Mitosis doesn't bring genetic variety to species. Mitosis just copies DNA from one cell to a new one.
Mitosis has one cycle of cell division, in which cells replicate.
Meiosis has two cycles of cell division, in which sex cells are created.
These sex cells are not used to heal the body.
Inside our body, millions of nephrons in the kidney filter wastes in 2 steps. Each nephron has a glomerulus and a tubule. Waste filtering undergoes 2 steps:
First, fluid and waste pass through the glomerulus but, proteins, blood cells, and other large molecules are prevented from passing through.

Explanation:
There are two types of variables in a scientific experiment.
<u><em>Independent variable:</em></u> An independent variable can be described as the variable which is changed or can be controlled during the experiment. The effects of the independent variables on the dependent variable are tested.
In the scenario discussed in the question, amount of sleep will be independent variable as it is not dependent on any other factor.
<u><em> Dependent variable:</em></u> It is the variable which is being tested or measured due to changes in the independent variable.
In the scenario discussed in the question, the exam score will be the dependent variable as it will be dependent on the independent variable i.e amount of sleep.
