.
- Water then evaporates from the rivers and oceans forming clouds when water vapor condenses.
- In this way living organism are highly affected by the natural process occurred in the hydrosphere.

nerves. The fovea is responsible for the higher visual acuity 20/20 vision. It
is the region if the retina that is depressed and has little blood vessel
supply to avoid dispersion of light. While it only comprises 1% of the
retina, it makes up 50% of brain’s visual cortex. </span>
<span>Meiosis in simple terms is the process by which gametes (sperm and egg) fuse together to produce a fertilised egg. Haploid is a word that refers to how many chromosomes a certain cell has. In this case the gametes have a haploid number of chromosomes, which is half the number a normal cell has. A normal cell has a diploid number of chromosomes. So in meiosis the two gametes come together with their hapoid number of chromosomes each to create an egg that has a diploid (standard) number of chromosomes.</span>
