In this colorful and interactive object, learners examine the structure and function of muscle and connective tissues. A quiz completes the activity.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

Learners review the differences within the right and left parietal lobes. They answer questions based on a case study and describe a client in a second case study.

Learners test their spelling ability by identifying misspelled words from lists of words commonly used in business.

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, 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 and interactive object, learners conduct an experiment online to illustrate how a greater number of particles in a "vessel" increases osmotic pressure.

Explore what passive transport osmosis is and how it moves water through a semipermeable membrane.
