- Classify the following samples as amino acid, peptide, or protein.A student carries out the following experiments and records the following observations. 1. A few drops of a solution of KOH (aq) is added to a solution of Fe(NO3)3 (aq). A red gelatinous solid forms immediately upon addition. 2. A few drops of a solution of KOH (aq) is added to a solution of NaNO3 (aq). No changes are observed. 3. A few drops of a solution of KOH (aq) is added to a solution that could contain Fe3+(aq) and/or Na+(aq) ions (the solution could contain both ions, just one ion, or neither ions). A red gelatinous solid forms immediately upon addition. Select all of the answers that are consistent with the data from those 3 experiments. Group of answer choices The unknown contains Fe3+(aq) and Na+(aq) The unknown contains Fe3+(aq) It is not possible to determine the presence of Na+(aq) from this experiment The unknown contains neither Fe3+(aq) or Na+(aq)Roam around your kitchen and collect some items that you can categorize as sources of each macromolecule. You may use the table template attached.
- Determine the number of proteins composed of 100 Amino acid... The solution read: total proteins composed of 100 nucleotides is equal to 20100 The solution should read total proteins composed of 100 Amino acids is equal to 20100 I did have someone answer me earlier about how to obtain the solution, however, I just believe there is a typo is the solution text. We are not looking for nucleotides, we are looking for Amino acids. So it should read total proteins composed of 100 amino acids is equal to 20100. If we were looking for nucleotides it would read 4100What are the most important components of a bioflim? (More than one can be chosen) A. nucleic acids B. Lipids and polysaccharides C. Glycocalyx and bacteria D. MoistureWhat protein structure is represented in either panel of the figure above? Question 11 options: a) Quaternary b) Secondary c) Tertiary d) Quinary e) Primary
