Can mutations add information in organisms?
mutations in dna can be advantageous and lead to charecteristics that help a person survive or increase it chances of survival.
Why is it easy for a virus to mutate?
Mutations are very common in all organisms. There are various mechanisms of repair in most cellular organisms that detect and correct these mutations both as they occur and afterwards. Viruses are very simple organisms and contain very few proteins. Repair mechanisms are limited to the simplest mechanisms of the host cell. Since much fewer of the mutations are repaired, it is easy for a mutation to become permanently incorporated into a virus genome. Viruses also frequently use single stranded DNA or RNA, in which case mutations are much harder to detect, even for the simple repair mechanisms that may take place during the host cell's replication processes.
Why aren't somatic mutations passed on to the next generation?
most genes mutations are recessive, and since most organisms have two of every genes, the normal genes will dominate the recessive genes.
When changes occur in the genes of six cells theses changes will lead to what?
It will lead to mutations in the parent organisms =)
What are some ways that mutations in some living things are helpful to those organisms but harmful to humans?

Are chromosomal mutations more common in plants or animal?
chromosomal mutations can happen in any organism, but they are specially common in plants. Edited answer: Chromosomal mutations are more common in plants because plants remain seated at one place receiving all short of radiations and temperature range.
The mutations that breeders induce in organisms are passed on to the organisms?
offspring
Are mutations more common in sperm cells or egg cells?
It depends on the age of the person. There are more mutations and defects in eggs as the woman ages. However, as men are constantly producing more sperm cells they will inevitably produce more cells that have mutations. The percentage of sperms cells that have mutations will increase as the man ages.
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.
Animals are affected by radiation true or false why?
Yes they are. Simpler life forms have more resistance. Radiation catalyses mutations in the DNA sequences of organisms. This is why you can get cancer from radiation (e.g. skin cancer from ultra-violet radiation) because cancer is caused by mutations in multicellular organisms.
Although genetic mutations may occur spontaneously in organisms the incidence of such mutations may be increased by?
Radioactive substances in the environment
How does natural selection help evolution?
Mutations are random... they can be good, bad, or neutral.Natural selection makes evolution a non-random process by making it more likely that organisms with bad mutations will die without mating, while those with good mutations will live on to pass the gene to the next generation making it more fit.

A sudden permanent change in a organisms dna called?
Gene
Why did complex organisms that inhabit the earth develop?
"They" happened by accident (i.e. mutations), and the ones that were more efficient eat the less efficient. That's life.
What is the define of mutagen?
An external agent that increases the rate of mutations of cells or organisms.
Do all organisms follow the rules of genetics?
Yes they do. There are, of course, occasional mutations.
