Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

Genetic defects can be cause by any chromosome, whether an autosome or a sex chromosome.
Sound would travel faster in a thick piece of metal since the molecules are closer together. However, since there are more molecules, it would be quieter on the other side than the hollow metal.
It would be A, because a fossil forms after an animal dies, and hundreds to thousands of years of soil or sediment coversit's body, preserving it. :)
The answer is C) selective breeding. This means that humans are deciding what to breed which means this is not a natural selection, but rather an artificial selection.
