Exponential growth occur in

Options

A. yeast
B. asexual reproduction
C. bacteria
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understanding Exponential Growth**:
- Exponential growth refers to an increase in number or size at a constantly growing rate. This means that as time progresses, the quantity increases rapidly.

2. **Identifying the Context**:
- The question asks in which scenarios exponential growth occurs. The options provided are:
- A) Yeast
- B) Asexual reproduction
- C) Bacteria
- D) All of these

3. **Analyzing Each Option**:
- **Option A: Yeast**: Yeast reproduces asexually through budding, which allows for rapid population increase. Therefore, yeast can exhibit exponential growth.
- **Option B: Asexual Reproduction**: Asexual reproduction itself is a process that often leads to exponential growth, as organisms can reproduce quickly without the need for a mate.
- **Option C: Bacteria**: Bacteria also reproduce asexually through binary fission, leading to rapid population increases. Hence, bacteria can also show exponential growth.

4. **Conclusion**:
- Since all three options (yeast, asexual reproduction, and bacteria) are capable of exhibiting exponential growth, the correct answer is **D) All of these**.

**Final Answer**: D) All of these
