This process continues until there is an <strong>equilibrium<\/strong>, meaning the molecules are evenly distributed across the space available. Importantly, <strong>diffusion is passive<\/strong>\u2014it does not require energy\u2014and it relies entirely on the <strong>concentration gradient<\/strong> of a substance.<\/p>\n\n\n\n<p>In the situation described, we have two different dyes: <strong>orange<\/strong> and <strong>purple<\/strong>. Each dye diffuses <strong>independently<\/strong>, meaning the movement of one does not affect the movement of the other. This is typical in biological and chemical systems where different substances follow their <strong>own concentration gradients<\/strong>.<\/p>\n\n\n\n<p>We are told that:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The <strong>orange dye<\/strong> is moving from <strong>side A to side B<\/strong>, which suggests a <strong>higher concentration on side A<\/strong> and a <strong>lower concentration on side B<\/strong>.<\/li>\n\n\n\n<li>The <strong>purple dye<\/strong> is moving <strong>only from side B to side A<\/strong>, but overall, there is <strong>no net movement<\/strong>.<\/li>\n<\/ul>\n\n\n\n<p>\u201cNo net movement\u201d means that while individual molecules of purple dye may still be moving back and forth, the <strong>total amount of purple dye on each side stays the same<\/strong>. This occurs when the <strong>concentration of purple dye is the same on both sides<\/strong>\u2014an equilibrium has been reached. In such a state, <strong>random molecular motion<\/strong> still happens, but the <strong>rate of movement in each direction is equal<\/strong>, canceling each other out.<\/p>\n\n\n\n<p>Thus, the presence of <strong>equal concentration<\/strong> explains why there is no net movement of purple dye. Even though molecules still move (as molecules always have kinetic energy), they do so equally in both directions, leading to <strong>dynamic equilibrium<\/strong>.<\/p>\n\n\n\n<p>This principle is crucial in physiology, particularly in how gases like oxygen and carbon dioxide diffuse across membranes in the lungs, or how nutrients move into and out of cells.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Orange dye moves independently of purple dye.Concentration gradients exist that drive diffusion of both dyesThere is a net movement of orange dye from side A to side B.Purple dye moves only from side B to side A.
