ONLY ANSWER IF YOURE AN EXPERIENCED FISH KEEPER<br> is my female swordtail pregnant?
LenKa [72]

Answer:

I don't know what your fish looks like but I will try my best :)

To accommodate the developing eggs, the mother's body expands, becoming deeper and broader. A few days before delivery, she develops a bulge below the gills, her outline becoming fairly square in this region, while the gravid spot has enlarged its area. The female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.

Hormones or paracrines that inhibit gastric secretion include ________.
enot [183]

Answer:

This question lacks options, options are:

A) histamine

B) gastrin

C) secretin

D) ACh

The correct answer is C.

Hormones or paracrines that inhibit gastric secretion include <u>secretin </u>.

Explanation:

Hormones pass into the blood that waters the digestive system, go to the heart, circulate through the arteries and return to the digestive system, where they stimulate the production of digestive juices. The hormones that control digestion are gastrin, secretin and cholecystokinin. Secretin is stimulated by intestinal acid at the duodenal level. Its effect inhibits gastric acid secretion, prostaglandin secretion and via somatostatin release. It decreases gastric emptying and stimulates bile and pancreatic bicarbonate secretion.
