test for macromolecules

Rohan, Aria, and William are in their school's science lab, working on a project for their chemistry class. They have an iodine solution and want to test it on various polymers they found in their everyday items. Which polymer should they use to get a positive result?

• polynucleotide

• polysaccharide

• many fatty acids

• polypeptide

Abigail, Nora, and Michael are conducting a science experiment in their biology class. They are using biuret solution in their experiment. Can you tell them which macromolecule the biuret solution is indicating for?

• Carbohydrate

• Lipid

• Protein

• Nucleic Acid

Arjun, Aria, and Lily are studying for their biology exam. They come across a question about the polymer of a carbohydrate. What would be the correct answer?

During a biology experiment, Nora and Daniel were asked to identify the presence of a specific monomer using Benedict's solution. Which monomer does Benedict's solution indicate for?

• amino acid

• monosaccharide

• fatty acid

• nucleotide

Abigail and Avery are conducting a science experiment in their class. They need to test for SIMPLE sugars in a food sample. Which indicator should they use?

• Iodine

• Benedicts
