Statement 1: the process of diffusion does not require any input of energy.
Statement 2: Diffusion involves movement of particles from a region of higher concentration to a region of lower concentation.

Options

A. Both statements `1`and `2` are correct.
B. Statement `1` is correct but statement `2` is incorrect.
C. Statement `1` is incorrect but statement `2` is correct.
D. Both statements `1` and `2` are incorrect.

Answer

To analyze the two statements provided in the question, we can break down the information as follows:

### Step 1: Understand Statement 1
- **Statement 1:** "The process of diffusion does not require any input of energy."
- **Explanation:** Diffusion is a passive transport mechanism. It occurs naturally due to the random movement of particles and does not require any energy input (like ATP). This is because molecules move along the concentration gradient, from areas of high concentration to areas of low concentration.

### Step 2: Understand Statement 2
- **Statement 2:** "Diffusion involves movement of particles from a region of higher concentration to a region of lower concentration."
- **Explanation:** This statement accurately describes the process of diffusion. Molecules tend to move from areas where they are more concentrated to areas where they are less concentrated until equilibrium is reached.

### Step 3: Evaluate Both Statements
- Both statements are correct based on the definitions and principles of diffusion.
- Statement 1 correctly identifies that diffusion does not require energy.
- Statement 2 correctly describes the direction of movement in diffusion.

### Step 4: Conclusion
- Since both statements are correct, the answer to the question is that both Statement 1 and Statement 2 are correct.

### Final Answer
- Both statements are correct.
