In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

In this interactive object, learners review respiratory system terminology and then match the terms with their definitions in a drag-and-drop exercise.

Learners review a graphic summary of the three series of reactions that occur during cellular respiration and the net energy (ATP) yield of that process.

In this learning activity you'll assemble the components of a prokaryotic cell and match the names and functions with each structure.

Learners examine the different stages of maturation for red blood cells, white blood cells, and platelets. A quiz completes the activity.

In this animated object, learners examine the different phases of a cell's life.

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 activity, learners examine muscle cell contraction and relaxation and consider the role of calcium ions.
