Which statements about mutations are true? check all that apply

A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence differs from what is found in most people. Mutations range in size; they can affect anywhere from a single DNA building block (base pair) to a large segment of a chromosome that includes multiple genes.

Explanation:

mutations are rare

most forms of cancer are caused by somatic mutations

Explanation:

i think its 2, 4,5

Explanation:

Answer;Mutations are rare.Most forms of cancer are caused by somatic mutations.Explanation;Mutations are sudden spontaneous and random changes that occurs in the genetic make up of an organism. They are alterations that occur in the nucleotide sequences in the genetic make up or the genome of organisms.Mutations are rare but when they occur they may be advantageous or disadvantageous to an organism. Advantageous mutations have allowed organisms to adapt to their environment, and also resistance to diseases such as malaria in sickle cell.However mutations may have disadvantageous and deadly effects, for example most of cancer are caused by somatic mutations or mutations in the body cells.

Mutations are rare, Most forms of cancer are caused by somatic mutations, and (I think) Germline mutations occur in body cells. 

Mutations in your genes are happening almost every time your cells divide, they're just so minor that they basically dont matter, but every once in a while a serious one will occur, which, can cause permanent damage or death.

The statement that is false is the a), that mutations must be present in parents and then passed to offspring. mutations results from random errors in the replication of the dna and some mutations can be inherited but others no. so mutations are not necessarily present in parents.all the others are true.
