Question 2

The nurse is explaining the difference between meiosis and mitosis. Which statements would be best? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply.
 
  1. Meiosis is the division of a cell into two exact copies of the original cell.
  2. Mitosis is splitting one cell into two, each with half the chromosomes of the original cell.
  3. Meiosis is the process by which gametes, or the sperm and ova, reproduce.
  4. Mitosis occurs in most of the cells of the body.

Answer to Question 1

1, 2, 4
Explanation: 1. Cervical mucus at ovulation becomes thin, clear, watery, and more alkaline, making it more favorable to spermatozoa.
2. Estrogen peaks just before ovulation in the proliferative phase of the menstrual cycle.
4. The cervical mucosa pH increases from below 7 to 7.5 at the time of ovulation.

Answer to Question 2

3,5
Rationale 1: Meiosis creates two cells that have half of the chromosomes of the original cell.
Rationale 2: Mitosis creates two cells that are exact copies of the original cell.
Rationale 3: Both sperm and ova are created through meiosis.
Rationale 4: Mitosis is how the majority of cells reproduce, so that the new cells have the same structure and function as the original.
Rationale 5: Meiosis creates two cells that have half of the chromosomes of the original cell.
