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






2. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






3. The phyla of sponges.






4. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






5. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






6. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






7. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






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






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






10. The phyla composed of segmented worms.






11. Is found on the stem between nodes.






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. The process of forming eggs and sperm cells in the reproductive organs.






14. Carbon - Hydrogen - Oxygen - and Nitrogen






15. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






16. Consists of undifferentiated cells capable of quick growth and specialization. It is responsible for elongation of the stem.






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






18. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






19. A suffix meaning 'to break apart.' O || ||






20. High temperatures






21. Contains optic lobes - controls sight.






22. Covers and protects the leaf.






23. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






24. Is a phylum that contains sponges.






25. Must be present for photosynthesis to occur - it is not used up in the process.






26. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






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






28. Anabolism






29. Ended with the extinction of the dinosaurs.






30. What phylum are snakes in?






31. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






32. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






33. When the water concentration inside and outside the cell is equal - It is said to be in an...






34. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






35. Is the waxy protective outer coating of leaves.






36. Super-class of vertebrae including organisms with no jaws.






37. Is a phylum that contains jellyfish - hydra - etc.






38. Is weaker than ionic - covalent - disulfide - or double bonds.






39. The role played by an organism in its food chain.






40. An enzyme is unaffected by the reactions it catalyzes






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






42. Controls hunger and thirst






43. The sharp boundary of an ecosystem.






44. Channels is cell membranes that carry water between cells.






45. States that where random mating is occurring within a population that is in equilibrium with its environment - the gene frequencies and genotype ratios will remain constant from generation to generation. It is a mathematical formula that shows why re






46. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






47. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






48. The vocal cords are found in the larynx.






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






50. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.
