The correct Answer is:
To determine how many chromosomes are present in a haploid cell for an animal that has somatic cells with 18 chromosomes, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Definition of Somatic and Haploid Cells**: - Somatic cells are the body cells of an organism, which are diploid (2N), meaning they contain two sets of chromosomes, one from each parent. - Haploid cells (N) are cells that contain only one set of chromosomes. In animals, these are typically the gametes (sperm and egg cells). 2. **Identify the Number of Chromosomes in Somatic Cells**: - The problem states that the somatic cell of the animal has 18 chromosomes. This means that the diploid number (2N) is 18. 3. **Calculate the Haploid Number**: - To find the haploid number (N), we divide the diploid number by 2: \[ N = \frac{2N}{2} = \frac{18}{2} = 9 \] - Therefore, the haploid cell will have 9 chromosomes. 4. **Conclusion**: - A haploid cell for this animal would contain 9 chromosomes. ### Final Answer: A haploid cell for this animal would have **9 chromosomes**. ---
