The type of natural selection that is described here is called a simple positive selection.We know this because p<span>ositive selection is the process by which new advantageous genetic variants sweep a population or remain resistant.</span><span> This type of selection is known when insects have greater endogenous resistance, with the insecticide being the selective agent.</span>
Answer:
adding nucleotides one by one
Explanation:
A typical primer is about five to ten nucleotides long. The primer primes DNA synthesis, i.e., gets it started. Once the RNA primer is in place, DNA polymerase "extends" it, adding nucleotides one by one to make a new DNA strand that's complementary to the template strand.
<span>This finding that all known organisms use genetic information to produce protein molecules via the same genetic code strongly supports the hypothesis that all organisms are descended from a single common ancestor.
Genetic information is the biological information coded in the dna or rna sequences, like chromosomes.
A specie from which two different species are evolved is a common ancestor.</span>
The answer is; C
This phenomenon is called bottleneck effect and drastically affects small populations in comparison to large ones. The mudslide wipes off most of the population B at the base of the hill base. Due to their small population, a large proportion of the population is lost and the pollution loses most of its alleles leaving a small proportion to continue the population succession. Its diversity is hence reduced as it repopulates. The larger population is not greatly affected because it covers much of the hillside.
The enzyme protease helps in the digestion of the proteins and peptides. This enzyme breaks the protein into smaller fragments, and then into amino acids. These amino acids can be easily absorbed by the body. The protease is produced is inactive state in the pancreas. It is activated with the help of another enzyme. This activating enzyme only works when the food had entered the stomach.
Hence, the answer is 'protein'.
