Q #2: Which of the following is the function of a totipotent cell?

A. Aids in the maturation of sex cells

B. Carries electrical impulses

C. Develops into any kind of cell

D. Fights infectious diseases

Answer Explanation

A totipotent cell is a type of stem cell that has the ability to develop into any kind of cell in the body, including the cells that make up the placenta and the umbilical cord. This means that a totipotent cell can generate a complete organism from a single cell. The only natural example of totipotent cells are the fertilized egg and the cells produced by the first few divisions of the egg. Totipotent cells are different from other types of stem cells, such as pluripotent cells, which can develop into any cell type except for the placenta and the umbilical cord, and multipotent cells, which can only develop into a limited range of cell types.
Q #3: Which of the following indicates the function of sodium bicarbonate released by the pancreas?

A. Sodium bicarbonate inhibits peristalsis.

B. Sodium bicarbonate stimulates the pyloric sphincter.

C. Sodium bicarbonate is a protease that digests carbohydrates.

D. Sodium bicarbonate neutralizes the acidity of chyme.

Answer Explanation

The pancreas releases sodium bicarbonate into the duodenum, the first part of the small intestine. The main function of sodium bicarbonate is to neutralize the acidity of chyme, the semi-digested food that comes from the stomach. By doing so, sodium bicarbonate creates a more alkaline environment that is suitable for the action of pancreatic enzymes. Sodium bicarbonate does not affect peristalsis, the rhythmic contraction of the intestinal muscles, nor does it stimulate the pyloric sphincter, the valve that controls the passage of food from the stomach to the duodenum. Sodium bicarbonate is not a protease, an enzyme that digests proteins, nor does it digest carbohydrates.
