Answer:
In about the same place
Explanation:
The sun rises in the east and sets in the west each day because the earth rotates toward the east making a complete turn every 24 hours while the sun actually stays in its position at the center of our solar system. Therefore, as the earth spins clockwise, the sun reaches different parts of the earth at different times as the eastern part gets the sun rays first before it passes to the other parts of the earth.
Answer:
The correct option is a. The only endocrine gland that stores its hormone product extracellularly is <u>the thyroid.</u>
Explanation:
The thyroid gland is in the neck and is extremely fragile. The thyroid's function is to secrete thyroid hormones, these hormones have two functions: they regulate the growth and differentiation of cells and control the basal metabolic rate (rate at which the body's chemical reactions take place, temperature regulation)
The synthesis of thyroid hormones, is produced from 2 elements one contributed by the thyroid gland thyroglobulin and the other is a mineral that comes from the diet and is iodine. Both monoiodothyrosine and diiodotyrosinase concentrate in extracellular fluid and systemic circulation.
The most important thyroid hormone is thyroxine. It is synthesized in the thyroid gland from iodine, from the diet, and from the amino acid tyrosine. Its secretion is controlled by the pituitary gland through the negative feedback mechanism.
Answer:
A. will not change from generation to generation.
Explanation:
For a population in the Hardy-Weinberg equilibrium, allele frequencies do not change from generation to generation and remain constant. This occurs when:
-The population is large enough.
-Individuals of the population exhibit random mating
.
-No evolutionary force (natural selection, mutation, gene flow, etc.) is operative on the population.
Under these conditions, the allele frequencies of the population are not changed and the population is said to be in "Hardy-Weinberg equilibrium".
