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. 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






2. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






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






4. Niche






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






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






7. An enzyme is unaffected by the reactions it catalyzes






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






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






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






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






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






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






14. Is composed of an anterior and posterior lobe. The stalk of the lobe is connected to the hypothalamus. Antidiuretic Hormone (AH) is produced in the hypothalamus and stored in the posterior pituitary. Upon nervous stimulation from the hypothalamus - t






15. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.






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






17. Super-class of vertebrae including organisms with no jaws.






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






19. Is the sugar that lactase acts upon.






20. 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.






21. 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.






22. The sharp boundary of an ecosystem.






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






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






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






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






27. Ended with the extinction of the dinosaurs.






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






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






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






31. Anabolism






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






33. The phyla composed of segmented worms.






34. 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.






35. Cleave strands of DNA segments at certain sites.






36. Layer that will become the skin - some endocrine glands - and the nervous system.






37. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






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






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






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






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






42. In DNA Thymine pairs with...






43. The pituitary gland.






44. 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.






45. High temperatures






46. An orienting response to light.






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






48. Contains the chromosomes and is the site of reproduction through mitosis and meiosis.






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






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