If the partial pressure of oxygen outside of a cell is 100 mmHg and the partial pressure of oxygen inside of a cell is 25 mmHg,
mrs_skeptik [129]

" There will be a net movement of oxygen from outside the cell to inside the cell " Statement is True.

Explanation:

The partial pressure for oxygen in alveoli is greater under normal circumstances, and oxygen moves neatly into the blood. In addition, the partial carbon dioxide pressure throughout the blood usually is higher, such that carbon dioxide migrate clearly into the alveoli.

The few common molecules which can traverse the cell membrane by absorption (or diffusion of a sort recognized as osmosis) are water, carbon dioxide and oxygen. Metabolism is typically oxygen-needed, which is lowest in the cell within the animal and plant, so that net oxygen flows to the cell.

What is the mass of ether(0.71) which can be put into a beaker holding 130ml
UkoKoshka [18]
D=m/v    ⇒ m=d*v

d=density
m=mass
v=volume

d(ether)=0.71 gr/cm³=0.71 gr/ ml
v=130 ml

m=d*v
m=0.71 gr/ml*(130 ml)=92.3 g

Solution: m=92.3 g
