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. Protein synthesis






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






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






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






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






6. Controls hunger and thirst






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






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






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






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






11. 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.






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






13. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






14. 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






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






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






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






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






19. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






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






21. 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.






22. 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.






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






24. The phyla of sponges.






25. In both living and non-living environments.






26. Mitochondria - they constitute the center of cellular respiration.


27. 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.






28. The role played by an organism in its food chain.






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






30. Enzymes are usually __________ to certain reactions.






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






32. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor






33. 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.






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






35. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






36. 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.






37. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






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






39. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






40. The phyla composed of segmented worms.






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






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






43. Is the sugar that lactase acts upon.






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






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






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






47. Synthesis






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






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






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