Answer:
The four nitrogenous bases that are present in DNA are adenine, guanine, thymine and cytosine. These nucleotides can be radiolabelled before the new DNA forms and the composition of specific nucleotide of DNA can be estimated.
During the experiment, research team found that the incorporation of radioactive nucleotides composition increase after the introduction of pathogen in the culture. This means that the cell starts producing more number of cell to fight against the pathogen. The infection of pathogen is mainly responsible for the division of lymphocytes more rapidly.

The answer is b photosynthesis
The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton describes the availability of carbon in the ocean and its use by marine processes
The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton.
<u>Explanation:</u>
The carbon is found in the ocean is utilized by the phytoplankton found in the ocean. The carbon sinks in the ocean and then the process of photosynthesis required the carbon dioxide and the sunlight.
The ocean plays an important role in the carbon cycle, the carbon spreads in the ocean are called the ocean sink because it takes up more carbon from the atmosphere. The chemical and biological processes influence the carbon by producing more carbon dioxide in the atmosphere.
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration
