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.
Chromosome mutations often occur due to an error in pairing during the crossing over stage of meiosis. The main types of chromosome mutation include translocation, duplication, deletion, and inversion. Compare point mutation. See also mutation
we learned about this in living environment! for example: humans used to have tails but the humans without tails offspringed with the ones with tails causing the genetics to take over making different traits appear in offspring. Therefor, the answer is D.
An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.
