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 phylum of insects (bees).






2. 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.






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






4. 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.






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






6. Refers to the birthrate of a population.






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






8. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.






9. Controls olfactory lobes (smell)






10. The transfer of electrons.






11. Is the waxy protective outer coating of leaves.






12. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






13. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






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






15. The large brain and upright posture of Homo Sapiens...






16. 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






17. Engages in both passive and active transport.






18. 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






19. The phyla of round worms.






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






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






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






23. An orienting response to light.






24. Are cells involved in immunity and are produced in bone marrow as stem cells.






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






26. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






27. In DNA Thymine pairs with...






28. The pituitary gland.






29. The systematic search for individuals with a specific genotype in a delineated population.






30. In both living and non-living environments.






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






32. Plants and animals obtain usable nitrogen






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






34. 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






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






36. Breaking down






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






38. A hydrogen bond involves the ________________ and can be easily broken.






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






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






41. 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.






42. 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.






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






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






45. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






46. Is a substance that changes the speed of a reaction without being affected itself.






47. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






48. High temperatures






49. Is found on the stem between nodes.






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