The research team used their experiments to study the incorporation of labeled nucleotides into a culture of lymphocytes and found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. they concluded that

Infection causes lymphocytes to divide more rapidly

Explanation:

The research team used their experiments to study the incorporation of labeled nucleotides into a culture of lymphocytes and found that the lymphocytes incorporated the labeled nucleotide at a significantly higher level after a pathogen was introduced into the culture. They concluded that Infection causes lymphocytes to divide more rapidly. The pathogen causes infection and thus the it was found that the lymphocytes incorporated the labeled nucleotide at a significantly higher.

. He concluded that infection contributes to a more rapid division of lymphocytes

Explanation:

The team of researchers used their studies to investigate the integration of marked nucleotides into lymphocyte culture and noticed that lymphocytes integrated the labeled nucleotide at a higher level after introduction of a pathogen into the culture. He concluded that infection contributes to a more rapid division of lymphocytes.

a- all cells come from pre-existing cells

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
