2. The graph shows the rate of reaction of salivary amylase at different temperatures.
What does the graph show at point X?
The enzyme has stopped working.
The reaction is nearly completed.
The reaction rate is controlled by pH.

4. Water is taken in through the roots and lost from the leaves of tall trees.
What enables this to happen?
active transport by the xylem vessels
pressure from the roots
translocation in the phloem
transpiration loss from the leaves
5. The diagram shows a section through a red blood cell.
How is the structure of the cell related to its function?
The cell has no nucleus to use up oxygen.
The cell membrane has a small surface area in relation to volume.
The cytoplasm contains haemoglobin.
The flat structure makes it easier to be carried through arteries.

time X-focusing on a nearby object, time Y-focusing on a distant object
time X-looking at a bright light, time Y-looking at a dim light
time X-looking at a dim light, time Y-looking at a bright light
8. To which environmental stimulus is a plant root responding when it grows downwards
a decrease in soil water content
light falling on the leaves of the plant
rising temperature
the force of gravity
9. What is an advantage of asexual reproduction compared with sexual reproduction?
A specific disease is less likely to spread throughout the whole population.
It increases variation in the offspring.
It produces offspring more rapidly.
It requires two parents.

A
B
C
D
13. The flow diagram shows the consequence of the overuse of fertilisers on farm land.
