The Power of Water

Which of the following is a consequence of the polar covalent bonds within water molecules?

What is the main reason for the cohesion of water molecules?

How does water's adhesion to polar or charged materials impact organisms?

What is the role of water as a medium for metabolism and transport in plants and animals?

How do the physical properties of water impact animals in aquatic habitats?

Water Molecules and Cohesion

Polar covalent bonds within water molecules result in a slightly positive charge on hydrogen atoms and a slightly negative charge on oxygen atoms, leading to cohesion between water molecules.

Cohesion of Water Molecules

The main reason for cohesion between water molecules is the attraction between the slightly positive hydrogen atoms of one molecule and the slightly negative oxygen atoms of another molecule.

Adhesion of Water to Polar or Charged Materials

Water's adhesion to polar or charged materials, such as cell membranes, proteins, and minerals, affects the structure and function of cells, tissues, and organs in organisms.

Role of Water in Metabolism and Transport

Water serves as a medium for metabolism and transport in plants and animals, facilitating chemical reactions and the transportation of nutrients, oxygen, and waste products.

Impact of Water's Physical Properties on Aquatic Animals

The physical properties of water, including its high specific heat capacity, surface tension, and density, impact animals in aquatic habitats by regulating their body temperature, providing support, and affecting their buoyancy and movement.
