Dominant' traits will actually disappear faster if they are disadvantageous.
Think about it: if everyone who has even a single copy of a particular allele is at a disadvantage (manifests the phenotype, in this case six fingers), then even single copies are selected against.
In the case of recessive traits, selection occurs only against homozygous carriers, who may be very rare if the allele itself is rare.
A concrete example would be something like Tay-Sachs disease. If the allele that causes this were dominant, every carrier would die before adulthood, and it would occur only as a very rare de novo mutation. But because it is recessive, it persists for now; heterozygous carriers have no disadvantage.
Question: Many molecules are moved through the body by?
Answer:<u> The molecules are moved through the body by uses special transport proteins to move molecules across the membrane that cannot pass thorough on their own. Usually large molecules. Carrier proteins blind and carry the molecules across the cell membrane. They provide an open channel of passageway through the cell membrane for molecules to move across.</u>

Answer:
A. Stores DNA
Explanation:
The nucleus of the cell holds the genetic information of a cell, which is known as DNA. The nucleus is also known as the control center of the cell because it dictates the type of proteins that will be made. These proteins are used for the cellular processes that determines its function.
