Arianne 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 Arianne? 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
Parasitic bacteria like <em><u>Clostridium botulinum</u></em><em><u> </u></em>or salmonella cause food poisoning. The symptoms of food poisoning appear within a few hours of food ingestion or may be after 6 to 10 days. All the symptoms listed here like nausea, fever, and diarrhea occur due to food poisoning. It is clear that she is suffering from food poisoning and since these bacteria caused problems to Arianne without benefiting her in anyway, they are considered as parasites.
Also, mutualistic bacteria are the ones which live in the body of host and provide certain benefits to the host, a commensalistic organism is the one which gets benefits from the host without harming the host, a predatorial organism on the other hand kills the another organism in order to get benefits but in the question nothing like that is happening to Arianne so all these options are incorrect.
Human heart produces unique sound when blood flows from one chamber to the next chamber. The two main sounds produced by heart are lub abd dub sound.
The doctor's examine the Janetta's heart and told that she has incompetent right atrioventricular valve. The doctor must have heard the swishing sound after the closing of right atrioventricular valve. This sound is the direct indication of incompetent AV valve.
