Which of the following could be the goal of a negative feedback loop a. to release hormones b. to return a substance to a normal level c. to enhance an action of a stimulus d. to signal receptors to take in sensory information

Answer choice B.

Negative feedback is when the system is always returning to the same consistant conditions.

A good example of negative feedback would be body temperature (always returns to normal, despite small flunctuations).

Positive feedback always progresses completely. Like growth (once you grow, you stay that way) & pregnancy (fetus is constantly growing and then undergoes childbirth, a forward process).

Hope that helps!

Since a female is both xx chromosome and the male passes down the x chromosome, than the offspring would be female since a female is xx.
