25 POINTS 1) Carefully pinch a piece of the balloon that represents the diaphragm between your thumb
and forefinger. (If you find this to be difficult, use a piece of tape to attach a small piece of
paper to the center of the balloon to use as a handle.) Gently pull the "diaphragm" downward.
What happens to the "lung?"

2) Use the model a few times to demonstrate the process of ventilation. Hopefully you see the
lung expand and fill with air, even slightly. (If you don't, check that everything on your model is
airtight and try again.) Why does this happen?

3) List at least two ways that this model differs from the “real” lungs in the human body.

Read this summary of a scientific theory: "cells are the most basic structural and functional units of life. all living organisms are made up of one or more cells. all cells that are alive in the world today came from pre-existing cells." which of the following would require this theory to be modified? -a.) a survey finds that a majority of people believe viruses carry out the basic processes of life. -b.) a prominent scientist says she feels strongly that one day the theory will be challenged by life on other planets. -c.) the dna of unicellular and multi-cellular organisms is shown to have many fundamental similarities. -d.) scientific observations show that microscopic organisms living in the deep ocean are not made up of cells.
