Answer 1

The correct option is B The dialysis unit has a coiled cellophane tube

Answer is option B i.e. "The dialysis unit has a coiled cellophane tube"
Dialysis is an ‘artificial kidney’ consists of a long coiled cellophane tube immersed in a water bath. The cellophane tube is semi-permeable and allows body waste to diffuse out of the blood into the water bath, while retaining the plasma proteins and blood cells, only the excess amounts of ions and glucose diffuse into the bath from the blood.
