Which of the following is an incorrect statement about the stress response?
a. the anterior pituitary secretes adrenocorticotropic hormone (acth)
b. the adrenal medulla secretes cortisol
c. the hypothalamus secretes corticotropin-releasing hormone (crh)
d. the posterior pituitary does not play a major role in the stress response

b. The adrenal medulla secretes cortisol

Explanation:

Under stress conditions, anterior pituitary gland secretes adrenocorticotropic hormone (ACTH) which in turn stimulates secretion of glucocorticoids from the adrenal cortex. One of the main glucocorticoid hormone is cortisol.

The cells of the zona fasciculata of the adrenal cortex secrete cortisol. Cortisol increases the breakdown of proteins and lipids to facilitate the release of more energy to fight the stress conditions.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
