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. 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






2. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






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






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






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






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






7. Is disorganized - unravelled - DNA with histones attached.






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






9. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






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






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






12. The individual we recognize as an adult fern.






13. 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.






14. Controls hunger and thirst






15. Inorganic phosphate






16. Ended with the extinction of the dinosaurs.






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






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






19. 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






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






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






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






23. The class composed of birds.






24. Engages in both passive and active transport.






25. Is the outermost of the three main layers of an embryo.






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






27. 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






28. Cleave strands of DNA segments at certain sites.






29. Is a phylum that contains sponges.






30. 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.






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






32. Is found on the stem between nodes.






33. Veins in the leaf and are also distributed throughout the stem






34. Is a special protein that acts as a catalyst for organic reactions.






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






36. 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.






37. 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.






38. Controls olfactory lobes (smell)






39. Is the sugar that lactase acts upon.






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






41. High temperatures






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






43. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






44. Covalent bonds






45. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






46. The phyla composed of segmented worms.






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






48. 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.






49. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






50. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.
