Question

complete the table to compare the structures of a lipid and dna. may contain a hydrophilic head and hydrophobic tails may contain three fatty acid molecules and one glycerol molecule has hydrogen bonds between nitrogenous bases

Explanation:

1. Lipids such as phospholipids have a hydrophilic head and hydrophobic tails. DNA does not have this structure.
2. Triglycerides, a type of lipid, consist of three - fatty acid molecules and one glycerol molecule. DNA is made of nucleotides and not this composition.
3. DNA has hydrogen bonds between its nitrogenous bases (A - T and C - G), while lipids do not have hydrogen - bonding between nitrogenous bases as they do not contain nitrogenous bases in the same context.

Answer:

	Lipid	DNA
May contain three fatty acid molecules and one glycerol molecule	Yes	No
Has hydrogen bonds between nitrogenous bases	No	Yes
