What does the suffix -phoresis imply in terms of medical action?

The suffix -phoresis is derived from the Greek word "phorein," which means "to carry." In a medical or biological context, -phoresis refers to the process of carrying or transporting substances, often used in describing methods for separating components in a solution or facilitating the movement of particles. For example, in electrophoresis, charged particles are moved through a gel under an electric field, effectively "carrying" them based on their size and charge.

The other options suggest different meanings that are not associated with the suffix -phoresis. Formation relates to the creation or development of something, fear pertains to an emotional response, and "pertaining to formation" also does not connect to the idea of carrying. Understanding the root of the suffix provides clarity on its application in various medical terms and their uses in procedures or techniques involving transport or movement of substances.
