Question

a. covalent bonds
b. van der waals forces
c. hydrogen bonds
d. ionic bonds
match each statement to the macromolecule that it describes or that best fills the * blank.

1. dna and rna are types of _.

a. lipids
b. proteins
c. nucleic acids
d. carbohydrates

Explanation:

1. For the first question, the dotted lines in the diagram represent hydrogen - bonds which are a type of dipole - dipole interaction. Covalent bonds are solid lines representing direct sharing of electrons between atoms. Van der Waals forces are weaker and more general intermolecular forces. Ionic bonds involve the transfer of electrons and attraction between ions.
2. For the second question, DNA and RNA are well - known types of nucleic acids. Lipids are fats and related molecules, proteins are made of amino acids, and carbohydrates are sugars and starches.

Answer:

1. c. Hydrogen bonds
2. c. Nucleic Acids
