Answer:

A

Explanation:

The reason the deletion of a nucleotide can be a lethal mutation is that it causes a frameshift mutation. This is due to teh fact that the codon sequence on the DNA is shifted by a single nucleotide. Therefore, the codons will read differently downstream from the place the deletion happened. The amino acids coded for by these codons will change too. The translated proteins will be defective and the organisms will be adversely affected, phenotypically.

melisa1 [442]

The correct answer is adaptation.  

Pollination refers to the procedure of transferring the pollen grain from the anther of a stamen to the stigma of a carpel. Some plants are amended for pollination by the wind, and some for pollination by insects.  

The plants, which are adapted for pollination via insects exhibit colorful petals and nectar to attract the insects, and sticky pollen, which adheres to the insects when they visit the flowers.
