The nurse is preparing a class on reproduction. What is the cell division process that results in two identical cells, each with the same number of chromosomes as the original cell called?
 
  1. Meiosis
  2. Mitosis
  3. Oogenesis
  4. Gametogenesis

Question 2

The nurse is teaching about reproduction, and explains that the purposes of meiosis are to: Note: Credit will be given only if all correct and no incorrect choices are selected. Select all that apply.
 
  1. Produce gametes.
  2. Reduce the number of chromosomes.
  3. Introduce genetic variability.
  4. Produce cells for tissue repair.
  5. Divide somatic cells into new cells with identical characteristics.

Answer to Question 1

2
Explanation: 2. Mitosis results in the production of diploid body (somatic) cells, which are exact copies of the original cell.

Answer to Question 2

1,2,3
Rationale 1: In the production of reproductive cells (gametes), there is a reduction of chromosome numbers by half (from diploid 46 to haploid 23), so that when fertilization occurs, the normal diploid number is restored. This introduces genetic variability.
Rationale 2: In the production of reproductive cells (gametes), there is a reduction of chromosome number by half (from diploid 46 to haploid 23), so that when fertilization occurs, the normal diploid number is restored. This introduces genetic variability.
Rationale 3: In the Production of reproductive cells (gametes), there is a reduction of chromosome number by half (from diploid 46 to haploid 23), so that when fertilization occurs, the normal diploid number is restored. This introduces genetic variability.
Rationale 4: The purpose of mitosis is to produce cells for growth and tissue repair. Cell division is characteristic of all somatic cells.
Rationale 5: The purpose of mitosis is cell division to create cells having the characteristics of all somatic cells.
