Biology
1 answer:
sdas [7]3 years ago

Answer:

Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

One of the effects of the hormone secretin is to stimulate the release of bicarbonate ions into the duodenum, which neutralizes
Alecsey [184]

Answer: One consequence of neutralizing the pH in the intestine is that ENZYMES THAT CATALYZE THE HYDROLYSIS OF CARBOHYDRATES ARE ACTIVE.

Explanation: During digestion, partially digested food particles are transported from the stomach to the first part of the small intestines, that is, the duodenum. The food particles that are coming from the stomach are acidic due to the secretion of hydrochloric acid in the stomach. This acidity has to be removed when the food particles get into the duodenum, this is because the enzymes that are needed to break down carbohydrates in the duodenum can not work in acidic medium. Thus, in order for the  pancreatic amlayse enzyme to become active and to complete the break down of carbohydrate in the duodenum, the secretin hormone has to stimulate the release of bicarbonate that will neutralize the acidic partially digested food particles from the stomach.

jeka94
The patient can be subjected to intraoperative cholangiography wherein a stent in the bile duct will be placed and a radiopaque dye will be injected. X-rays will be taken. This is to locate the level of obstruction and to confirm if there is a common bile duct obstruction. In extracting stones, the surgeon can prefer doing an endoscopic retrograde cholangiopancreatography or ERCP and perform basket extraction of the common bile duct stone; or to surgically remove the sphincter of Oddi to allow easy passage of the stones.
