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.
Mitochondria, plastids and chloroplast all are surrounded by a double membrane
Answer: Moving from red light to violet light, the energy increases. From equation 1 and 2, we say that energy is directly proportional to frequency and inversely proportional to wavelength.
Reciprocal. I hope this helps
