1. **How many photons does it take to fully reduce one molecule of NADP* to NADPH?**
- The correct answer is **2**. It typically takes two photons to fully reduce one molecule of NADP+ to NADPH during the light reactions of photosynthesis.
2. **At which stage of meiosis are sister chromatids separated from each other?**
- The correct answer is **anaphase II**. During anaphase II of meiosis, sister chromatids are pulled apart to opposite poles of the cell.
3. **Imagine a cell can perform exocytosis, but only minimal endocytosis. What would happen to the cell?**
- The correct answer is **The plasma membrane would increase in size over time.** If the cell is primarily performing exocytosis without sufficient endocytosis, it would continuously add membrane to its surface, leading to an increase in plasma membrane size.
