The body tolerates a wide range of many variables such as blood glucose and sodium plasma levels. Why do you think that is there much less variation tolerated in oxygen saturation? Normal ranges:
Glucose 90-130 mg/dL
Plasma-sodium 135 and 145 (mEq/L)
Oxygen 95-100% saturation
There is much less variation tolerated in oxygen saturation because

Particle model to predict what will happen if a sharp object creates a hole in the soccer ball

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.

Which three statements represent the benefits of performing experiments using computer simulations?
