Pepsin, an enzyme that is found in the stomach of humans, functions in breaking down proteins. It is denatured as it travels to
AnnZ [28]

Answer:

A. pH

Explanation:

Denaturation of proteins is a protein whereby the protein molecule loses its primary structure and ultimately its physical functioning as a result of factors including pH, temperature or concentration of chemicals. Based on this definition, it is visible that denaturation of proteins can be caused by these three factors: pH, chemical and temperature.

However, in this case of PEPSIN enzyme, which is a proteinous molecule produced in the stomach of humans and functions in breaking down proteins, its denaturation occurs as it moves along the digestive tract to the intestines. This is as a result of the changes in pH in the digestive tract.

The pH of the stomach where pepsin is produced is acidic i.e. <3.0. However, as one moves towards the intestine, the pH increases, which is unfavorable or considered harsh for the pepsin enzyme. Hence, it gets denatured.

What evidence do paleobotanists look for that indicates the movement of plants from water to land?
attashe74 [19]

The evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.

<h3>What are some adaptations of plants on land compared to water?</h3>

Plants possess various adaptive features which enables them to survive on land or in water.

Plants that are found in water are known as aquatic plants. They possess features which enable them to get rid of excess water as well as to stay afloat on water. For example, their leaves are waxy to enable them remain afloat.

Plants found on land are terrestrial plants and possess features that enable them survive on land. They possess features which prevent excessive water loss such as waxy cuticle.

Therefore, the evidence that paleobotanists look for that indicates the movement of plants from water to land is the possession of waxy cuticle to decrease evaporation from leaves.

In conclusion, plants show adaptations as they moved from water to land.
