Materials, such as sand and rocks, are constantly being added to land masses through the process of deposition. deposition occurs when the weights of the materials are greater than the forces that are transporting the materials.

jeremiah sets up an experiment to better understand the process of deposition. in his experiment, he places a pile of sand at the top of a tube. then, he pours water down the tube at varying speeds. finally, he measures the amount of sand that is deposited throughout the tube.

what is the test variable (independent variable) in jeremiah's experiment?

a.
the initial quantity of sand
b.
the speed of the water
c.
the type of tube that was used
d.
the quantity of sand in the tube

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.
