Choose the letter that indicates the organelle that contains most of a cell's DNA. An animal cell with definite structures labeled from A to E. The vesicles with solid particles inside are labeled A. The vesicles with no solid matter inside are labeled B.
The large membrane-bound organelle is labeled C. It is located in the center of the cell and contains a mass of densely stained granules and fibers.
The structure labeled D consists of flattened membranous-like stacks.
The tiny dots labeled E are located everywhere in the cell and do not have any membrane.

C.

Explanation:

A cell is composed of specific structures that perform specialized functions called ORGANELLES. Among these organelles, an important one exists called NUCLEUS, which is responsible for all other cellular functions as it directs them.

The NUCLEUS is located centrally in the cell and is found as a membrane-bounded organelle in cells that possess it (eukaryotes). The NUCLEUS, which is described in this question with the letter "C" contains most of a cell's genetic material called DNA.

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.
