Antibiotics cannot kill viruses because bacteria and viruses have different mechanisms and machinery to survive and replicate the antibiotic has no “target” to attack in a virus however antiviral medications and vaccines are specific for viruses
Answer:
A. Virus
Explanation:
Viruses chose to store their data in RNA so that they can make changes as their hosts develop immunities.
Due to white moths being in a dark environment (from environment changes), the moth has evolved its wings to become darker. Thus blending in with its environment to be less visible to birds. A way of survival. Their adaption is the darker wings to its dark environment
The phenotype of the dominant gene.
The type of natural selection demonstrate is B. stabilizing selection.
There are different types of natural selections, each affecting the population density of a specific allele in a different way. In stabilizing selection, the non-extreme trait is maximized. This is seen in the curve as there is less population observed at the extreme ends of the spectrum but a greater population lying in the average, less extreme zone.
