Which of the following are macronutrients?
A. Sodium, potassium, carbohydrates, lipids, and proteins
Sodium, potassium, carbohydrates, lipids, and proteins: Sodium and potassium are micronutrients, not macronutrients.
B. Carbohydrates, lipids, proteins, and water
Carbohydrates, lipids, proteins, and water: Carbohydrates, lipids, and proteins are macronutrients, but water is not classified as a macronutrient. This option is partially correct but includes water, which is not a macronutrient.
C. Nucleic acids, carbohydrates, lipids, and proteins
Nucleic acids, carbohydrates, lipids, and proteins: Nucleic acids are not classified as macronutrients; carbohydrates, lipids, and proteins are.
D. Carbohydrates, lipids, and proteins, but not water
Carbohydrates, lipids, and proteins, but not water: Carbohydrates, lipids, and proteins are macronutrients, and excluding water is correct since water is not a macronutrient.

Pepsinogen is produced by______________ and is activated by__________
A. chief cells; hydrochloric acid (HCI): parietal cells
Chief cells; hydrochloric acid (HCl); parietal cells: Pepsinogen is produced by chief cells, and it is activated into pepsin by hydrochloric acid (HCl) secreted by parietal cells.
B. chief cells; carbonic anhydrase (CAH); parietal cells
Chief cells; carbonic anhydrase (CAH); parietal cells: Chief cells produce pepsinogen, but it is not activated by carbonic anhydrase. Instead, it is activated by HCl.
C. parietal cells; carbonic anhydrase (CAH); chief cells
Parietal cells; carbonic anhydrase (CAH); chief cells: Pepsinogen is produced by chief cells, not parietal cells, and its activation involves HCl, not carbonic anhydrase.

When does an ovum finish meiosis?
A. While in a secondary follicle
While in a secondary follicle: The ovum completes meiosis only after fertilization, not while in a secondary follicle.
B. While in a primary follicle
While in a primary follicle: The ovum is arrested in prophase I of meiosis while in a primary follicle. Meiosis is not completed until fertilization.
C. During fertilization
During fertilization: The ovum completes meiosis II during fertilization, which is when the second meiotic division is completed.
D. During implantation
During implantation: Meiosis is not completed during implantation. It is completed at fertilization.
