Why is it necessary to give the hpv vaccine in multiple doses? the hpv vaccine contains poorly immunogenic antigenic fragments. the hpv vaccine mimics the actual infection from hpv. the hpv vaccine does not replicate in the host. the hpv vaccine must be administered to multiple portals of entry to provide protection at each portal?

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
