Where is there a low concentration of dye?

• at the bottom of cup
• in the color
• at the top of cup 
• no concenteraion gradient

The picture below is an example of _________________.

• osmosis
• isotonic
• diffusion
• active transport

Passive transport requires no

• concentration gradients
• osmosis
• motion
• energy

Due to the higher concentration of oxygen in the air than your blood, oxygen goes from the lungs into the red blood cells by....
