Front

What is facilitated diffusion?

Back

Facilitated diffusion is the movement of larger particles through proteins in the membrane requiring no energy.

Front

What happens to water in a hypertonic solution?

Back

Water moves out of the cell.

Front

Which body systems are primarily used while running?

Back

The respiratory and muscular systems.

Front

What is active transport?

Back

Active transport requires energy and flows from low to high concentration.

Front

What occurs when dry ice is heated from -100 °C to 30 °C at 10 atm?

Back

Melting, then boiling.

Front

Define osmosis.

Back

Osmosis is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy.

Front

What is a semipermeable membrane?

Back

A semipermeable membrane allows certain molecules to pass through while blocking others.

Front

What is the role of the respiratory system during exercise?

Back

The respiratory system supplies oxygen to the body and removes carbon dioxide.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.
