A

C

G

Why do we classify living things?

It helps us understand how living things are related to each other.

What is natural selection?

Individuals with the advantageous characteristic survive & reproduce, this is passed onto the next generation (called 'survival of the fittest')

Is body mass an example of genetic or environmental variation?

Both!

What is complementary base pairing?

When A-T bond, and C-G bond

What did Crick and Watson do to help discover the structure of DNA?

They built the 3D model of the double helix

What happens during fertilisation?

A sperm cell swims to meet an egg cell, the cells combine and divide to develop into an embryo

What did Darwin notice about the finches living on different Galapagos islands?

Their beak shapes had adapted different depending on the type of food sources available, this gave them the best chances of survival
