Please discuss the 3 types of symbiosis and provide examples of each.

Dengue hemorrhagic fever (DHF) is endemic in many tropical areas of the world. Suppose an unseasonably warm spring has led to increased population of mosquitoes and subsequently epidemic levels of DHF infection in Sri Lanka during this year. Under normal circumstances, community X in Sri Lanka has an average of 12 DHF cases per month. Define endemic?  Define epidemic?

Add Numbers 1-9 in order of when the statement is found in the entire malaria life cycle.  #1 is already placed.              Mosquito bites infected human and becomes infected.              The host experiences symptoms of fever and chills.              Parasite travels to the liver.              Parasite travels through the blood stream and attaches to the red blood cell.  1          Infected mosquito transfers parasite to human.              Red blood cells bursts and infects other red blood cells.        There is a depletion of oxygen to the body.              Parasite reproduces in the liver cells.            Parasite reproduces in the red blood cell.

Background: An area has two different Anopheles species, species A and species B.  Both can vector Plasmodium, although Plasmodium develops best and is transmitted best by species B. Species A is dominant because its larvae outcompete species B in the main shared breeding sites, small lakes, and ponds. Therefore the population of B is currently small. The small lakes and ponds are also the source for the main food source in the region, fish, grown in fish farms. There is grazing land, but other than chickens, the local population does not have livestock. Species A is largely endophilic, species B is exophilic. In other localities, species A and B will also feed on cattle, and B appears to prefer cattle. Both species like to roost during the hot day in rock overhangs and small caves. Develop an alternative targeted strategy that might work well in this situation. Use only strategies that have been used successfully in the field and avoid "just spray everything" strategies.

List five reasons for an increase in numbers of emerging infectious diseases

How can we improve the prevention and control of parasites? please dont give a yes or no response

Some living things exist in a very close relationship which benefits one organism but does not hurt the other organism. This type of relationship is called
