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






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






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






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






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






7. Super-class of vertebrae including organisms with jaws.






8. Covers and protects the leaf.






9. 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






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






11. Contain one celled eukaryotes such as algae and protozoa.






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






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






14. 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.






15. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






16. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






17. Cleave strands of DNA segments at certain sites.






18. The phyla of sponges.






19. 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.






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






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






22. The phylum of insects (bees).






23. Controls hunger and thirst






24. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






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






26. Breaking down






27. In both living and non-living environments.






28. When the water concentration inside and outside the cell is equal - It is said to be in an...






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






30. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






31. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.






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






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






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






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






36. An enzyme is unaffected by the reactions it catalyzes






37. The phyla of round worms.






38. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






39. Channels is cell membranes that carry water between cells.






40. Protein synthesis






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






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






43. 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.






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






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






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






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






48. 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.






49. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






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