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






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






3. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






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






5. All store energy within their chemical bonds.






6. Subsets below the kingdom level






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






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






9. Controls olfactory lobes (smell)






10. Refers to the birthrate of a population.






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






12. 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






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






14. 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.






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






16. 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.






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






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






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






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






21. Is the waxy protective outer coating of leaves.






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






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






24. Is a kingdom that includes algae and protozoa.






25. Plants and animals obtain usable nitrogen






26. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






27. Are the organelles where cellular respiration occurs.






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






29. Anabolism






30. The vocal cords are found in the larynx.






31. The number of organisms in a given community - can be above or below the carrying capacity.






32. 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.






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






34. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






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






36. 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






37. Provide rigidity to plant cells (and some bacteria) and are not found within animal cells.






38. Is disorganized - unravelled - DNA with histones attached.






39. Stood upright before there was an increase in brain size.






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






41. Cleave strands of DNA segments at certain sites.






42. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






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






44. 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.






45. The pituitary gland.






46. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






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






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






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






50. 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.
