Permeability is the condition of being capable of having materials flow into and out of a membrane. The permeability of a cell m
embrane 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. Why is this the case?

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:4. Two charged objects have a repulsive force of 0.080 N. If the distance separating the objects is tripled, then what is the new force? Explanation: The electrostatic force is inversely related to the square of the separation distance.
Assuming the light takes essentially no time to reach you, the distance at which the lightning occurred can be calculated by multiplying the speed of sound by the time it takes to hear the thunder:
