nydimaria [60]

Answer:

D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem ​

Explanation:

In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.

In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.

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.
