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






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






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






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






5. 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.






6. Is found on the stem between nodes.






7. The phylum of insects (bees).






8. 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.






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






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






11. The phyla of round worms.






12. Is a kingdom that includes algae and protozoa.






13. Are the monomers that form nucleic acids - containing a sugar - phosphate group - and a nitrogenous base.






14. Is more like branching out of a tree with dead ends and new branches appearing simultaneously than like steps on a ladder.






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






16. Is the sugar that lactase acts upon.






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






18. Cleave strands of DNA segments at certain sites.






19. 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.






20. Ended with the extinction of the dinosaurs.






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






22. Is the number of organisms that can be supported within a particular ecosystem.






23. Contains optic lobes - controls sight.






24. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






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






26. Are membrane-bound organelles that contain digestive enzymes that digest dead or unused material within the cell or materials absorbed by the cell for use.






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






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






29. 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






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






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






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






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






34. 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.






35. The individual we recognize as an adult fern.






36. 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.






37. Plants and animals obtain usable nitrogen






38. Are the organelles where cellular respiration occurs.






39. Is the organelle where cellular reproductive processes occur.






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






41. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






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






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






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






45. Disease causing






46. Respiratory organs within insects






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






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






49. Nonvascular plants such as mosses which lack tissue for conducting food or water.






50. The sharp boundary of an ecosystem.
