Most organisms can be divided into two categories - prokaryotes and eukaryotes. what is the main difference between these two categories?
a. prokaryotes do not possess any means of locomotion and are thus unable to move.
b. eukaryotes are found in all of the six major taxonomic kingdoms.
c. eukaryotes are living organisms whereas prokaryotes include some nonliving matter.
d. prokaryotes do not possess a nucleus or any other membrane-bound organelles.

organisms that are both used in toothpaste as well as cause malaria are protista and monera.

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.
