The endocrine system incorporates feedback mechanisms that maintain homeostasis. which of the following demonstrates negative feedback by the endocrine system? a) during labor, the fetus exerts pressure on the uterine wall, inducing the production of oxytocin, which stimulates uterine wall contraction. the contractions cause the fetus to further push on the wall, increasing the production of oxytocin. b) after a meal, blood glucose levels become elevated, stimulating beta cells of the pancreas to release insulin into the blood. excess glucose is then converted to glycogen in the liver, reducing blood glucose levels. c) at high elevation, atmospheric oxygen is scarcer. in response to signals that oxygen is low, the brain decreases an individual’s rate of respiration to compensate for the difference. d) a transcription factor binds to the regulating region of a gene, blocking the binding of another transcription factor required for expression.
