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 the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






2. Carbon - Hydrogen - Oxygen - and Nitrogen






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






4. This is a carboxyl group and is the signature group found within organic acids.






5. Covalent bonds






6. The sharp boundary of an ecosystem.






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






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






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






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






11. In DNA Guanine pairs with...






12. Engages in both passive and active transport.






13. Is the organelle where cellular reproductive processes occur.






14. 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






15. Is the process that releases energy for use by the cell.






16. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






17. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






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






19. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






20. Contains organisms that are multicellular eukaryotes including molds and mushrooms.






21. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






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






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






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






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






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






27. The phylum of insects (bees).






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






29. Transfers water and does not require sieve plates to allow nutrients through.






30. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






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






32. 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).






33. The size of a cell is limited by the ratio of its surface area to volume.






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






35. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






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






37. High temperatures






38. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






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






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






41. The total amount of genetic information available for a given species.






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






43. (of some plants or fungi) feeding on dead or decaying organic matter






44. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






45. Disease causing






46. Is the number of organisms that can be supported within a particular ecosystem.






47. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






48. 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.






49. 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.






50. Nonvascular plants such as mosses which lack tissue for conducting food or water.
