87.Correct answer:B

Explanation:Three domain system is a system for classifying biological organism.Organisn are classified according to ribosomal RNA structure.It consist of three main domains-Archea, Bacteria and Eukarya

88.Correct answer:A

Explanation:Nucleoids are irregularly shaped regions inside prokaryotes that contains DNA materials along with RNA, proteind and enzymes for cellular functions.

89.Correct answer:D

Explanation: Algae and protozoa are eukaryotes here as they membrane bound nucleus in them.While bacteria is prokaryotes due to presence of nucleoids.Virus are neither eukaryotes nor prokaryotes as they do not have biological material needed for reproduction but they can replicate inside prokaryotes or eukaryotes by infecting them.
