Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called

• Covalent bonds
• Ionic bonds
• Polar bonds
• Hydrogen bonds

The property of water shown allows it to —

• freeze faster than it boils due to sharing metallic bonds

• support floating objects due to forces between covalent bonds

• remain stable due to electrons forming ionic bonds

• be both cohesive and adhesive due to hydrogen bonds

Humans get most of their energy (fast, immediate energy) from eating what type of food?

• protein

• carbohydrates

• lipids

• meat

Water is polar because...

• The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
• The molecule has two poles, at which the it is colder than other regions of the molecule.
• The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.
• The water molecule is neutral.

What are the four macromolecules?

• proteins, nucleic acids, carbohydrates, and lipids
• monosaccharides, lipids, polysaccaharides, and proteins
• RNA, DNA, proteins, and carbohydrates
• proteins, DNA, RNA, and steroids
