WebMar 26, 2016 · If molecules can pass through the plasma membrane without using energy, the molecules are using passive transport. Helping the molecules across: Active transport Sometimes, the molecules are just too big to easily flow across the plasma membranes or dissolve in the water so that they can be filtered through the membrane. WebMolecules (or ions) will spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space. (When molecules move in this way, they are said to move down their concentration gradient, from high concentration to low concentration.) ear trumpet for hearing

WebIn a plasma, some electrons have been stripped away from their atoms. Because the particles (electrons and ions) in a plasma have an electrical charge, the motions and behaviors of plasmas are affected by electrical and magnetic fields. This is the main difference between a gas and a plasma. WebApr 1, 2024 · Matter occurs in four states: solids, liquids, gases, and plasma. Often the state of matter of a substance may be changed by adding or removing heat energy from it. For example, the addition of heat can melt ice into liquid water and turn water into steam.
