Answer:
DNA or RNA: Nucleic acid
Starches and sugars: Carbohydrates
Antibodies: Proteins
Can be utilized for energy if sugars are not available: Lipids
Hydrophobic part of the plasma membrane: Lipids
Glucose and sucrose: Carbohydrates
Explanation:
The DNA or RNA can be described as molecules made up of nucleic acids.
Carbohydrates can be described as biological molecules made up of carbon, hydrogen and oxygen. For example, starches, sugars, glucose, sucrose etc
Antibodies can be describe as a type of proteins which provide the body with immunity.
Lipids or fats are the alternative source of energy if carbohydrates are not present.
The hydrophobic tail of the plasma membrane is made up of fatty acid molecules which are lipids.
