A mutation is considered beneficial if it confers a selective advantage that improves the organism's chances of survival and reproduction in its environment. Harmful mutations typically decrease an organism's fitness and can be detrimental to its survival. The impact of a mutation on an organism's survival depends on the specific environment and circumstances in which it finds itself.
A helpful mutation is called a beneficial mutation. These mutations can result in an improved or advantageous trait that increases an organism's chances of survival and reproduction.
Mutation leads to variation which in some cases is helpful to insects, birds, etc (except humans) to blend in with their environments so there is better survival
a beneficial mutation in an animal, plant, cell or bacteria will allow it to have a better chance of survival and allow it to continue passing on its DNA in its offspring. a harmful mutation does the exact opposite it hinders the animals survival and will eventually lead it's species to extinction.
Mutations are both! Mutations lead to genetic variation. (so does fertilization) It gives the organism greater chance of survival if the environment changes. Mutations could lead to different height or eye color etc. They could also lead to disadvantages as well. If the adaptation in an environment is tall and a mutation is made for short then the mutation isn't very advantagoes. If the environments adaptation is for an immunity to a chemical like pesticides vs bugs and a bug has an immunity due to mutation then it is beneficial

Mutation is caused when chunks of chromosomes cut taken or fall off. So the chromosome with the DNA causes a mutation which sometimes is helpful but mosty hard to live with.
They help disperse seeds to locations where they won't compete with the parent tree, thus upping their chances of survival, mostly by eating the fruits or when seeds cling onto them.
New mutation in mice causes the coast to be normal in today's world. This is a well ask question.
