This question is 4 marks. 1) osmosis is the net movement of water 2) from an area of high concentration to an area of low concentration 3) across a partially permeable membrane 4) importance: allows cells...

When the temperature increases the activity of the enzyme increases, up until the optimum temperature. This is because increase in temperature, increases the movement of the molecules and so there is more...

There are multiple types of stimuli bodies can receive. These include light to the eye or a touch to the skin. I am going to use the example of a touch to the hand. The stimulus, a touch, is detected by r...
