Water, Biomolecules, & Energy

Water molecules are attracted to one another because of their -

• ionic bond

• consistency

• polarity

• origin

When water molecules stick to one another to make a larger droplet of water, this is -

• high specific heat

• cohesion

• moderation of temperature

• expands upon freezing

Our bodies need water to metabolize fats (lipids) into energy.

• Yes

• No

• Maybe
