Back

Hydrophobic

Front

What is the significance of water being a polar molecule in biological systems?

Back

It allows for the formation of hydrogen bonds, which are crucial for many biological processes.

Front

How does the polarity of water contribute to its properties as a solvent?

Back

The polarity allows water to interact with and dissolve ionic and polar substances.

Front

What is cohesion in the context of water molecules?

Back

Cohesion refers to the attraction between water molecules due to hydrogen bonding.

Front

What is adhesion in relation to water?

Back

Adhesion is the attraction between water molecules and other substances.

Front

How does temperature affect the density of water?

Back

As water cools, it becomes denser until it reaches 4°C; below this temperature, it becomes less dense.
