Verified step by step guidance

Understand the term 'hydrophobic': In microbiology, 'hydrophobic' refers to molecules that do not interact well with water. The term itself means 'water-fearing'.

Identify the nature of hydrophobic molecules: Hydrophobic molecules are typically nonpolar. This means they do not have a charge distribution that allows them to interact with polar molecules like water.

Consider the interaction with water: Since hydrophobic molecules are nonpolar, they do not dissolve easily in water, which is a polar solvent. This is because there is no attraction between the nonpolar molecules and the polar water molecules.

Evaluate the given options: Analyze each option to determine which one correctly describes hydrophobic molecules. Options that describe polar or water-loving characteristics are incorrect.

Select the correct description: Based on the understanding that hydrophobic molecules are nonpolar and do not dissolve in water, identify the option that states they are 'nonpolar water 'fearing' molecules' as the correct description.
