Check all of the following that are possible consequences of reassortment in viruses. a. reassortment can be used by researchers in the lab to produce "live attenuated" vaccines. b. reassortment can lead to the evolution of new strains of influenza. c. reassortment can recombine genetic elements from different influenza strains.

All options are correct.

Explanation:

Viruses can be considered in the border line between the living and non living organisms. The viruses behaves like non living outside the host and once enter in the host starts reproducing and acts as living organisms.

Reassortments is the formation of the new genetic material in the host. This reassortment ability can be used by the scientists for the vaccine preparation. This reassortment are responsible for the evolution of new strains as well as can form new genetic material from the different strains of virus.

Thus, all given options are correct.

The base of any age group graph represents a population below the age of fifteen. ... Thus, rapid growing graph has a wider base while a slow growing population has a narrower base. a steady population graph has base approximately equal to the population age group above it.
