Answer:

The ionizing radiation affects the DNA of the wild animals (wildlife), similarly as it has influence on the DNA of humans.

Explanation:

The Chernobyl disaster was a nuclear accident that occurred on Saturday 26 April 1986, at the No. 4 nuclear reactor in the Chernobyl Nuclear Power Plant, near the city of Pripyat in the north of the Ukrainian SSR. (Reference: Burgherr, Peter; Hirschberg, Stefan (2008). "A Comparative Analysis of Accident Risks in Fossil, Hydro, and Nuclear Energy Chains". Human and Ecological Risk Assessment: An International Journal. 14 (5): 947–973. Direct Reference From officials: chernobyl (International Atomic Energy Agency  Vienna International Centre, PO Box 100  A-1400 Vienna, Austria))

horrorfan [7]

The most likely explanation to the statement that digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach is C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

The pH of the mouth is near neutral whereas the pH of the stomach is acidic due to the hydrochloric acid present in the stomach.

All enzymes, including the digestive enzymes, require a certain pH at which they are better able to function. If the pH is altered, then the shape of the enzyme changes, which affects the shape of the active site of the enzyme. As a result, the substrate is no longer able to fit in the active site.

Hence, those digestive enzymes that function in the mouth will not function in the stomach due to the altered pH.

Although a part of your question is missing, you might be referring to this question:

Digestive enzymes released in your mouth break down carbohydrates there but stop working in your stomach. which is the most likely explanation?

A. Enzymes have only one active site. Once a substrate binds, that enzyme is no longer usable.

B. Enzymes are changed in a reaction. Enzymes made in the mouth are used up by the time they get to the stomach.

C. The pH of your mouth and stomach are very different. The shape of the enzyme is affected by pH.

D. There are no substrate molecules left when the enzyme reaches the stomach, so the enzyme stops working.

skad [1K]
The environment is studied at different levels & stages.
Biosphere: The biosphere is the zone in which life exists. It consists of the atmosphere& the hydrosphere alongwith the earth surface where living beings live. 

The biome is a community of plants and animals (flaura & fauna).
Community: A community is a group of people/living beings who live in a specific location. It is used to describe two or more populations of different species that exist at same place.
Population: A population is the multiple individuals or living organisms of a single species that live in an area. 
The populations are formed by lalrge number of groups of organisms.
Group of populations form communities. The group of all communities form a biome, which exist in the biosphere.
