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 the process that releases energy for use by the cell.






2. The phyla of round worms.






3. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






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






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






6. Is found on the stem between nodes.






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






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






9. Is the waxy protective outer coating of leaves.






10. Is a phylum that contains sponges.






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






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






13. 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.






14. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






15. The lineage that led to the modern Homo Sapiens diverged from the lineage that led to the modern chimpanzee.






16. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






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






18. Refers to the birthrate of a population.






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






20. 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.






21. Niche






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






23. 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






24. 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).






25. Most fossils of Hominids are from continents other than...






26. The pituitary gland.






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






28. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






29. Covers and protects the leaf.






30. 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.






31. Has loosely packed cells that allow for gas and moisture exchange.






32. Controls balance and muscle coordination






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






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






35. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






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






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






38. Is a kingdom that includes algae and protozoa.






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






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






41. In DNA Guanine pairs with...






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






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






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






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






46. What phylum are snakes in?






47. 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.






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






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






50. High temperatures
