<span>the positive feedback mechanisms used to accelerate the output that is created by an already activated stimulus during homeostasis, the positive feedback moves levels out of the normal ranges it should usually be found. From this explanation the view provided by the positive feedback mechanism is a negative useless mechanism, but one importance of this mechanism is that it help in the bodies accumulation of blood platelets. Therefore it acts in the healing of tears and breaks in blood vessels as the blood clots.

Answer:
The correct answer will be option-C
Explanation:
In an organism, the mechanism of gas exchange depends on the partial pressure and total pressure of the gas. Partial pressure is the pressure of the gas exerted by a single type of gas in a mixture of gases and this pressure determines the movement of gases in the system.
The diffusion of the oxygen from the alveoli to blood capillaries depends on the partial pressure as the partial pressure of oxygen is high in alveoli measured about 104 mmHg compared to the capillaries measured about 40 mmHg.
This difference in the pressure generates pressure gradient which leads to the movement of the oxygen from alveoli to the capillaries as the movement takes place from higher to lower concentration gradient.
Thus, Option-C is the correct answer.
<span>Mile Run/Walk - 7 minutes, 42 seconds
Body Composition/BMI - 5 ft 6/142lbs/22.9 BMI
Aerobic Capacity - 41.0
Sit and Reach 30
Curl-Ups 24
Trunk Lift 18
Push-ups 23
1.. I think I am in average shape but was disappointed. I will shorten my mile walk/run and work to run the entire time. I need to build up my stamina a little more.
2. I plan to start this exercise routine three times a week so I can build up my strength and endurance. I would like to be able to run a mile in five minutes. As I keep working on the strengthening exercises, I will get stronger and be able to increase my numbers. I should get to 50 sit and reach's and 30 push ups. And, since my aerobic capacity is only 41, this exercise program should bring me up to a 42 or 43.
