Question 1

describe diffusion non living

Answer 1

put potassium permanganate in hot water, and cold water

the colour from the potassium permanganate diffuses faster in the hot water then in the cold water

Question 2

describe osmosis non living

Answer 2

put visking tubing full of sugar solution in a beaker of water

water moves into bag and sugar solution stays in the bag

level of liquid in the tube rises

Question 3

describe diffusion living

Answer 3

cut prices of beetroot into cylinders and and them to water baths of different temperatures

the higher the temperature the quicker the beetroot colour will diffuse through the water

Question 4

describe osmosis living

Answer 4

add some potato cylinders into one beaker full of sucrose solution and some in a beaker of water

the potatoes in the sucrose will shrink and shrivel due to osmosis, water leaving

the potatoes in the water will swell as water enters the potatoes due to osmosis
