In this animated object, learners examine processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.
In this animated object, learners examine water molecules moving through a semipermeable membrane.
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
Explore what passive transport diffusion is and how it moves water through a membrane.
The learner will identify active and passive voice and distinguish between the two.
In this learning activity you'll evaluate the immune response including active, passive, natural, and artificial immunity.
