Kidney Dailysis machine :

1. Dialysis is needed when both kidneys fail
2. it involves filtering of blood using a dailysis machine
3. the machine is connected up to a vein in the patients arm
4. the blood then passes through tube in the machine
5.urea and waste products: diffuse out and filtered blood returns to the arms
6. sugar and ions do not diffuse out of the blood into dailysis fuild.

Potometer:

It is designed to measure the rate of uptake of water in a cut shoot.

1. Set up the conditions of the experiment. Alterations to lighting (placing the plant in bright light or shadow), wind (directing a fan at the plant), and humidity (placing the plant in a humid chamber) are typical.
2. Let the bubble reach a "zero" point in the tube.
3. Measure the movement of the bubble at regular intervals and record the results.

Hope tht help :)

Mastermind:
Is Potometer in the Syllubus ?
