<span>Pepsin is an enzyme that breaks down proteins into amino acids in the stomach (where the pH is 1-3). Pepsin needs to be in an acidic environment to be activated. The optimum temperature is between 30 oC and 40 oC because the average human body temperature is 37 oC. The optimum pH is the acidic one because your stomach has an acidic pH.</span>
Plastics clearly constitute an important component of the range of materials used in modern society. Almost all aspects of daily life involve plastics or rubber in some form or the other. ...

Explanation:
Physical weathering is the disintegration of rocks into smaller chunks in nature.
Water is one of the agents that causes physical weathering.
- during periods of low temperature especially the summer, water usually collects within rock cavities.
- When temperature drops, the water freezes and expands.
- Periodic freezing and thawing of ice leads to physical weathering.
- Also, in tropical regions, alternate wetting and drying of rocks occur.
- When a rock is wet, it absorbs more water and it volume expands.
- Drying occurs and it loses the water.
- This continuous process leaves cracks in rock.
