I NEED A VERY DETAILED EXPERT HELP ON THIS. IT HAS TO BE HALF PAGE LONG AND IT CAN HAVE OTHER SOURCES CITED IN IT AS WELL. PLEASE READ CAREFULLY BEFORE ANSWERING. I WILL LEAVE A VERY GOOD FEEDBACK IF YOU ARE RIGHT. THANK YOU!

In various parts of our class we have dealt with the evolution of virulence.

A. If a pathogen is directly transmitted from person to person, what would be the expectation in terms of evolution of virulence? Explain why that might be. You can give an example, but just the example is not sufficient.

B. Malaria and other vector borne diseases complicate the picture, and a case could be made for moderate virulence as the optimal evolutionary outcome for Plasmodium. Explain why this might be (hint: consider the symptoms and general condition of moderately ill malaria patients, and what this means for transmission ofPlasmodium)

People aren’t the only agriculturalists. Leaf-cutter ants, for example, cultivate a fungus from the leaves they collect. The fungus requires the plant leaves the ants collect to grow, as a nutritional substrate, which the ants actively harvest to help maintain the fungal community.

A. Is this an example of a predator-prey, host-parasite, mutualistic, or sexual conflict co-evolution?

B. If it is an antagonistic relationship, how are the two species in conflict? If it is a mutualistic relationship, how do both species benefit?

C. Describe how the above example is representative of co-evolution

D. Imagine the ants find a new food source that is higher in quality and easier to acquire than the fungus. Hypothesize what you think might then happen to the antagonistic or mutualistic relationship described in part b.)
