Bart believes that mice exposed to radio waves will become extra strong (maybe he's been reading too much Radioactive Man). He decides to perform this experiment by placing 10 mice near a radio for 5 hours. He compared

these 10 mice to another 10 mice that had not been exposed. His test consisted of a heavy piece of wood that

blocked the mouse food. He found that 8 out of 10 of the radio waved mice were able to push the wood away. 7 out

of 10 of the other mice were able to do the same.

if 8/10 radio wave mice were able to move the piece of wood, and 7/10 of non-radio wave mice were also able to move the piece of wood, then the radio waves have no effect upon the result.

Explanation:

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
