AP Biology Chemistry Review

Front

What property of water enables molecules to cling together as they move from the roots to the leaves of plants?

Back

Cohesive behavior: This property allows water molecules to stick to each other, facilitating the movement of water through plant structures.

Front

Why do large bodies of water not quickly fluctuate in temperature?

Back

High heat capacity: Water can absorb a lot of heat without a significant change in temperature, which helps stabilize the climate.

Front

What property of water helps to moderate Earth's temperature?

Back

Specific heat capacity: This property allows water to absorb and release heat slowly, helping to regulate temperatures.

Front

Why is carbon so important to living things?

Back

Carbon is essential because it forms stable bonds with many elements, allowing for the creation of a vast array of organic molecules.

Front

What are the compounds on the right side of a chemical equation called?

Back

Products: These are the substances formed as a result of a chemical reaction.

Front

What is the term for the attraction between water molecules?

Back

Cohesion: This is the force that holds water molecules together.

Front

What is the term for the attraction between water molecules and other substances?

Back

Adhesion: This property allows water to stick to other surfaces.

Front

What is the significance of water's high heat of vaporization?

Back

It allows organisms to cool down through processes like sweating, as it takes a lot of energy to convert water from liquid to gas.

Front

What is the role of water as a solvent in biological systems?

Back

Water dissolves many substances, facilitating chemical reactions and transport of nutrients in organisms.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are the starting materials that undergo a chemical change, while products are the substances formed as a result.
