Benedict’s solution tests for the presence of glucose, and iodine solution tests for the presence of starch. In the presence of those molecules, the indicator mixture will change colors. A student is performing a carbohydrate lab in class and is using their data chart of knowns to determine the identity of unknown substances. After placing 2 mL of the unknown carbohydrate solution in the test tube, the student drops in 5 drops of Benedict’s solution and places it in a hot water bath for 3 minutes. They observe that there is no color change. What claim can the student make about the carbohydrate in the test tube? A. The carbohydrate must be a disaccharide because there was no color change for the Benedict’s test

B. The carbohydrate must be a polysaccharide because there was no color change for the Benedict’s test.

C. The carbohydrate must be a monosaccharide because there was no color change for the Benedict’s test.

D. The carbohydrate must be a disaccharide or polysaccharide, but the student has not collected enough data to correctly determine which yet

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.

explanation:

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community
