The diffusion time of the red blood cell to take oxygen through the membrane is 25uS.
The small capillaries in the lungs are in close contact and it takes a red blood cell 0.5 seconds to squeeze through the capillary.
The diffusion time for the oxygen across the 1 um thick membrane separating the air is given by,
t = x²/2D
Where,
t is the diffusion time,
x is the thickness of the membrane,
D is the diffusion coefficient.
Putting values,
t = (1 x 10⁻⁹)²/2 x 2 x 10⁻¹¹
t = 10⁻⁷/4
t = 25 x 10⁻⁹ seconds.
t = 25 uS.
so, the diffusion time is 25uS.

Answer:
y - 9 = -6( x - 0)
y - 9 = -6x + 0
y = -6x + 9
Step-by-step explanation:
If 3/7 are boys, then 4/7 have to be girls.
2282 / 7 = 326
326 x 4 = 1304
There are 1304 girls.
