Answer:
e. infection causes lymphocytes to divide more rapidly
Explanation:
The cell cycle includes interphase and M phase which in turn together produce daughter cells from the existing parent cells. DNA replication occurs during the S phase of interphase to ensure that the daughter cells obtain the identical DNA present in the parent cell.
Lymphocytes are one of the types of white blood cells and are involved in cell-mediated and antibody-mediated immune responses. These cells are present in the blood as well as in lymphatic tissues. During the given experiment, lymphocytes exhibited a higher rate of incorporation of labeled nucleotide after the introduction of a pathogen in the culture. This suggests that the introduction of pathogen triggered the cell division in lymphocytes to produce more lymphocytes to fight the infection.
Answer: Some of the intestinal symptoms elicited by pathogens such as salmonella, shigella, and Escherichia are due to the presence of lipopolysaccharides.
Pathogen associated molecular patterns binds to toll like receptors to elicit a response include lipopolysaccharide or LPS. The bacterial component interaction with the host involves LPS and other components of cell wall causing a septic shock. The triggering of any event of septic shock is directly related to the release of LPS or other bacterial toxins into circulation. Pathogen associated molecular patterns are the molecules which are made by the pathogen and needed for their survival or pathogenic character includes LPS.
Answer:
<u><em>Complementary base pairing is important in DNA as it allows the base pairs to be arranged in the most energetically favourable way</em></u>
<u><em>It is essential in forming the helical structure of DNA. It is also important in replication as it allows semiconservative replication</em></u>
<u><em>A complementary base is either of the two nitrogen-containing sections of a nucleotide that bond together to connect strands of DNA or RNA</em></u>
<u><em>DNA and RNA are complex molecules that are central to genetics and both are made of things called nucleotides.</em></u>

Answer:
One - third.
Explanation:
The children and adults must be protected from the malnutrition and each individual has the right to attain the minimum nutrient requirement. Different programs run in U.S.A. to fulfill the nutrient deficiency.
RDA (Recommended Dietary Allowance) is a type of allowance given to the individual for the average daily intake to meet the nutrient requirement. Adequate Intake (AI) is provided when the individual do not have proper proves to develop RDA. The home delivered meals provide atleast one-third of the RDA.
Thus, the answer is one-third.
