Final answer:
Killing Anopheles mosquitoes prevents the transmission and reproduction of Plasmodium falciparum. Untreated African sleeping sickness invariably leads to death due to severe neurological symptoms and nervous system failure.
Step-by-step explanation:
Killing Anopheles mosquitoes affects the Plasmodium protists by disrupting their life cycle. Anopheles mosquitoes are vectors for Plasmodium, specifically Anopheles gambiae, which transmits Plasmodium falciparum. This species of Plasmodium is responsible for the majority of malaria cases and related fatalities worldwide. By targeting these mosquitoes, the transmission of Plasmodium to humans is prevented, which in turn stops the reproduction of the parasite since it cannot complete its life cycle.African sleeping sickness, if left untreated, invariably leads to death because the causative parasites, Trypanosoma species, affect the nervous system. The progression of the disease results in severe neurological symptoms and eventually, neurological failure, rather than respiratory, liver, or cardiovascular collapse as suggested by some of the incorrect options.
Killing Anopheles mosquitoes affects the Plasmodium protists by preventing their transmission. Plasmodium species, such as P. falciparum, are responsible for causing malaria in humans. These protists require both a mosquito and a vertebrate host to complete their life cycle. Killing mosquitoes helps to disrupt this cycle and reduce the spread of malaria.In contrast, African sleeping sickness, caused by the trypanosome parasite, invariably leads to death without treatment due to its impact on the nervous system. The disease affects brain function, leading to a range of symptoms including neurological disorders and sleep disturbances.
