Explicación
## Step 1The first question asks for two parts of meiosis that are similar to mitosis. Both meiosis and mitosis are forms of cell division, and they share some common stages. The two stages that are similar in both processes are:### **Prophase**: In both mitosis and meiosis, chromosomes condense and become visible. The nuclear envelope begins to break down, and spindle fibers form.### **Metaphase**: In both processes, chromosomes align at the metaphase plate (the cell's equatorial plane).## Step 2The second question asks to identify whether each process occurs during mitosis, meiosis, or both. ### **A. Sister chromatids separate**: This occurs in both mitosis and meiosis.### **B. Haploid cells are formed**: This only occurs in meiosis.### **C. Cell division occurs just once**: This only occurs in mitosis.### **D. Homologous chromosomes pair**: This only occurs in meiosis.### **E. 4 haploid cells are the final result**: This only occurs in meiosis.### **F. Crossing over occurs**: This only occurs in meiosis.### **G. Cell division occurs twice**: This only occurs in meiosis.### **H. Replicated chromosomes line up in the middle**: This occurs in both mitosis and meiosis.### **I. 2 diploid cells are the final result**: This only occurs in mitosis.
