Answer:
Option C, Infection causes lymphocytes to divide more rapidly.
Explanation:
Lymphocytes are white blood cells that divide at a fast rate in presence of any antigen, pathogen etc. They become active and attack the foreign antigens only when the innate immunity system is already activated. Here, the labeled nucleotide are found in larger number as compared to the number of labeled nucleotide introduced this means that the rate of division of blood cell was high and this high rate of cell division is due to the pathogen introduction.
Hence, option C is correct
Removing the oxygen in water

Answer:
Explanation:
tobacco mossaic virus is aa RNA containing virus enclosed in aaprotein coat. in above sttaed experiment when TMV cause infection in tobacco plant is leaves get infected due to replication of virus in its cells. RNA is first converted into complementary DNA and form a double stranded nucliec acid structure. it syntheaize its protein to make new coats and to wrap the newly synthesized RNA, and make a completely infected new virus which we called virion. in any case the number of coats are equal to RNA so that to prepare new viruse. n
Answer:
--> Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. Water molecules have a polar arrangement of the oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.
--> Molecules that have ends with partial negative and positive charges are known as polar molecules. It is this polar property that allows water to separate polar solute molecules and explains why water can dissolve so many substances. Water is a good solvent due to its polarity.
