Answer

Brief Explanations:

  1. A covalent bond involves sharing of electrons between atoms, while an ionic bond is formed by the transfer of electrons from one atom to another.
  2. The molecule shown has a long - chain with a double bond and a carboxyl group at one end, which is characteristic of an unsaturated fatty acid. Saturated fatty acids have no double bonds, polysaccharides are made of sugar monomers, polypeptides are chains of amino acids, and amino acids have an amino and a carboxyl group and a side - chain attached to a central carbon.
  3. Phospholipids contain two hydrocarbon chains bound to glycerol by ester bonds. The other options do not correctly describe the structure of phospholipids.
  4. Amino acids with hydrocarbon side - chains like leucine and valine are non - polar because C - H and C - C bonds are non - polar.

Answer:

  1. electrons; transfer of electrons from one atom to another
  2. unsaturated fatty acid
  3. It contains two hydrocarbon chains bound to glycerol by ester bonds.
  4. non - polar (missing option in the original question text but this is the correct property based on the description)
