Application of concepts and technique of physics and chemistry in understanding biology is called

Options

A. Functional biology
B. Environemental biology
C. Evolutionary biology
D. Reductional biology

Answer

To solve the question regarding the application of concepts and techniques of physics and chemistry in understanding biology, we need to analyze the given options one by one.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the application of physics and chemistry concepts in biology.

2. **Analyzing the Options**:
- **Option A: Functional Biology**: This refers to the study of the functions of biological systems, particularly in a comparative manner between plants and animals. It does not specifically involve the application of physics and chemistry techniques.
- **Option B: Environmental Biology**: This field focuses on ecological interactions and environmental issues. It does not primarily deal with the application of physics and chemistry in biology, so this option is also incorrect.
- **Option C: Evolutionary Biology**: This branch studies the processes of evolution, natural selection, and the diversity of life. While it involves biological concepts, it does not specifically apply physics and chemistry techniques, making this option incorrect as well.
- **Option D: Reductional Biology**: This term refers to the approach of understanding biological phenomena by breaking them down into their constituent parts, often using techniques from physics and chemistry. This option aligns perfectly with the question.

3. **Selecting the Correct Answer**: After analyzing all the options, it is clear that the correct answer is **Option D: Reductional Biology**.

### Final Answer:
The application of concepts and techniques of physics and chemistry in understanding biology is called **Reductional Biology**.
