Which best describes somatic mutations?
a they are usually passed on to offspring.
b they can cause different kinds of cancer.
c they always result from point mutations.
d they only occur in reproductive cells.

B) they can cause different types of cancer

Explanation:

They can cause different kinds of cancer.

Explanation:

Mutations may be defined as the sudden, heritable change in the DNA sequence of the organisms. Mutation are mainly of two types : Somatic mutation and germ line mutation.

Somatic mutation occurs in the somatic cells of the body and are not inherited to the next generation. The somatic mutation can causes the conversion of proto oncogenes into the oncogenes. These mutation generally like to develop cancers in the somatic cells of the body.

Thus, the correct answer is option (B).

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
