What sentence best supports the statement that hormones are involved in the regulation of homeostasis? a. the hormone cortisol suppresses the immune system and is produced when the body is under stress. b. the hormone erythropoeitin increases the production of red blood cells when oxygen levels are low. c. the hormone oxytocin promotes labor contractions of the uterus during childbirth. d. the hormone melatonin induces sleep and its production is slowed by exposure to light.

B.  The hormone erythropoeitin increases the production of red blood cells when oxygen levels are low.

Explanation:

Homeostasis is the condition of an internal balanced environment. Lower oxygen availability deviates the body from homeostasis by reduced oxygen supply to body cells. However, homeostasis is restored by secretion of erythropoietin hormone from kidneys which in turn stimulate the production of RBCs. Increased red blood cells in blood compensate for lower oxygen levels and ensure sufficient oxygen supply to all body parts.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right

explanation:

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
