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






2. 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.






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






4. High temperatures






5. Contains many genes and is a structure comprised of linear DNA and associated proteins.






6. Contains optic lobes - controls sight.






7. Is the waxy protective outer coating of leaves.






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






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






10. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






12. 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.






13. Produce adrenaline. This hormone is a well-known constrictor of blood vessels.






14. The sharp boundary of an ecosystem.






15. Inorganic phosphate






16. The destruction of gametes - (sex cells such as sperm and eggs).






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






18. Controls balance and muscle coordination






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






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






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






22. Engages in both passive and active transport.






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






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






25. 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






26. Breaking down






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






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






29. The phylum of insects (bees).






30. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.






31. Is a kind of plain characterized by a warm climate - grassland - and seasonally dry climate conditions.






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






33. Decomposition of living matter for consumption.






34. 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.






35. Is weaker than ionic - covalent - disulfide - or double bonds.






36. Algae and Protozoa belong to the kingdom...






37. Is a coenzyme required in the synthesis of collagen.






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






39. 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.






40. 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.






41. Carbon - Hydrogen - Oxygen - and Nitrogen






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






43. 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






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






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






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






47. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






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






49. Carbon - nitrogen - phosphorous - and water. These are all recycled through biogeochemical processes.






50. May be ions or non-protein molecules - they are similar to cofactors - but differ in that they are tightly attached by covalent bonds to the enzyme - rather than being separate atoms or molecules.
