Answer 1

Answer:

Emerging infections, as defined by Stephen Morse of Columbia University in his contribution to this chapter, are infections that are rapidly increasing in incidence or geographic range, including such previously unrecognized diseases as HIV/AIDS, severe acute respiratory syndrome (SARS), Ebola hemorrhagic fever, and Nipah virus encephalitis. Among his many contributions to efforts to recognize and address the threat of emerging infections, Lederberg co-chaired the committees that produced two landmark Institute of Medicine (IOM) reports, Emerging Infections: Microbial Threats to Health in the United States (IOM, 1992) and Microbial

Explanation:

What role do viruses play in evolution?

Viruses hijack nearly every function of a host organism's cells in order to replicate and spread, so it makes sense that they would drive the evolution of the cellular machinery to a greater extent than other evolutionary pressures such as predation or environmental conditions.

What agent causes the bubonic plague?

Yersinia pestis is the causative agent of plague, an enzootic vectorborne disease usually infecting rodents (rats) and fleas.

There are four forces of evolution: mutation, gene flow, genetic drift, and natural selection. A mutation is a random change in a gene or chromosome that can make for a physical or behavioral difference in an individual. Because it starts with a change in a gene or chromosome, it can be passed on to future generations
