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






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






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






4. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






5. Ended with the extinction of the dinosaurs.






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






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






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






9. An enzyme is unaffected by the reactions it catalyzes






10. Engages in both passive and active transport.






11. Are easily converted to ATP - but the main energy products of the Krebs cycle liberate electrons then used in the electron transfer reactions.






12. 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.






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






14. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






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






16. The process of forming eggs and sperm cells in the reproductive organs.






17. 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.






18. Synthesis






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






20. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






21. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






22. In DNA Thymine pairs with...






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






24. Controls olfactory lobes (smell)






25. Super-class of vertebrae including organisms with no jaws.






26. 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.






27. 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.






28. Controls balance and muscle coordination






29. Is the outermost layer of cells of the stem.






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






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






32. 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.






33. 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.






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






35. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






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






37. Layer that will become the skin - some endocrine glands - and the nervous system.






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






39. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






40. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






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






42. 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.






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






44. Contains optic lobes - controls sight.






45. 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.






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






47. Niche






48. The individual we recognize as an adult fern.






49. 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).






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