Question

ariane recently traveled abroad where she enjoyed eating food from different countries and learning about different cultures. a week after she returned home, she checked into the hospital with signs of nausea, fever, and diarrhea. what best explains what happened to ariane? a parasitic bacteria contaminated her food. a mutualistic bacteria infected her digestive system. a commensalistic organism is now living in her intestine. a predatorial organism is consuming her natural bacteria.

Explanation:

Ariane got sick after eating contaminated food abroad. Parasitic bacteria in contaminated food can cause symptoms like nausea, fever, and diarrhea. Mutualistic bacteria would not cause illness, commensalistic organisms don't typically cause such symptoms, and a predatorial organism consuming natural bacteria isn't related to food - borne illness from contaminated food. So the best explanation is a parasitic bacteria contaminated her food.

Answer:

A. A parasitic bacteria contaminated her food.
