Over small distances substances move by (A)____ and by (B)____ supplemented by (C)_____

Answer

To answer the question, "Over small distances substances move by (A)____ and by (B)____ supplemented by (C)____," we can break it down step by step.

### Step 1: Identify the first method of movement (A)
- **Answer**: The first method of movement over small distances is **diffusion**.
- **Explanation**: Diffusion is the process where substances move from an area of high concentration to an area of low concentration. This is a passive process and occurs at the molecular level.

### Step 2: Identify the second method of movement (B)
- **Answer**: The second method of movement is **cytoplasmic streaming**.
- **Explanation**: Cytoplasmic streaming, also known as cyclosis, refers to the movement of the cytoplasm within the cell. This movement helps distribute nutrients, organelles, and other substances throughout the cell.

### Step 3: Identify the supplementary method of movement (C)
- **Answer**: The supplementary method of movement is **active transport**.
- **Explanation**: Active transport is the process of moving substances against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires energy, usually in the form of ATP.

### Final Answer
Putting it all together, the complete answer is:
Over small distances substances move by (A) **diffusion** and by (B) **cytoplasmic streaming** supplemented by (C) **active transport**.
