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. 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.






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






4. 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.






5. 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






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






7. Develops from the morula as a thin layer of cells surrounding an internal cavity.






8. Niche






9. An enzyme is unaffected by the reactions it catalyzes






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






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






12. A reaction that adds water to another compound. (2 hydrogens - 1 oxygen).






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






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






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






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






17. All store energy within their chemical bonds.






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






19. Are the organelles where cellular respiration occurs.






20. Synthesis






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






22. 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






23. The individual we recognize as an adult fern.






24. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






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






26. Is the outermost of the three main layers of an embryo.






27. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






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






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






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






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






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






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






34. Respiratory organs within insects






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






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

38. The phylum of insects (bees).






39. The size of a cell is limited by the ratio of its surface area to volume.






40. Contains optic lobes - controls sight.






41. The pituitary gland.






42. The pharynx is between the nasal passage and the trachea. Air passes into the body via the nasal passage - then passes through the pharynx and on to the trachea.






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






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






45. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






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






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






48. Refers to the birthrate of a population.






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






50. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of
