The immune response due to first encounter with an antigen takes a longer time, feeble and declines rapidly. After the initial contact with an antigen, there is a period of several days during which no antibody is present, then there is a slow rise in the antibodies, followed by a gradual decline. ..

The order of reactivity of hydrogen halides is HI > HBr > HCl. ..

This test is based upon relative reactivities of various alcohols towards HCl in pressure of ZnCl 2 . In this test, the alcohol is treated with Lucas reagent, which is equimolarmixture of HCl and ZnCl 2 . Alcohols are soluble in Lucas reagent and form a clear solution. On reaction alkyl chlorides ..

The normal process of growth that occurs in every plant body is known as primary growth. It is the result of the activity of primary meristem. The process of primary growth results in the formation of primary permanent tissues such as primary xylem,..
