Answer: <u><em> Microevolution is defined as a change in allele frequencies in a population over time. Three mechanisms can cause allele frequencies to change: natural selection, genetic drift (chance events that alter allele frequencies), and gene flow (the transfer of alleles between populations).</em></u>

Hello, to answer your question properly the problem that's effecting the population is the decrease in trees. It causes their nests and homes in the trees to be burned and make them have to migrate somewhere else then that area they were living in.

Answer:
<u>This is because the Viron has in its genome a specialized code for synthesising any missed enzyme for replication that is lacking in the host cell.</u>
<u>An example is the replication of the human DNA cells by the Immunodeficiency virus(HIV) </u>. Human cells only have enzymes for copying DNA templates, and lacks the enzyme to convert the HIV RNA genome to human DNA.However these viruses have in its genome; code for synthesising its own RNA polymerase enzymes that copies or transcribed the human DNA to HIV RNA.
<u>This ability of the viral cell to code for the host's enzyme has a therapeutic effect</u>. Drugs can be targeted at the viral polymerase enzymes to reduce the replication and therefore toxicity in the host cells.
