Answer:

Reproductive isolation refers to the inability of an organism or species to breed successfully with other organism or species.

It may arise from various factors such as:

  • Geographical isolation such as river, mountain, etc
  • Behavioral changes such as mating time or season, mating rituals, mating location etc.
  • Physiological differences such as change in shape of sex organs which causes lack of fit between copulatory organs.
  • Genetic differences.

Reproductive and geographical isolations between two populations (of same species) inhibit the flow of genes among them. Slowly, these isolations increase the variations in the gene pools of the two populations.

These genetic variations keep on increasing with time. In addition, as an adaptation to their surrounding or habitat the two populations would develop different behavioral and physiological changes

With time, these differences will increase up to such an extent that the two populations would not be able breed with each other. Hence, it would lead to the evolution of one or both the populations into new species.

PLATO:

Reproductive isolation refers to populations of organisms that have become isolated from each other. A geographical barrier or a genetic change can cause this isolation. As a result, the organisms are not able to successfully reproduce with each other. The two populations evolve separately from each other, likely developing different frequencies of genetic mutations and possibly selecting different traits.

yanalaym [24]
B and C are correct - A is incorrect as natural selection affects any generation of species. D is also incorrect as any species population change in an ecosystem inevitably affects another, even if it isn't a predator-prey relationship.

kolbaska11 [484]

The frequency <em>p</em> of the yellow (A) allele is  <em>p</em>= 0.3

The frequency <em>q</em> of the blue (a) allele is  <em>q= </em><em>0.7</em>

Hardy–Weinberg equilibrium,  states that allele and genotype frequencies in a population will remain constant from generation to generation. Equilibrium is reached in the absence of selection, mutation, genetic drift and other forces and allele frequencies p and q are constant between generations. In the simplest case of a single locus with two alleles denoted A and a with frequencies f(A) = p and f(a) = q, the expected genotype frequencies under random mating are f(AA) = p² for the AA homozygotes, f(aa) = q² for the aa homozygotes, and f(Aa) = 2pq for the heterozygotes.  

p²+2*p*q+q²= 1       p+q= 1     q= 1-p

yellow (p²)= 9%= 0.09               p= √0.09= 0.3

green (2*p*q)= 42%= 0.42        

blue (q²)=49%= 0.49                q=1-0.3= 0.7 <em>or</em> q= √0.49= 0.7

What enzyme catalyzes the attachment of an amino acid to trna?
3241004551 [841]
The answer is an aminoacyl-tRNA synthetase.

<span> The aminoacyl-tRNA synthetase is an enzyme responsible for the attachment of an amino acid to tRNA. First, it binds the ATP and the amino acid which results in aminoacyl-AMP and inorganic pyrophosphate. Aminoacyl-AMP binds the appropriate tRNA molecule. The aminoacyl group dissociates from the complex with AMP and binds the tRNA molecule creating aminoacyl-tRNA.</span>
