When u need a question answered you click on the camera or you could even type it but I like the camera and u just take a picture of the problem and then u go to the most recent ones that have the correct question on it and scroll down and see the answers but for me I check if there are more than 2 answers of the same one before answering it.
The teacher should clean the wound

Changes in the dna are called mutations. They can occur spontaneously. Mutations can only be passed down in gametes--sperm and egg cells. with Darwins theory at mind a mutation needs to pass the test of natural selection to remain in the gene pool. So purposly making mutation or altercations may end in diseases/illnesses or in some cases death because they body can not take it.....hope this helps if it doesnt im sorry!
