AP Bio Insta-Review Topic 1.1: Structure of Water & H Bonding

Front

What is the property of water that allows organisms to cool down through sweating?

Back

Evaporative Cooling

Front

Where are hydrogen bonds found in proteins that are exclusive to them?

Back

Between backbone

Front

What property of water helps lake life survive during winter?

Back

Less dense as solid

Front

What type of bond is present in water molecules?

Back

Covalent

Front

What property of water allows rocks to skip on a pond's surface?

Back

Cohesion

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between water molecules due to hydrogen bonding, which allows water to form droplets and enables phenomena like skipping rocks.

Front

Define adhesion in the context of water.

Back

Adhesion is the attraction between water molecules and other substances, which allows water to climb up plant roots and stick to surfaces.

Front

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

Back

Water's high specific heat allows it to absorb and retain heat, stabilizing temperatures in organisms and environments.

Front

Explain the term 'less dense as a solid' in relation to water.

Back

Water is less dense as a solid (ice) than as a liquid, which causes ice to float and insulates bodies of water, protecting aquatic life.

Front

What role do hydrogen bonds play in the properties of water?

Back

Hydrogen bonds contribute to water's unique properties, including high surface tension, cohesion, adhesion, and its ability to dissolve many substances.
