What approximate percentage of lymphocytes is seen at age 4?

Blood is composed of several types of cells:

There are five types of white blood cells & approx %age they made up in blood are:

•Neutrophils (55% to 70%)

•Band neutrophils (0% to 3%)

•Lymphocytes (20% to 40%)

•Monocytes (2% to 8%)

•Eosinophils (1% to 4%)

•Basophils (0.5% to 1%)

When children are more than 4 year old they  have higher  % age of lymphocytes than the adults do.

explanation:

yes you are doing it right great gob

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
