•

The part played by the movement of substances across cell membranes in the functioning of different organs and organ systems.

•

The part played by enzymes in the functioning of different cells, tissues and organs.

•

Movements inside cells.

•

Transfers through ecosystems.

•

The transfer of substances containing carbon between organisms

•

Cells are easy to distinguish by their shape. How are the shapes of cells related to their function?

•

The transfer of substances containing carbon between organisms and between organisms and the environment.

•

Humans and microorganisms.

•

The biological importance of plants to humans.

•

The importance of hydrogen bonds in living organisms.

•

How nitrogen-containing substances are made available to and are used by living organisms.

•

Carbon dioxide in organisms and ecosystems

•

Why offspring produced by the same parents are different in appearance

•

Polymers have different structures. They also have different functions. Describe how the structures of different polymers are related to their nctions.

•

Describe how nitrogen-containing substances are taken into, and metabolised in, animals and plants.

•

Heat and many different substances are transferred within the body and between the body and the environment. Explain how surface area is linked to this transfer.

•

Inorganic ions include those of sodium, phosphorus and hydrogen. Describe how these and other inorganic ions are used in living organisms.

•

Bacteria affect the lives of humans and other organisms in many ways. Apart from causing disease, describe how bacteria may affect the lives of humans and other organisms.

•

Negative feedback in living organisms.

•

Mean temperatures are rising in many parts of the world. The rising temperatures may result in physiological and ecological effects on living organisms. Describe and explain these effects.
