D. Biology. In forensics, they use DNA-related evidence, and DNA relates to biology.
Tropopause is the boundary between the troposphere and stratosphere.
Explanation:
- Tropopause marks the transition region between troposphere and stratosphere.
- As we move up from the Earths surface , the temperature gets colder but when we reach the tropopause the temperature becomes constant and the temperature does not fall further.
- It is at a height of about 9Km at the polar region while at a height of 17 Km at the equitorial region.

❖ Prokaryotic DNA isn't surrounded by a membrane like Eukaryotic DNA is. The DNA in a prokaryotic cell floats around freely.
