How does the body maintain the equilibrium between oxygen and hemoglobin at high altitudes?
mario62 [17]
Individuals who are both born and raised in high altitudes will have their bodies re-establish equilibrium shift by producing more hemoglobin, which allows for more oxygen to be bound to the heme protein and thus cause an equilibrium shift to the right.

A person purchases a bag of potato chips that was sealed in San Francisco, CA where the elevation is 50 feet above sea level and
bogdanovich [222]

Hello, I Am BrotherEye

Answer:

As the atmospheric pressure decreases with increase in altitude, when a sealed bag of chips is taken to higher altitude then the pressure of the gases inside the bag become greater than the outer atmospheric pressure and apply pressure on the side covering of the chips bag due to which the chips bag expand.

Explanation:

Atmospheric pressure decreases with increasing altitude. Let's assume you tie up a bag at sea level altitude (with little air inside). That air inside the bag is at 1atm as long as you're at sea level.

Now you start going up, your altitude increases and atmospheric pressure decreases (remember what I said in the beginning about atmospheric pressure decreasing with increasing altitude?).

Let's say you reach an altitude where the atmospheric pressure is 0.5atm, the force acting inside the bag which is pushing it outward is now greater than the force acting on it which is pushing it inward (1atm>0.5atm). As a result, the air inside the bag will push the sides of the bag outward, thus inflating it to a point where the pressure inside the bag becomes 0.5atm or the bag stops stretching.

For the same reason, if you bring the same bag down and take it too deep into the earth (at an altitude lower than sea level) or if you inflate the bag at a very high altitude and bring it down to sea level, it will deflate.

Best Of Luck

The mass of an erlenmeyer flask is 85.135 g. after 10.00 ml of water is added to the flask, the mass of the flask and the water
BARSIC [14]
Subtracting the mass of (flask+water) from the empty flask gives:
95.023 g - 85.135 g = 9.888 grams of water
Dividing this by the given volume of 10.00 mL water gives:
9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water
Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.
