22 POINTS ! Pick a body function that requires at least two different organ systems to perform. The function can be involuntary or voluntary. Design a model that shows how these systems work together. You may want to localize the function to a specific body part. For example, running involves many muscles and bones, which may make it difficult to model. However, you can focus on a specific motion for running, such as bending the knee joint. In a paragraph, explain why it requires at least two body systems to perform the function you selected.

What are the strengths of your model?

Use your model to explain why cells are the building blocks for human bodies.

Pick one of the body parts shown in your model. How would a disease or injury to this organ affect the process you modeled? How would it affect the body as a whole?

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
