Answer:
The biosphere distributes water through the hydrological cycle that results from evaporation and perspiration.
Explanation:
The biosphere is the entire known ecosystem, which is formed by all organisms and living beings on the planet. The biosphere is known as the place where life is born; it is characterized by its evolution.
In the biosphere, the distribution of water is through the hydrological cycle in which it has a circular development, where water only moves from one place to another, in the same state or different physical states.
The cycle begins with the water falling into the biosphere; it is absorbed by plants, who need it to perform photosynthesis; in the process, the water passes to a vapor state. It is elevated to the troposphere where it condenses in clouds and finally falls to the biosphere in solid-state, and the cycle is repeated.
When the water fall to the surface, it can remain in it in a liquid state in a larger body of water, such as a river or a lake, or be absorbed by a living being. Still, the process will always end in its evaporation, condensation, and fall.

The Law of Equal Segregation states that during gamete formation, the two alleles at a gene locus segregate from each other; each gamete has an equal probability of containing either allele.
Answer:
Food gives you energy, but oxygen is needed to break down the food into pieces that are small enough for your cells to use This is known as cellular respiration and it is the process of oxidizing food molecules, like glucose, to carbon dioxide and water
