Answer:
c) adrenocorticotropic hormone (ACTH).
Explanation:
A tropic hormone is defined as the hormone which is secreted from one gland and acts on another gland. ACTH is released by anterior portion of our pituitary gland during the condition of biological stress. After it is released, it acts on adrenal gland so that adrenal gland could secrete another hormone named as cortisol (steroid hormone). In response to stress, cortisol increases blood sugar level, elevates brain's use of glucose etc. so as to counter stressful situation.
Apart from this cortisol also helps in regulating our metabolism, reduces inflammation and controls salt and water balance.
Because the galaxy is so huge, astronomers had to come up with a unit of measurement able to convey such incredible distance.
If organisms a and b both possess wings and are the only extant organisms that possess wings, then we can hypothesise that the current generation of flight organisms are the descendants of a, b, or both a and b, and that the wing trait first originated in these two organisms.
Since the trait for flight first evolved in a and b, it must have been carried forward into the future generations of species that must have evolved by various evolutionary processes like speciation, acting on a and b.
