Blood is a complex body fluid. if a vial of blood is drawn for a blood test and is allowed to sit in a rack for some time, the red blood cells will settle out and drift to the bottom of the tube. this process indicates that at least as far as the blood cells are concerned, blood has the properties of what type of fluid?

life would be meaningless without memes

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.
