How does water help in moderating temperature in living organisms?

• Water moderates temperature in living organisms by reflecting heat effectively.

• Water moderates temperature in living organisms by increasing heat production.

• Water moderates temperature in living organisms by absorbing and releasing heat effectively.

• Water moderates temperature in living organisms by reducing heat absorption.

Why does ice float on water?

• Ice is not affected by gravity.

• Ice is more dense than water.

• Ice is less dense than water.

• Ice has a higher temperature than water.

Why is water considered a universal solvent?

• Water dissolves substances by emitting light rays

• Water can dissolve many substances due to its polar nature and ability to form hydrogen bonds.

• Water is considered a universal solvent because it contains magical properties

• Water is a universal solvent because it has a high sugar content

What is the main force responsible for the high surface tension of water?

• Hydrogen bonding

• Van der Waals forces

• Covalent bonding

• Ionic bonding

How does water's cohesion property help in transporting nutrients in plants?

• Water's cohesion property helps in the capillary action, facilitating the movement of nutrients in plants.

• Water's cohesion property results in the breakdown of nutrients in plants.

• Water's cohesion property causes nutrients to evaporate in plants.

• Water's cohesion property leads to the accumulation of nutrients in the soil.

How does water's adhesion property help in the movement of water in plants?

• Adhesion leads to water evaporation in plants, reducing overall water flow.

• Adhesion creates a barrier preventing water from entering plant tissues.

• Adhesion causes water to repel plant vessels, hindering water movement.

• Adhesion helps water stick to the walls of plant vessels, aiding in capillary action for upward movement.
