The female mosquito is an effective vector for malaria. What makes it an effective vector?
1. it has wings
2. it lays many eggs
3. it makes noticeable noise
4. it mates several times
I wrote the answer as B, but the answer as told on my assessment book says A, (which doesnt make sense). Am i wrong or is the answer provided wrong?
I agree with the book. Vectors have to be mobile to spread disease.
thanks
Based on the information provided, your answer B is correct. The effectiveness of the female mosquito as a vector for malaria is primarily due to its ability to lay many eggs. Female mosquitoes require a blood meal to obtain the necessary nutrients for egg production. During this process, if the mosquito is infected with the malaria parasite, it can transmit the parasite to humans through its bite.
While options A, C, and D may be true characteristics of female mosquitoes, they are not directly related to their effectiveness as malaria vectors. Having wings allows mosquitoes to fly, but it does not contribute to their role as disease vectors. Making noticeable noise is a behavior associated with the wings' buzzing sound and is not directly related to their ability to transmit diseases. Mating several times also does not affect their role as malaria vectors.
Therefore, it seems that the answer provided in your assessment book is incorrect.
