The r group or side chain of the amino acid glutamic acid is hydrophilic. the r group of the amino acid valine is hydrophobic. where would a researcher expect to find these amino acids in three-dimensional structure of a protein

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.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!
