Final answer:
The fetus begins to develop distinct male or female reproductive characteristics at two months of fetal age. The pancreas secretes sodium bicarbonate and is not responsible for breaking down carbohydrates with lipase. Fluid both fills and surrounds each cell in the body.
Explanation:
The fetus takes on either male or female reproductive characteristics, with differences beginning at two months of fetal age. So, the correct answer to this question would be option B. two months.
Regarding the pancreas and its functions, it secretes a variety of enzymes and substances that aid digestion and regulate blood sugar. Specifically, pancreatic juice is rich in the enzyme lipase that breaks down fats, not carbohydrates, and the enzyme *amylase* that breaks down carbohydrates. Additionally, it is true that the pancreas secretes sodium bicarbonate, which helps neutralize stomach acid entering the duodenum. Thus, the correct statement about the pancreas from the options provided is D. The pancreas secretes sodium bicarbonate.
Concerning cells and fluid, the correct statement is A. fills and surrounds each cell, meaning that fluid fills the intracellular space and also surrounds the cells in the extracellular space.
