The process of biofeedback begins when the subject

a.
reports their inputs with a computer
b.
receives feedback from their inputs
c.
has their biological impulses measured
d.
adjusts their responses according to feedback

The correct answer is C. The process of biofeedback begins when the subject has their biological impulses measured.

Explanation:

Biofeedback is a technique that is used to control the physiological functions of the human organism, through the use of a feedback system that informs the subject of the state of the function that he wants to control voluntarily.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.

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.
