Mutations are important for evolution because
a. are the source of new genetic variation
b. improve the survival of organisms
c. allow individual organisms to evolve
d. remove excessive genetic variation

A. are the source of new genetic variation. And this makes sense because mutation result in new alleles and sometimes even genes. These alleles make evolution occur because it changes the structure of the gene and the phenotype. This occurred in parts of Africa and Europe in which mutations in the genes caused children of lactose intolerant parents to be lactose tolerant. 

Hope this helps :)

Swating at a bee and it stings

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.
