1) 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 a type of cell division by which gametes, or the sperm and ova, reproduce.
4. Mitosis occurs in only a few cells of the body.
5. Meiotic division leads to cells that halve the original genetic material.

Answer:  3, 5

Explanation:  3. Meiosis is a special type of cell division by which diploid cells give rise to gametes (sperm and ova).

5. Meiosis creates two cells that contain half the genetic material of the parent cell.

2) 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

Answer:  2

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

3) The nurse educator is discussing human chromosomes with her students, and knows that the teaching has been effective when a student makes which statement?

1. “All humans have 48 chromosomes and 2 sex chromosomes.”
2. “Human chromosomes are shaped like a ‘Y’.”
3. “Humans have 46 chromosomes, 2 of which are the sex chromosomes.”
4. “Only certain body cells contain the chromosomes.”

Answer:  3

Explanation:  3. This is the correct answer. There are 22 pairs of similar cells and 2 sex chromosomes.

4) The nurse is teaching about reproduction, and explains that which of the following are the purposes of meiosis?

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 growth and development
5. Divide somatic cells into new cells with identical characteristics

Answer:  1, 2, 3

Explanation:  1. Meiosis is a special type of cell division by which diploid cells give rise to gametes (sperm and ova).

2. The cells contain half the genetic material of the parent cell–only 23 chromosomes–the haploid number of chromosomes.
3. During meiosis new combinations of cells are provided by the newly formed chromosomes; these combinations account for the wide variation of traits.

MNL LO:  1.4.2 Describe the function and structure of chromosomes and genes.

5) The nurse has completed a presentation on reproduction. Which statement indicates that the teaching has been successful?

1. “A male is born with all the sperm he will ever produce.”
2. “Females create new ova throughout their reproductive life.”
3. “Ova separate into two unequally sized cells.”
4. “Each primary spermatocyte divides into four haploid cells.”

Answer:  3

Explanation:  3. The first meiotic division produces two cells of unequal size with different amounts of cytoplasm but with the same number of chromosomes.
