An area with a LARGE number of particles
An area with an UNEVEN number of particles
An area with no particles
The picture below is an example of _________________.
osmosis

active transport
Why does the tea move out of the tea bag and into the water?
The warm water forces it out of the tea bag
There is equal concentration of water and tea
There is a higher concentration of tea in the bag and less in the water
There is a lower concentration of tea in the bag and more in the water
What is the difference between active and passive transport?
Active does not need energy and passive uses energy
Active uses energy and passive does not need energy
