One student designed an experiment with sugar, water, and sand. The steps of the experiment are shown below.

• Make a thumb size hole at the bottom of an 18 oz styrofoam cup.

• Roll a piece of paper into a tube and place it in the middle of the cup over the

hole.

• Fill the tube with sugar and surround the tube with sand.

• Pull out the paper tube slowly from the cup and then dip the cup into a beaker

of water.

• Watch the sugar cubes dissolve in water to form gaps in the sugar layer.

The student's experiment demonstrates the formation of

explanation:

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.
