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.

1. Decomposition of living matter for consumption.






2. Is a special protein that acts as a catalyst for organic reactions.

4. The destruction of gametes - (sex cells such as sperm and eggs).






5. Layer that will become the gut lining as well as some accessory structures.

8. The preservation of the integrity of genetic information from one generation to another.






9. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






10. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.






11. Some energy is lost as heat and becomes unusable.






12. 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.






13. Absorb a photon of light and is found in the grana of the chloroplast.






14. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






15. The phyla composed of segmented worms.






16. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






17. Inorganic phosphate






18. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






19. 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.






20. An orienting response to light.






21. Is the sugar that lactase acts upon.






22. Is a packet of digestive enzymes that destroy cellular wastes.






23. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






24. Anabolism






25. Mitochondria - they constitute the center of cellular respiration.

33. The vocal cords are found in the larynx.






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






35. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






36. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.

42. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






43. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






44. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.
