Which of the following is most likely to happen if a person drinks untreated water from a roadside ditch? the person might develop allergies to any mold and pollen that have fallen in the water. the person might contract an upper respiratory tract infection from viruses in the water. the person might develop an intestinal infection from pathogens in the water. the person might contract whatever strain of flu is in the community.

Option (c) is the correct answer.

Explanation:

Since it is given that the water is untreated so there will be pathogens, that is, bacteria, viruses and other micro organisms might be there in the water.

Therefore, when a person drinks water it goes into the intestine and the contamination present in water will also go into the intestine. As a result, the pathogens present in water will cause intestinal infection.

Thus, we can conclude that most likely the person might develop an intestinal infection from pathogens in the water.

genetic variation will increase because of a new habitat and food source.
