Explanation:
Inflammation is the body defence system against various pathogens and include various components such as Immune cells and blood vessels. Inflammation occurs in a sequence of events.
- when a pathogen enters the cells macrophages produce the first response by phagocytizing the foreign body.
- The blood vessels dilated so more blood cells, oxygen and nutrients could reach at the site of pathogen and fight against it.
- Foreign pathogen is captured at that place so it can't mobilize to other part of the body.
- The more fighting cells are directioned at the site of infection
- The recruited phagocytic cells phagocytize the invaders pathogen and starts its degradation.
The fact that there is little diversity in the form of mc1r gene we can inferred that it is an that it is an advantageous trait to protect from extreme sun and lack of diversity is due to the negative selection.
- The MC1R gene give order for formation a protein called the melanocortin 1 receptor. This receptor plays very important role in normal pigmentation. The receptor is found on the surface of melanocytes, these cells secrete a pigment called melanin. Melanin is that the pigment that gives skin, hair, and eyes their colour.
- Negative selection works to get rid of deleterious alleles from a population in another term that describes this is often “purifying selection.”
- Positive selection leads to directional selection. Positive selection for a beneficial allele can increase the frequency of neutral variants neighbouring the beneficial allele; such genetic hitchhiking may end in a large area of homozygosity (i.e., loss of diversity during a large area of a chromosome) due to a highly advantageous mutation and is referred to as a selective sweep.

Fruits, vegetables, spices, cereals, Wood, Fibres, Cotton, perfumes, dyes, and most importantly medicines.
Explanation:
Plants play a major role in the preparation of several useful drugs and antibiotics.
Approximately the size of bacteria will grow to 128 bacteria if 64 bacteria will reproduce after 35 minutes. They will only reproduce once in <span>35 minutes. </span><span>
</span><span>A bacteria will usually reproduce or grow by dividing into two this is called a binary fission. On the above situation, 64 bacteria will reproduce also a 64 bacteria which has the total of 128. </span>
