Describe the path of a nitrogen atom through four parts of the nitrogen cycle. Be sure to explain the processes involved in the transfers. Note when a form of nitrogen is available to plants.

One of the ways the path of a nitrogen atom begins is as a part of an ammonium ion. A plant takes up the ion and uses it to make an organic molecule through assimilation. The organic molecule falls back to the ground as part of a leaf. The leaf is decomposed by bacteria, and it is converted back to ammonium by ammonification. The ammonium ion is then converted to nitrite by nitrifying bacteria through nitrification.

Explanation: That's what popped up after I hit submit so that's the answer hope this hepls.

Cells contain a transforming factor summarizes the findings of Griffith.

Explanation:

Numerous experts assigned to the description of DNA as the genetic material. During the 1920s, Frederick Griffith obtained an outstanding invention. He was inquiring two separate forces of a bacterium, called R (rough) strain and S (smooth) strain. He infused the two strains into mice.

Griffith settled that the R-strain bacteria must have brought up a "transforming principle" from the heat-killed S bacteria, which enabled them to "transform" into smooth-coated bacteria and become injurious. He called this method transformation, as something was "transforming" the bacteria of one strain into another strain.
