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.

c. would be the answer : )

explanation:

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
