Question 22
22.
Explain how the fossil record gives us evidence that species have changed over time.
Include:
- How fossils are formed from dead organisms
- How scientists can work out the age of a fossil

This question is about investigating variation in a species.
A biologist wanted to find out whether taller lavender plants were wider than shorter lavender plants. The plants are usually between 30-80cm in height and width.
What two measurement would they need to take?
Question 17
17.
What piece of equipment could they use to take this measurement?
Question 18
