Which one is the correct graph for arithmetic growth?

Options

A.
B.
C.
D.

Answer

To determine the correct graph for arithmetic growth, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Arithmetic Growth**:
- Arithmetic growth refers to a type of growth where a fixed amount is added at regular intervals. In biological terms, this often involves cell division where one cell divides to produce two cells, but only one continues to divide while the other differentiates.

2. **Identify Characteristics of Arithmetic Growth**:
- In arithmetic growth, the increase is constant over time. This means that if you were to plot this growth on a graph, the increase in size or number of cells would be uniform.

3. **Graph Representation**:
- The graph of arithmetic growth is represented as a straight line. This is because the growth occurs at a constant rate, leading to a linear increase over time.

4. **Analyze Given Options**:
- Option A: A linear curve (correct for arithmetic growth).
- Option B: A sigmoid curve (indicative of exponential growth).
- Option C: A constant line (indicating no growth).
- Option D: A decreasing line (indicating negative growth).

5. **Select the Correct Option**:
- Based on the analysis, the correct graph for arithmetic growth is represented by Option A, which shows a linear increase.

### Final Answer:
The correct graph for arithmetic growth is **Option A**, which is a linear curve.
