All of the following are regulated by the medulla except a. breathing b. swallowing and vomiting c. coughing and sneezing d. the fight-or-flight response

The answer is; D.

The medulla controlled most autonomic process of the body. The fight-or-flight response, though also autonomic, is controlled by the amygdala that triggers the hypothalamus that initiates a cascade of biochemical processes that causes the adrenal gland to release adrenaline. The medulla is usually involved in breathing, swallowing, and other cardiac and respiratory vasomotor functions. Medulla is part of the hindbrain.

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.

b is dominant over the allele for the white fur.
