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






2. Enzymes are usually __________ to certain reactions.






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






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






5. Is the organelle where cellular reproductive processes occur.






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






7. The phyla of sponges.






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






9. Is a phylum that contains sponges.






10. Absorb a photon of light and is found in the grana of the chloroplast.






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






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






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






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






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






16. 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.






17. 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






18. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






19. 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.






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






21. An orienting response to light.






22. Is a molecule that stores information for protein synthesis and genetic coding.






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






24. Anabolism






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






26. Subsets below the kingdom level






27. Disease causing






28. Is an accidental change of the DNA sequence of the gene that can result in creating a change of trait that is not found in the parent.






29. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






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






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






32. What phylum are snakes in?






33. The trachea includes the windpipe or larynx in its upper portion - and the glottis - an opening that allows the gases to pass into the two branches known as the bronchi.






34. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.

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






37. In DNA Thymine pairs with...






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






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

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






42. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.

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






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






48. Has loosely packed cells that allow for gas and moisture exchange.






49. 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
