Glutamic acid (Glu) and valine (Val) are two amino acids with different molecular structures. (Glutamic acid is a strongly hydrophilic molecule, and valine is a strongly hydrophobic molecule). Why do you think switching the hemoglobin gene's sixth amino acid from glutamic acid to valine would affect the hemoglobin protein

Hemoglobin is the red color pigment that gives the red color to the blood. This pigment is responsible for the binding and transport of oxygen to the different parts of body.

The change in the amino acid from glutamic acid to the valine affects the protein structure and increases the hydrophobicity of the protein. This affects the protein folding and changes the function of the protein as protein are specific to their structures. The structure of the RBCs become sickle cell from the normal shape.

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.
