When blood is flowing through a vena cava, which main blood vessel will it flow through next?

How does insulin move from the pancreas, where it is produced, to the cell where it acts?

The graph shows the energy released by two animals through respiration as the external temperature changes.

Which conclusion can be drawn from the graph?

The graph shows changes in the volume of air in the lungs of a person at rest, over a period of 30 seconds.

Which graph shows changes in the volume of air in the lungs of the same person immediately after they have done five minutes of vigorous exercise?

Four word equations are shown.
P carbon dioxide + water → glucose + oxygen
Q glucose + oxygen → carbon dioxide + water
R glucose → lactic acid
S glucose → alcohol + carbon dioxide

The diagram shows a simple reflex arc.

What is the correct order of events after the knee is tapped?

The graph shows the effect of an antibiotic treatment on bacterial populations in the blood. What conclusion can be drawn from the graph?

What are involved in reproduction in both animals and plants?

The diagram shows different parts of the female reproductive organs where different methods of birth control can be used.
Where should a diaphragm be placed before intercourse if a couple do not want a baby?

The diagram shows an experiment on germination. Groups of test-tubes were set up as shown. The groups were placed in different conditions.
