Answer:
from the image:
1. eight
2. four
3. less than
Explanation:
from the data given...
n= 4
where n= # of genes
&, the extreme # of segments= 
Genes, which make up a genotype are instructions for encoding a phenotype, expressed as proteins in translation.
...one gene may have 2 alleles
An allele is an alternate form of a particular gene. Genes can have multiple alleles, but in this case...
∴4 genes= 4 × 2=<u> </u><u>8 segments</u>
<u />
<u>Thus, each allele gives </u> 
= <u>1 segment</u>
<u></u>
<u></u>
I am certain that placing pressure on a cut will constrict blood vessels manually, and encourages vascular spasms.
Vascular spasms are sudden, brief tightening of the muscle cells inside the walls of a blood vessels. It is the first response as the blood vessels constrict to allow less blood to be lost. In the second step, platelet plug formation, platelet stick together to form a temporary seal to cover the break in the vessel wall, the third step is the coagulation or blood clotting.
Answer: helps cool the body
removes waste chemicals through pores in the skin
Explanation:
Perspiration is a natural biological process that occurs in an mammals including human beings. Perspiration is required to maintain the homeostasis of the body. Homeostasis is the condition of maintenance of stable internal environment of the body with respect to the changes occurring in the external environment. Perspiration is also called as sweating when the body is exposed to heat it secrete sweat in order to provide coolness to the body. As the sweat contents are evaporated in the exposure of air. The sweat contents are emerge out by the pores present on the skin surface. The sweat consists of chemicals like aminoacids, salts and excess of water. Therefore, sweat removes the waste chemicals through the pores of the skin.
White blood cells structure are quite varied, and different kinds have different functions. These are a few options:
1. The flexibility of the plasma membrane allows bacteriophage and increases mobility in pursuit of invaders.
2. Beta cells put out chemical antigens to eliminate invaders chemically.
3. Various white cells display proteins on their plasma surfaces to communicate the composition of the pathogen.
4. White cells (unlike red blood cells) have a nucleus, which allows the synthesis of new chemicals in response to various invaders.
5. White<span> blood cells tend to have a higher surface to volume ratio than other cells because the are more amorphous. That would lead to a relative increase in the plasma membrane, which contains receptors for identifying.antigens. T</span><span>he white blood cells may be more receptive to detection of antigens due to a higher surface-to-volume ration.</span>
