Someone ran an SDS-PAGE separation of a crude protein mixture product, and found a protein band at around 18,000 Dalton. It is suspected that this protein might be a mutant of a known protein. The mutant protein differs from the known protein by only the last two amino acids at the N-terminus of the peptide chain. Propose a most suitable method that can be used to determine whether this protein band is the known protein or the mutant protein. Must explain why you make this choice.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
