Explore what passive transport diffusion is and how it moves water through a membrane.
In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.
Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
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 processes that do not use ATP directly including hydrostatic pressure and facilitated diffusion with carrier proteins.
In this animated object, learners examine water molecules moving through a semipermeable membrane.
Learners read and listen to phrases in Mandarin Chinese that would be part of directions to common locations. Additional vocabulary words related to forms of transportation are also presented.
In this animated object, learners examine the mechanisms for gas exchange among the lungs, blood, and tissues.
