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. Anabolism






2. High temperatures






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






4. All store energy within their chemical bonds.






5. The phyla of round worms.






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






7. Niche






8. The sharp boundary of an ecosystem.






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






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






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






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






13. Is the outermost layer of cells of the stem.






14. Covalent bonds






15. The phylum of insects (bees).






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






17. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






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






19. Veins in the leaf and are also distributed throughout the stem






20. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






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






22. Decomposition of living matter for consumption.






23. In both living and non-living environments.






24. Contain organisms that are multicellular eukaryotes including vertebrates and invertebrates.






25. Synthesis






26. 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.






27. 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






28. 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.






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






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






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






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






33. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.






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






35. Is a packet of digestive enzymes that destroy cellular wastes.






36. Breaking down






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






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






39. 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.






40. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






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






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






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






44. The pituitary gland.






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






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






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






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






49. 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.






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