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. 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






2. Is the control of protein synthesis. Genetic traits are expressed and specialization of cells occur as a result of the combination of proteins produced by the DNA of a cell.






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






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






5. 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.






6. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






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






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






10. High temperatures






11. 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.






12. Engages in both passive and active transport.






13. Breaking down






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






15. Anabolism






16. An orienting response to light.






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






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






19. 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.






20. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






21. The phyla composed of segmented worms.






22. 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.






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






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






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






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






27. Subsets below the kingdom level






28. In DNA Thymine pairs with...






29. 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.






30. Controls olfactory lobes (smell)






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






32. Synthesis






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






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






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






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






37. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






38. Covalent bonds






39. 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






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






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






42. 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.






43. 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.






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






45. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






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






47. Inorganic phosphate






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






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






50. Is a phylum that contains sponges.
