This is option 2 hope I helped. :)
The biochemical analysis of different chlorophyll pigments in plants would be most useful in determining <span>D. which plants might have a common ancestor.
The field of biology that deals with the similarities between these plants is called comparative biochemistry. If these plants have similar DNAs, then they are more closely linked in evolutionary terms, and thus it is quite possible they have the same predecessor.

Answer:
This question lacks options, options are: a. beta-D-fructofuranose b. amylose c. uronic acid d. N- acetylglucosamine. The correct answers are c and d.
Explanation:
Glycosaminoglycans are very long, unbranched polysaccharides, made up of repeating units of disaccharides. One of the disaccharides is always an amino sugar, which can be N- acetylglucosamine. The other is uronic acid (it can be iduronic acid or glucuronic acid and is often sulfated at position 2). The amino sugar is usually sulfated and the rest of the sugars have carboxyl groups, which give the structure a negative charge, which attracts a large amount of cations such as sodium. Glycosaminoglycans are often covalently bound to proteins to form proteoglycans. Hyaluronic acid is the only glycosaminoglycan that does not form protein bonds and does not have sulfate groups in its structure.
