Which of the following would accompany a high-fat meal moving through the digestive system? The release of gastrin, which triggers the liver to release bile
The release of gastrin, which triggers the stomach to release pepsin
The release of secretin, which triggers the liver to release bile
The release of secretin, which triggers the stomach to release pepsin

Answers

The answer is The release of secretin, which triggers the liver to release bile.

Secretin is the hormone released from the duodenum. It signals the secretion of bile in the liver. Bile helps digestion of lipids in the stomach.
Through the process of elimination:
- Pepsin is a hormone that breaks down proteins to the smaller peptides. So, pepsin does not breaks down lipids of high-fat meal.
- Gastrin is a hormone that triggers the gastric glands to secrete hydrochloric acid and pepsinogen, inactive form of pepsin.

You perform a spread plate to determine the bacterial population in a batch liquid media. You plate 0.1ml of a 10-5 dilution. You incubate the plate and count 10 colonies (cfu). What is the bacterial population in cfu/ml of the stock (undiluted) culture? 10 million colonies 1 million colonies 100 million colonies

Answers

Answer: 10 million colonies

The volume of media used is 0.1ml and the concentration diluted to 10^-5, so the actual volume used would be: 0.1ml * 10^-5= 1ml * 10^-6

The media shows 10 colonies. The number of colonies per volume would be: 10 cfu/ (1ml * 10^-6)= 10* 10^6 cfu/ml= 10 million cfu/ml
