Assuming you have been posted to a community where malaria is very endemic. There is a high rate of absenteeism among your students due to incidents of malaria. As part of your community engagement explain how you would educate on malaria prevention taking the following into consideration:a) Name of the vector and the species of the parasite that cause the diseases in Africa; b) Two chemical and two biological ways of reducing the population of mosquitoes; c) Two in-house measures to prevent mosquitoes bite;d) The stages in the life cycle of the mosquito;e) The names of three African countries that participated in the trial of malarial vaccine.
Below are statements about symbiosis.  Choose the correct responses. ( Only pick one answer per [ ] )       ["Commensalism", "Mutualism", "Parasitism"]  is a term that describes when two organisms both benefit from a relationship.  One example of this you will view is lab is       ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"]  .       ["Commensalism", "Mutualism", "Parasitism"]  is a term that describes when one organism benefits, while the second organism is not harmed, and does not benefit.       ["Commensalism", "Mutualism", "Parasitism"]  is a term that describes when one organism benefits while the second organism is harmed.  In lab you will explore       ["Viruses Infecting Bacteria", "Yeast Fermenting sugar", "Bacteria such as Rhizobium living in plant structures called root nodules"]  as an example of this relationship.
Compare parasitism and mutualism for the two factors (A and B) below.   A)  What distinguishes these two strategies from the other strategies for interaction?      B)  What is the long-term benefit to the micro-symbiont as far as access to a new host? C)  What is the cost (e.g. DNA that needs to be maintained)?
