Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.Where are fossils found?

In water In metals In sand In rock

1/5

Q2.Which of the following is NOT a way that fossils form?

Parts of the organism that decay get replaced by minerals The organism decays completely Some of the conditions needed for decay are missing Traces of the organism remain

2/5

Q3.How did this fossil form? (Image credit: CCO public domain - Petr Kratochvil -A shell fossil)

Parts of the organism that decay get replaced by minerals The organism decays completely Some of the conditions needed for decay are missing Traces of the organism remain

3/5

Q4.Tick TWO ways the fossil record provides evidence for evolution

Select two (2) boxes

It shows that animals have bones It shows how some species have evolved from a common ancestor It shows how species have changed over time It does not show soft-bodied organisms It is millions of years old

4/5

Q5.Tick THREE reasons why we cannot be certain of how life developed on Earth

Select three (3) boxes

Many fossils have been destroyed by geological activity Soft-bodied organisms rarely leave fossils The fossil record shows how species have changed on Earth The fossil record shows us how closely related species are Some fossils may not have been discovered yet

Q4.How frequently can some bacteria reproduce in optimal conditions?

Every minute Every 20 minutes Every week Every year

4/5

Q5.Tick THREE ways the development of more resistant strains could be reduced.

Select three (3) boxes

Use more antibiotics in agriculture Use less antibiotics in agriculture Do not take antibiotics if you have a non-serious condition Only take antibiotics if you have a viral condition If prescribed antibiotics, complete the full course If prescribed antibiotics, stop taking them as soon as you feel better.
