Answer:

Genetic drift

Explanation:

Genetic drift is defined as the random change in allelic frequencies from one generation to the other.

Genetic drift is an evolutionary mechanism in which the allelic frequencies in a population change through many generations. Its effects are harder in a small-sized population, meaning that this effect is inversely proportional to the population size. Genetic drift results in some alleles loss, even those that are beneficial for the population, and the fixation of some other alleles by an increase in their frequencies. The final consequence is to <u>randomly</u> fixate one of the alleles. Low-frequency alleles are the most likely to be lost. Genetic drift results in a loss of genetic variability within a population.  

Genetic drift has important effects on a population when this last one reduces its size dramatically because of a disaster -bottleneck effect- or because of a population split -founder effect-.

NEED HELP PRETTY PLEASE WITH A CHERRY ON TOP
Kruka [31]

ANSWERS:

They are both ionic compounds.

These compounds are made up of H^{+} cations (positively-charged ion) and either NO_{3}^- or SO_{4}^{-} anions (negatively-charged ions).

Their names both end in -ic acid.

Acids are named based on their anion. With acids like these where the anion is attached to a hydrogen cation, we name such acids with the the suffix “-ic”.

They both contain polyatomic ionic.

NO_{3}^- and SO_{4}^{-} are both polyatomic ions.

"Poly-" = many

"ions" = have a + or - charge

So, yes, these are ions that are made up of several atoms (not just one atom like H^{+})
