CLEP Biology

Subjects : clep, science, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Layer that will become the gut lining as well as some accessory structures.






2. The pituitary gland.






3. Contain one celled eukaryotes such as algae and protozoa.






4. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.

8. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






9. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






10. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






11. What phylum are snakes in?






12. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.

14. It secretes saliva which enters the digestive tract and aids the digestive process.






15. Plants and animals obtain usable nitrogen






16. Process of breaking down complex materials (foods) to form simpler substances and release energy.






17. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






18. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.
