Answer:
Option D
Explanation:
In 1972, the fluid mosaic model was proposed by S. J. Singer and G. L. Nicolson to describe the structure of the plasma membrane found I living cells. The model describes the plasma membrane to possess components including phospholipid, proteins and cholesterol.
The phospholipid is arranged in two layers comprising of glycerol, two fatty acids and a phosphate group. The fatty acids which forms the tail are hydrophobic (water-fearing) while the phosphate group is water-loving (hydrophobic) giving the plasma membrane an AMPHIPATHIC nature. The other component as proposed by the model are membrane proteins and cholesterol, all responsible for the fluidity of the membrane.

Type 2 diabetes is a disease in which blood sugar levels are above normal. High blood sugar is a major cause of heart disease, kidney disease, stroke, amputation, and blindness. In 2009, diabetes was the seventh leading cause of death in the United States.
<u>Answer:</u>
Although statements are not given in the question, we could make the most possible deduction as follows:
The allele for purple flowers is dominant whereas allele for white flowers is recessive.
<u>Explanation:</u>
According to the question,
- Purple flower plant was crossed with white flower plant.
- All offsprings have purple flowers.
Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
Answer:
i think it's the double helix
Explanation:
Proteins also have structural or mechanical functions, such as actin and myosin in muscle and the proteins in the cytoskeleton<span>, which form a system of scaffolding that maintains cell shape. Other proteins are important in cell signaling, immune responses, </span>cell adhesion<span>, and the cell cycle. hope that helped</span>
