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. In DNA Guanine pairs with...






2. 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).






3. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






4. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






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






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






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






8. Respiratory organs within insects






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






10. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.






11. This is a carboxyl group and is the signature group found within organic acids.






12. All store energy within their chemical bonds.






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






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






15. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






16. Some enzymes contain a __________ component that is essential to their functions.






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






18. Inorganic phosphate






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






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






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






22. The phyla composed of segmented worms.






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






24. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).






25. 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.






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






27. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.






28. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






29. Controls olfactory lobes (smell)






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






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






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






33. High temperatures






34. 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.






35. Stood upright before there was an increase in brain size.






36. Internally generated patterns of body functions - including hormonal signals - sleep - blood pressure - and temperature regulation - which have approximately a 24-hour cycle and occur even in the absence of normal cues about whether it is day or nigh






37. 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.






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






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






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






41. 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.






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






43. In both living and non-living environments.






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






45. 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.






46. 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.






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






48. An enzyme is unaffected by the reactions it catalyzes






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






50. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting
