Mutations are the material upon which natural selection acts. Evolution is a two sided coin. One side is mutation; the other side is natural selection.
Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.

How does chance play a role in evolution?
Evolution is caused by adaptations (favorable traits) that sometimes come from mutations. Mutations happen by chance, and this is how chance plays a role in evolution.
Evaluate the significance of mutations and repair of mutations to the evolution of sexual reproduction?
evaluate the significance of mutations and repairof mutations to the evolution of sexual reproduction
Are all mutations bad Explain your answer?
No
Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Why are mutations are important for evolution?
Mutations serve up the variations in organisms to natural selection. The reproductively successful variations pass on these successful traits to progeny and allele frequencies change because of this and this is evolution.

How does the modern theory of evolution explain the loss of vestigial organs?
Use it or lose it. (If it's no longer functional, then any gene mutations that occur will not be weeded out.)
Why do mutations that occur in the skin or nervous system tend to have little effect on the evolution of a species?
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.

Are all mutation harmful?
Mutations that succeed [are beneficial] provide Evolution, so not at all.
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
How do you explain in brief the evolution of computer?
