They trap some of the long-wave radiation emitted by the Earth’s surface.

They prevent short-wave radiation from reaching the Earth’s surface.

They dissolve in rainwater to produce acid rain.

They are only produced by human activity whereas CO2 and CH4 are also produced naturally.

Any individuals in a population can be selected entirely by chance.

After a change in the environment a species will evolve adaptations to the new conditions.

If an adaptation to the environment is useful, an individual will develop it and pass it on to its offspring.

Variations amongst individuals of a population are selected by a changing environment.

Viruses can hide inside host cells.

Bacteria are recognized as pathogens but viruses are not.

The enzymes of bacteria can be inhibited by antibiotics.

Viruses are resistant to antibiotics.
