Base your answer on the information and diagram below and on your knowledge of biology To study how bacteria respond to antibiotics, four paper discs, three treated with different antibiotics and one treated with water, were placed on a nutrient
source with bacteria and left for 24 hours. The water and the antibiotics on the discs diffused into the nutrient source. If the antibiotic stopped the bacteria
from growing, a circular area of no bacterial growth around the discs could be seen

In this experiment, the purpose of using a disc treated with water is that it
O serves as the conclusion for the experiment
is needed to provide additional moisture
O serves as a control for the experiment
O is needed as a standard safety procedure

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.
