Answer:
the correct oprtion is B
Explanation:
the correct answer is b, since increasing the porosity of the contact lens allows it to work as a good method of gas exchange, simulating the lung membranes that present fenestrated capillaries that promote gas exchange. For this to happen, the permeability must always be high and therefore this is directly related to the porosity of the element with which the contact lens is made.
Surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity
