If a portion of the pancreas is surgically removed from a rat and the rat subsequently loses its appetite, one explanation is that the removed portion contains cells that secrete a chemical signal that somehow stimulates appetite. given this scenario, what type of chemical signaling is occurring? a) autocrineb) paracrinec) endocrined) neuroendocrine

The correct answer will be option-C

Explanation:

The pancreas is a small pear-shaped gland present in the abdomen and surrounded by the stomach.  The pancreas acts as both endocrine (secretes glucagon and insulin hormones) and exocrine (secretes digestive enzymes).

In the given question, the pancreatic part removed from the rat results in the loss of appetite as when insulin is not produced in the body results in uncontrolled sugar levels in the body. This leads to the loss of water from the body to the urine and as a result, the loss of appetite is observed.

Since the endocrine portion controls the insulin production therefore, option-endocrine is the correct answer.

thymine. in rna, thymine is replace by uracil

is this a psat question, if so do not cheat try your best.
