### Question 1 - PART A
**Which of these would best fill in the chart for "B"?**
The options are:
- A: 0 chromosomes
- B: 23 chromosomes
- C: 46 chromosomes
- D: 69 chromosomes
**Best Answer: B (23 chromosomes)**
**Explanation:** If a normal cell has 46 chromosomes, this number would be halved during the process of meiosis (the type of cell division that produces gametes), resulting in 23 chromosomes for each gamete (sperm or egg).
### Question 2 - PART B
**Which of these best describes why your answer Part A must occur every time?**
The options are:
- A: Mitosis triples the number of chromosomes to give new cells a better chance of survival.
- B: Deletion of chromosomes through mitosis is essential to maintain a species in the future.
- C: Mitosis forms sperm and eggs which must have half the number of chromosomes as the original.
- D: In order to maintain genetic continuity, it is important that mitosis create new cells with the same number of chromosomes as the original cell.
**Best Answer: C (Mitosis forms sperm and eggs which must have half the number of chromosomes as the original.)**
**Explanation:** Meiosis (not mitosis) is the process that forms gametes (sperm and eggs), leading to cells with half the number of chromosomes (23) necessary for sexual reproduction. This is essential to ensure that when two gametes fuse during fertilization, the resulting zygote has the correct diploid number of chromosomes (46). The statement in option D is relevant to mitosis but incorrect in the context of forming gametes.
