I learned that your arms, your neck and your spinal cord have an effect on your posture. Therefore, it's important not only to sit up straight when sitting down but also walk not bending but in a good position.

1. Why do you not want the water to leak out of the holes? How might that change your experiment?
That changes the experiment by decreasing the percentage of accuracy not letting the person who conducted the experiment able to get accurate measurements.

2. Do you think the straws will have the same or different flow rates? Why?
Yes, I think that they will flow at different rates because they have different sizes so they will have different amounts of liquid that is able to flow through them.

3. Does water stop flowing out of the two cups at the same or different times? What does this tell you about the flow rate? Is the flow rate of a straw with a large diameter the same or different from the flow rate of a straw with a small diameter?
Since they are different sizes, they stop at different times. This tells me that they also have different flow rates as well. The straw with the larger diameter can disseminate larger amounts of liquid that the straw with the shorter diameter.

4. Based on your experiment, what do you think happens to the flow rate of blood during coronary heart disease?
Therefore, from this experiment you could conclude that if you have shorter vessel diameters, the less blood that can go through. This can eventually result in heart attacks and other detrimental states.

The most by product in the process of respiration is water. Water is actually a great part in our body as 70% of muscles are water, tears and saliva are made up of water and water helps deliver oxygen into our muscles. However, another by product would be carbon dioxide as it is an essential "guardian" to have in our blood.

Breathing is the action of inhaling oxygen and exhaling CO2 from our lungs and respiration is the process of breathing (breaking down and dissipating oxygen).
Cellular Respiration Equation: Cell Food +Oxygen -- > Energy + CO2 + Water (H2O)
