Front

What is the property of water that allows lake life to survive winter?

Back

Less dense as solid

Front

What property of water is responsible for water movement up the stem of plants?

Back

Adhesion and cohesion

Front

Where are hydrogen bonds found in proteins?

Back

Between backbone

Front

Where are hydrogen bonds found in nucleic acids?

Back

Between nitrogenous bases

Front

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

Back

Cohesion

Front

Define cohesion in the context of water.

Back

Cohesion is the attraction between molecules of the same substance, which in water leads to surface tension.

Front

Define adhesion in the context of water.

Back

Adhesion is the attraction between molecules of different substances, which helps water to stick to other surfaces.

Front

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

Back

Water's high specific heat allows it to absorb and release heat without significant temperature changes, stabilizing climates.

Front

Explain how hydrogen bonds contribute to water's unique properties.

Back

Hydrogen bonds create a network of interactions that give water its high surface tension, specific heat, and solvent capabilities.

Front

What is the role of hydrogen bonds in protein structure?

Back

Hydrogen bonds stabilize the secondary and tertiary structures of proteins.
