I'm not sure but I think it's B
They may have a decline in
population due to a reduction in available food. They would focus more on the other prey.
Answer:
C. Nucleic acid synthesis
Explanation:
AZT, azidothymidine, is an antiviral drug used to check the viral population by blocking the process of reproduction. The azidothymidin is particularly effective against human immunodeficiency virus (HIV) as this drug inhibits the activity of reverse transcriptase which is required for the formation of a DNA copy of the RNA genome of the virus.
Similarly, Valacyclovir is an antiviral drug that inhibits viral reproduction by blocking the DNA polymerases. The Valacyclovir serves as a prodrug of acyclovir.
<h2>Exponential Population Growth</h2>
Explanation:
The model of exponential population growth predicts that the per capita population growth rate, r :
d. does not change as the population gets larger.
A population shows exponential growth if there is no limitation on growth. All members have abundant resource availability and the population displays its intrinsic rate of increase.This is also known as geometric growth .In geometric growth, rate of increase is expressed as a constant fraction or an exponent by which a particular population is multiplied.
