Which statement about somatic mutations is true

They exists in all the cells of the body.

Explanation:

There are basically two different types of cells in the body one is somatic cell and other is germ cells.

The germs cells are the cells found in the eggs and sperms that is transferred to the offspring.

The somatic cells can be defined as the cells which is found in the all the cells of the body but it is not transferred from one generation to another.

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.
