How would you explain why bicarbonate and digestive enzymes respond differently in two of the variables in figure 30-8

Answer:

1. Response to hydrochloric acid

HCO3- also known as bicarbonate, is a polyatomic anion, a byproduct of the body's metabolism and one of the two main components of the pancreatic juice. A base excreted by the epithalial cells of the pancreas, bicarbonate has the critical function of neutralizing the hydrochloric acid found in the gastric juice. This is why the pancreatic juice contains mostly bicarbonate when this acid is present.

2. Response to fat

When fats are predominant, the second component of the pancreatic juice, the digestive enzymes are abundant. This broad group of biological catalysts have the role of reducing all digestible macromolecules (such as fats) into forms that can be absorbed by the body. They are critical to the digestive process.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
