A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.
Rainforest plants have evolved waxy coatings on their leaves that allows moisture to drip off them. their roots are shallow to help them gather nutrients from the surface of the ground or directly from other plants.
