Answer:
The importance of mitosis lies in its condition of cellular reproduction par excellence, characteristic of the vast majority of life forms that currently populate the Earth.
Explanation:
Mitosis is the cellular process by which two identical nuclei are produced in preparation for cell division. In general, mitosis is immediately followed by the equitable distribution of the cell nucleus as well as the rest of the cellular content in two daughter cells.
We all start being a cell. That is quite difficult to imagine, but it is true. And now there are about a hundred billion cells in each of our bodies, and each one has to carry the complete set of DNA instructions. That means that when cells divide, all that has to be copied by some process. And that is mitosis, where each chromosome has to be converted into a pair, and then they have to separate properly so that each of the daughter cells receives a complete set.
When it comes into contact with a host cell, a virus can insert its genetic material into its host, literally taking over the host's functions. An infected cell produces more viral protein and genetic material instead of its usual products. Some viruses may remain dormant inside host cells for long periods, causing no obvious change in their host cells (a stage known as the lysogenic phase). But when a dormant virus is stimulated, it enters the lytic phase: new viruses are formed, self-assemble, and burst out of the host cell, killing the cell and going on to infect other cells. The diagram below at right shows a virus that attacks bacteria, known as the lambda bacteriophage, which measures roughly 200 nanometers
Answer:
A fast increase in blood sugar causes a rapid increase in insulin, which is the hormone responsible for allowing glucose to enter cells. High insulin levels cause glucose levels to quickly fall, which can then cause you to feel hungry again, prompting you to take in more calories.

Answer:
D
Explanation:
Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.
