Answer:
C. Cholesterol
Explanation:
Cholesterol maintains the fluidity of the cell membrane and thereby, regulates its function.
Bile acids are derived from cholesterol which serves as their precursor. For example, Taurocholic acid is a polar derivative of cholesterol. Bile acids serve in the absorption of fatty acids, glycerol, and fat-soluble vitamins as these compounds are non-polar in nature.
Vitamin D is produced when the derivative of cholesterol, 7-dehydrocholesterol undergoes photolysis in skin cells in presence of sunlight.

Decreasing first and then growing happening to the population because at every year 10.20 percent population is growing.
<h3>
How can you figure out a population's growth rate when there are births and deaths?</h3>
The net reproduction rate (r) is computed as follows: r = (births-deaths)/population size, or simply multiply by 100 to get in percentage terms. Because the population has grown so much, many more people have been added. When a population grows at a steady rate year after year, this is referred to as exponential growth.
Migration is the the number of immigrants minus the number of emigrants over a given time period, divided by the number of person-years lived by the receiving country's population during that time period. It is calculated as the number of net migrants per 1,000 people.

There are choices for this question namely:
<span>right primary
right secondary
left secondary
left primary
</span>
The correct answer is "right primary" or the right main bronchus. Anatomically, the right main bronchus has a larger diameter and a steeper angle (to compensate for the location of the liver). When a foreign body is accidentally aspirated, most commonly, it will lodge on the right main bronchus; especially in children.
Answer:
Birds and bats have homologous limbs because they are both ultimately derived from terrestrial tetrapods, but their flight mechanisms are only analogous, so their wings are examples of functional convergence.
