Final answer:
Molecules in a solution are in constant motion due to their chemical energy, this movement is influenced by factors such as mass, temperature, and environment. This is a vital concept in maintaining growth and dynamic homeostasis, including the movement of molecules across membranes. The kinetic energy of the molecules is affected by temperature, and larger molecules move slower due to their greater mass.
Step-by-step explanation:
Molecules dissolved in a solution are indeed in constant motion due to their chemical energy, so the statement is true. This motion is random and isotropic, meaning it's the same in all directions. Factors such as mass, temperature, and environment determine the rate of their movement. A clear demonstration of this molecular motion is the process of diffusion where substances move from an area of higher concentration to an area of lower concentration until they are evenly distributed. The constant motion described here is a fundamental principle in maintaining growth and dynamic homeostasis, including the movement of molecules across membranes.
Furthermore, the kinetic energy of the molecules increases or decreases when the temperature is raised or lowered, respectively. Finally, it's important to note that larger molecules move slower than lighter molecules due to their greater mass.
