Which of the Following is an example of how the respiratory system interacts with the circulatory system? a. The veins carry oxygen-rich blood to the different parts of the body.

b. The arteries carry blood from different parts of the body to the heart to maintain homeostasis.

c. The oxygen inhaled during respiration is carried throughout the body by blood to maintain homeostasis

d. The carbon Dioxide exhaled by the lungs is carried by the capillaries to the different parts of the body.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.

In this experiment, the was intentionally manipulated. it is the independent variable. the dependent variables that were measured were the
