Permeability is the condition of
being capable of having materials flow into and out of a membrane. The
permeability of a cell membrane is determined by how easily a molecule can diffuse across the membrane. Usually,
only molecules that are fat-soluble can permeate across a cell membrane. This
is because the layer that is exposed on the linings of the cell membrane is
nonpolar and can therefore allow the fat-soluble molecule to pass through.
Answer:i dont remember what i was going to answer but if someone else doesnt answer before me i will answer in the comments
Explanation:
a)
• P = F/A
P = pressure = 630 N/m^2
F = force
A = area
F = mg = 0.50 kg x 9.8 m/s^2 = 4.9 N
m= mass
g= gravity
P = F/A
A = F/P
A = 4.9 N / 630 N/m^2 = 7.778 x 10^-3 m^2
b)
• Area of a circle = pi* radius ^2
7.778 x 10^-3 m^2 = pi* radius ^2
√(7.778 x 10^-3 m^2 / pi ) = radius
radius = 0.04976 m
Answers:
a ) 7.778 x 10^-3 m^2
b) 0.04976 m
3 pills per day for 30 days = 90 pills
3 months 90*3=270 pills
Hope that helps
