C). Germline mutations are inherited from a parent while somatic mutations are caused by mutagens in the environment.
Explanation:
MUTATION is any change that occurs to the nucleotide sequence of a gene whether caused by a mistake during DNA replication or induced by mutagens (mutation-causing substance). A mutation can be germline or somatic depending on the affected area or how it occured.
Germline mutations are mutations that affects the nucleotide sequence in a gamete or reproductive cell (germline cells). Hence, it can be inherited by an offspring during reproduction. On the other hand, somatic mutations affect body cells. It is a change in the nucleotide sequence of a gene in the body cell or somatic cell. It is usually induced by mutation-causing substances in the environment called MUTAGENS. Somatic mutations can not be transferred to offsprings and it only affects the cells of the specific area it occured.
Somatic vs Germline Mutations. ... Somatic mutations – occur in a single body cell and cannot be inherited (only tissues derived from mutated cell are affected) Germline mutations – occur in gametes and can be passed onto offspring (every cell in the entire organism will be affected)
I'm not totally sure. But in my view, <span>(4)a salt solution</span> would be used to prove that the gas produced by the yeast in the vacuum bottle could change the pH of the liquid in the flask
Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.
