1. as you trace the path of blood through the human body, tell how each exchange surface contributes to homeostasis. (an exchange surface is a region where the composition of blood is altered by substances leaving and/or exiting blood.)2. use regulation of body temperature to illustrate maintenance of homeostasis by a feedback mechanism.3. use regulation of normal blood pressure to illustrate how the nervous system and the endocrine systems are both involved in maintaining homeostasis.4. use the regulation of blood ph to illustrate that there are short-term and long-term mechanisms for maintaining homeostasis.5. use the regulation of a normal blood glucose concentration to illustrate that contrary actions of hormones maintain homeostasis.

you can answer any or all of them it would be a huge !

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.
