Verified step by step guidance
1
Begin by understanding the context of the problem, which involves the movement of substances in response to a chemical stimulus, specifically in the realm of acids and bases.
Consider the term 'Chemotaxis', which is defined as the movement of an organism or cell in response to a chemical stimulus. This is relevant in biological systems where cells move towards or away from certain chemicals.
Evaluate the other terms provided: 'Electrophoresis' refers to the movement of charged particles in a fluid under the influence of an electric field, 'Diffusion' is the passive movement of particles from an area of high concentration to an area of low concentration, and 'Osmosis' is the movement of water across a semipermeable membrane from a region of low solute concentration to high solute concentration.
Identify that 'Chemotaxis' is the term that specifically describes movement in response to a chemical stimulus, which is the focus of the question.
Conclude that in the context of acids and bases, 'Chemotaxis' is the correct term to describe the movement towards or away from a chemical stimulus.
