IB Bio water practice A1.1

Front

What are the three main properties of water?

Back

liquid, high specific heat capacity, surface tension

Front

Explain the concept of polarity in water molecules.

Back

Uneven distribution of electrical charge within the molecule

Front

How does hydrogen bonding contribute to the unique properties of water?

Back

Hydrogen bonding in water molecules leads to high cohesion, surface tension, and the ability to absorb heat.

Front

Why is water considered a universal solvent?

Back

Water is considered a universal solvent because it has the ability to dissolve a wide variety of substances due to its polar nature.

Front

How does water play a crucial role in biological systems?

Back

Water is the main component of cells and is involved in various metabolic processes.

Front

What is the significance of the high specific heat capacity of water in living organisms?

Back

Temperature regulation and stabilization of internal body temperature.

Front

Describe the process of cohesion and adhesion in water.

Back

Cohesion is the attraction between water molecules, causing them to stick together. Adhesion is the attraction between water molecules and other substances, causing them to stick to surfaces.

Front

What is the role of water in maintaining temperature regulation in organisms?

Back

Water acts as a coolant and facilitates heat transfer through processes like sweating and evaporation.

Front

Explain the importance of water in the transport of nutrients and waste in living organisms.

Back

Water is essential for the transport of nutrients and waste in living organisms.

Front

How does water participate in chemical reactions within cells?

Back

Water acts as a solvent and facilitates transport and metabolic reactions.
