question 8 (bonus) (1 point)
which organism causes a disease that is untreatable?
trypanosoma gambiense
plasmodium vivax
necator americanus
trichanella spiralis

Explanation:

To determine which organism causes an untreatable disease, we analyze each option:

• Trypanosoma gambiense causes African trypanosomiasis (sleeping sickness). The disease can be difficult to treat, especially in later stages, and some forms are challenging due to drug resistance and the parasite's ability to evade the immune system.
• Plasmodium vivax causes malaria, which is treatable with antimalarial drugs.
• Necator Americanus is a hookworm, and its infections are treatable with anthelmintic medications.
• Trichanella spiralis causes trichinosis, which is treatable with medications like albendazole or mebendazole.

Among these, Trypanosoma gambiense - related disease is often considered to have significant challenges in treatment, with some cases being hard to fully treat (though "untreatable" can be a relative term, it is the most fitting here compared to the others which have established treatments).

Answer:

Trypanosoma gambiense
