Find the correct match in the following:

Options

A. Viruses are smaller in size ranging from 20-400 nm and bacteria is larger in size , around 1000 nm.
B. Origin of solar system : 20 billion years ago and organic of universe system: 50 billion years ago
C. Founder effect operates in a large population and gene flow operates in a small population
D. Deep veins are located on the surface of the skin

Answer

To solve the question of finding the correct match among the given statements, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the first statement:**
- **Statement:** "Viruses are smaller in size range from 20 to 400 nm and bacteria is larger in size around 1000 nm."
- **Evaluation:** This statement is correct. Viruses typically range from 20 to 400 nanometers in size, while bacteria are generally larger, averaging around 1000 nanometers.

2. **Analyze the second statement:**
- **Statement:** "Origin of solar system was 20 billion years ago. But the evolution of the solar system is 4.5 billion years ago."
- **Evaluation:** This statement is incorrect. The origin of the solar system is estimated to be about 4.5 billion years ago, not 20 billion years.

3. **Analyze the third statement:**
- **Statement:** "The founder's effect operates in a large population. And the gene flow operates in a small population."
- **Evaluation:** This statement is incorrect. The founder effect occurs in small populations, while gene flow typically occurs when individuals move between large populations.

4. **Analyze the fourth statement:**
- **Statement:** "Our deep veins are located in the surface of skin."
- **Evaluation:** This statement is incorrect. Deep veins are located deeper within the body, particularly in the legs, and are not found at the surface of the skin.

5. **Conclusion:**
- The only correct statement is the first one regarding the size of viruses and bacteria. Therefore, the correct match is the first option.

### Final Answer:
The correct match is: **1. Viruses are smaller in size range from 20 to 400 nm and bacteria is larger in size around 1000 nm.**
