Answer

The process described is **C. mitosis**.

Solution

The process described in the problem is **C. mitosis**. Here's the reasoning: 1. **Chromosome Count**: The original cell has four chromosomes, and after the process, each daughter cell also has four chromosomes. This indicates that the chromosome number remains the same, which is characteristic of mitosis. 2. **Daughter Cells**: Mitosis results in two daughter cells that are genetically identical to the parent cell, maintaining the same chromosome number. 3. **Meiosis**: This process typically reduces the chromosome number by half, resulting in daughter cells with half the number of chromosomes (in this case, two chromosomes each if starting with four). 4. **Fertilization**: This is the fusion of two gametes (sperm and egg) and does not fit the description of a cell dividing into two daughter cells. Thus, the correct answer is **C. mitosis**.

Mind Expander

In this scenario, the process described is mitosis. During mitosis, a single cell divides to produce two identical daughter cells, each maintaining the same chromosome number as the original cell. So, if the original cell has four chromosomes, each daughter cell will also have four chromosomes, just like a perfect clone! If you're ever confused about when to use mitosis versus meiosis, remember: mitosis is all about growth and repair, while meiosis is for creating gametes (sperm and eggs) and reduces the chromosome number by half. Keep that distinction in mind, and you'll ace biology!
