Answer: A. sis of two amino acids, forming a peptide bond with the release of water

Explanation: Molecule Evolution is a term used to explain the changes that has taken place as organisms evolve from one generation to the next.Molecular evolution is connected with the Amino acid sequence and synthesis as every ancestor of man have certain closely related or changes which must have caused evolution to take place. the formation of peptide bonds from amino acids with the release of water is the closest option Scientists can use to explain the evolution of man.

You have been working to develop a new fictitious compound in the lab. Determine the amount in units of moles​ [mol] of 20 grams
vodomira [7]

From the chemical formula the total mass of the compound can be determined. The mass of the 1 mole of the compound is its molar mass. The atom by which the molecule is generated, the mass of these atoms are expressed in terms of amu or atomic unit mass, but after formation of a molecule in a particular ratio the mass of each of the atom becomes the total molecular weight of the generated molecule. In this case the molecule posses three atoms X, Y and Z which are in a ratio of 2:2:7. Thus the chemical formula of the compound can be written as X_{2}Y_{2}Z_{7}.

So the total mass of the compound in amu is {(2×47)+(2×42)+(7×16)} = {94+84+112}=290 amu.

Thus 1 mole of the compound contains 290 amu or 290 g  by mass.

Henceforth 20 gram of the compound is equivalent to  (20/290) = 0.068 mole.

Which of the following properties of a protein is least likely to be affected by changes in pH? Tertiary structure Primary struc
chubhunter [2.5K]

Answer:

Primary structure is the correct answer.

Explanation:

  • The primary structure is the simple level of protein structure.
  • Primary structure is a basic amino acids sequences in a protein.
  • In the primary structure, amino acids are attached together by a covalent bond.
  • Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains
  • Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.
