How does the domain eukarya differ from the other two domains? a) all organisms in the domain are heterotrophic. b) all organisms in the domain are multicellular. eliminate c) all organisms in the domain have eukaryotic cells. d) all organisms in the domain have prokaryotic cells.

The correct answer would be C)All organisms in the domain have eukaryotic cells.

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.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
