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






2. Is the sugar that lactase acts upon.






3. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






4. Ended with the extinction of the dinosaurs.






5. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






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






7. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






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






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






10. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






11. Is a kingdom that includes algae and protozoa.






12. Some enzymes contain a __________ component that is essential to their functions.






13. The vocal cords are found in the larynx.






14. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






15. 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.






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






17. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






18. Stood upright before there was an increase in brain size.






19. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






20. The pituitary gland.






21. Includes all living and nonliving components of the Earth to support living things.






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






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






24. Allows for the genetic code to be preserved in future generations of cells.






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






26. Breaking down






27. Refers to the birthrate of a population.






28. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






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






30. Contains optic lobes - controls sight.






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






32. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






33. Most chemical pollutants accidentally ingested by humans are __________ - mixed with broken down pigments in the bile - then bile is secreted into the small intestine - proceeds to the large intestine - and is expelled in the feces.






34. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






35. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






36. Is a coenzyme required in the synthesis of collagen.






37. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






38. There was extensive radiation of fish during the Devonian and Silurian periods within the Paleozoic Era.






39. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






40. 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.






41. Is found in the root cap and is responsible for quick growth in the roots.






42. Layer that will become the skin - some endocrine glands - and the nervous system.






43. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






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






45. Plants and animals obtain usable nitrogen






46. The phyla of sponges.






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






48. Contains many genes and is a structure comprised of linear DNA and associated proteins.






49. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






50. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).
