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. The individual we recognize as an adult fern.






2. 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.






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






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






5. Is a phylum that contains sponges.






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






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






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






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






10. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






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






12. The phyla of round worms.






13. Algae and Protozoa belong to the kingdom...






14. Disease causing






15. 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






16. Decomposition of living matter for consumption.






17. Is the organelle where cellular reproductive processes occur.






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






19. An enzyme is unaffected by the reactions it catalyzes






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






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






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






23. Is found on the stem between nodes.






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






25. Assumes that there are periods of stability during which little evolutionary change occurs - and that speciation can occur rapidly over a very short period of time.






26. An orienting response to light.






27. 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.






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






29. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






30. Super-class of vertebrae including organisms with jaws.






31. Niche






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






33. 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.






34. Are tubes constructed of a geometrical arrangement of microtubules in a pinwheel shape. Their function includes the formation of new microtubules - but is primarily to form the structural skeleton around which cells split during mitosis and meiosis.






35. 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






36. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






37. The phyla of sponges.






38. All store energy within their chemical bonds.






39. 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).






40. Refers to the birthrate of a population.






41. Synthesis






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






43. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






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






45. Controls balance and muscle coordination






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






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






48. The pituitary gland.






49. Controls hunger and thirst






50. Cleave strands of DNA segments at certain sites.
