He got to that conclusion like this: Regarding qualitative tests, he saw that no protein was present but that DNA was present. The chemical analysis showed that phosphorus was present in DNA not in protein. Talking about enzyme tests he saw that transformation did not happen when they added enzymes to the DNA.
Explanation:
Qualitative chemical and catalyst tests helped Avery determine DNA because the remodeling principle by conducting a series of tests to search out if the remodeling principle was DNA or a macromolecule and therefore the result's that no macromolecule was present however that DNA was present.
Although varied scientists engaged in diplococcus analysis throughout the primary 1/2 the 20th century, 2 of those researchers vie a particularly vital role within the course of events that junction rectifier to the invention of deoxyribonucleic acid because of the hereditary material. One in all these people was Oswald Avery.
Answer:
Inhibitory influences from neuroglia, and the absence of growth-stimulating cues.
Explanation:
Neurogenesis in adults is limited by Inhibitory influences from neuroglia, mainly from oligodendrocytes, and the absence of growth-stimulating cues that are present during fetal development. It is so hard to repair a damaged nerve because nerve cell like other cells can't divide and increase in number, they can't renew themselves. Due to no division, the nerve cells does not increase in number and therefore can't repair themselves.

Fever is the process of the body to eliminate the foreign particle such as Ag from the body body of an individual. Using pain reliever which is double of a fever reducer is not the best practice as it will impaired the first line of immunity which is fever.
Fever is the increase in the range of the temperature of the body at which it stops the replication or ability of reproducing of Ag in the body of the infected individual.
Thus, the correct answer is - option A.
