Front

What is the property of water that allows it to be less dense as a solid than as a liquid?

Back

Less dense as solid

Front

What type of bond forms between nitrogenous bases in nucleic acids?

Back

Hydrogen bonds

Front

What property of water is responsible for its high specific heat?

Back

Hydrogen bonding

Front

What is the process called when water absorbs heat and evaporates, cooling the surface?

Back

Evaporative Cooling

Front

Where do hydrogen bonds primarily exist in the backbone of proteins?

Back

Between backbone

Front

What is cohesion in the context of water?

Back

The attraction between water molecules due to hydrogen bonding.

Front

What is adhesion in the context of water?

Back

The attraction between water molecules and other substances.

Front

How does water's high specific heat benefit aquatic life?

Back

It helps maintain stable temperatures in bodies of water.

Front

What is surface tension and how is it related to water?

Back

Surface tension is the cohesive force at the surface of water that allows it to resist external force.

Front

What role do hydrogen bonds play in the structure of DNA?

Back

They hold the two strands of DNA together between the nitrogenous bases.
