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






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






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






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






5. Anabolism






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






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






8. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).






9. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






10. 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.






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






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






13. Includes all living and nonliving components of the Earth to support living things.






14. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






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






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






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






19. 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.






20. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






21. The preservation of the integrity of genetic information from one generation to another.






22. The vocal cords are found in the larynx.






23. 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.






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






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






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






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






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






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






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






31. The phylum of insects (bees).






32. Is a phylum that contains sponges.






33. Is the earliest period of the Paleozoic era. Began with the Cambrian explosion - this explosion of life resulted in the representatives of most of the modern phyla being present.






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






35. What phylum are snakes in?






36. Controls olfactory lobes (smell)






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






38. 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






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






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






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






42. Is the organelle where cellular reproductive processes occur.






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






44. 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.






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






46. 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.






47. Is a phylum that contains jellyfish - hydra - etc.






48. Plants and animals obtain usable nitrogen






49. 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.






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