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






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






3. Attaches to an enzyme and blocks the enzyme reaction rather than enhancing it - like a prosthetic group would.






4. Controls balance and muscle coordination






5. Ended with the extinction of the dinosaurs.






6. Is a special protein that acts as a catalyst for organic reactions.






7. Is the sugar that lactase acts upon.






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






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






10. Is the waxy protective outer coating of leaves.






11. The class composed of birds.






12. Anabolism






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






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






15. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






16. Is the organelle where cellular reproductive processes occur.






17. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






18. In both living and non-living environments.






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






20. The vocal cords are found in the larynx.






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






22. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






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






24. High temperatures






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






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






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






28. The phyla of sponges.






29. 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.






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






31. 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






32. 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.






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






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






35. Is a phylum that contains sponges.

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






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






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






40. Disease causing






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






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






43. Controls olfactory lobes (smell)






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






45. 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
