In this video, you'll review how every protein molecule of an organism is synthesized.

In this learning activity you'll review how every protein molecule of an organism is synthesized by that organism in a prescribed process. This activity helps students understand the fundamental life process of making protein.

In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.

Explore what proteins are, their structure, and their functions.

Students identify the various regions of the human body through video.

Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.

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

Learners follow the path of a protein food from consumption through digestion to absorption into the bloodstream.

In this video learners view the valves and chambers of the heart.

In this video, learners view the parts of an animal cell and its organelles.

In this animated object, learners read an introduction to protein structure and function.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

In this learning activity you'll examine Newton's Third Law: for every action, there is an equal but opposite reaction.

In this learning activity you'll examine force, mass, and acceleration to understand this "Law of Acceleration."

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

Learners examine the seven most common barriers to effective listening and consider suggestions for how to overcome these barriers. This interactive object contains audio.

The learner views several animations to study Newton's First Law of Motion, also known as "The Law of Inertia."

In this animated object, learners examine neutral fats, phospholipids, and cholesterol. The molecular formula and general function for each are shown.

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

Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.
