Question 1 of 20

1. Question
What is meant by convergent evolution?
- Where two unrelated species have similar features from evolving adaptations suited to the same environment.
- Where one species breeds with another and produces an offspring that is fertile
- Where two species with the same common ancestor are found in the same environment
- Where two unrelated species have the same niches but in different ecosystems
Correct

Incorrect
Question 2 of 20

2. Question
Which of these are used as evidence in classification?
- Biological molecules
- Body plans
- Plasma membranes
- Food sources
Correct

Incorrect
Question 3 of 20

3. Question
Why is the respiration enzyme cytochrome C used in classification?
- All respiring organisms have it but it differs amongst species
- All organism excretes it after the ornithine cycles has taken place
- All eukaryotic organism code for it but it differs amongst species
- Not all species produce it
Correct

Incorrect
Question 4 of 20

4. Question
What might it indicate if the cytochrome C primary sequences of two species are similar?
- They must be closely related
- They are actually the same species
- They will have a similar niche
- They have the same food source
Correct

Correct

Incorrect
Question 12 of 20

12. Question
What is phylogeny?
- The study of the evolutionary relationships between organisms
- The study of observable features amongst organisms

- The study of DNA amongst organisms
Correct

Incorrect
Question 13 of 20

13. Question
What is artificial classification?
- Sorting things into groups using few observable features
- Sorting things into their specific niche
- Sorting things into groups using DNA
- Sorting things into groups using ATP
Correct

Incorrect
Question 14 of 20

14. Question
Which of these does not describe artificial classification?
- Uses the primary sequence of biomolecules
- Based on only a few characteristics
- Does not reflect evolutionary relatioships
- Is stable
Correct

Incorrect
Question 15 of 20

15. Question
Which of these does not describe phylogenetic classification?

Correct

Incorrect
Question 16 of 20

16. Question
What is a common ancestor?
- An ancestor that is shared by two or more different groups of organisms
- An ancestor that had many species

- An ancestor that is shared by two families
Correct

Incorrect
Question 17 of 20

17. Question
What does monophyletic mean?

Correct

Incorrect
Question 18 of 20

18. Question
What is the difference between classification and phylogeny?
- Classification puts things into groups whereas phylogeny looks at evolutionary relationships
- Classification looks at organisms whereas phylogeny looks at species
