Back

Evaporation is the process by which water changes from a liquid to a gas, typically occurring when water is heated.

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins that act as catalysts to speed up chemical reactions in the body.

Front

What is condensation in the water cycle?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What are lipids?

Back

Lipids are a group of macromolecules that include fats, oils, and waxes, which are important for energy storage and cell structure.

Front

What is the function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and runoff.
