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. Is the process that releases energy for use by the cell.






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






3. 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.






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






5. 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.






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






7. Enzymes are usually __________ to certain reactions.






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






9. The role played by an organism in its food chain.






10. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






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






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






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






14. In both living and non-living environments.






15. Controls balance and muscle coordination






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






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. The transfer of electrons.






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






20. The phyla of sponges.






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






22. Is the outermost of the three main layers of an embryo.






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






24. 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.






25. Engages in both passive and active transport.






26. Is a special protein that acts as a catalyst for organic reactions.






27. The part of the earth that contains all living things - including the atmosphere (air) - the lithosphere (earth) - and the hydrosphere (water).






28. Is found on the stem between nodes.






29. Can be accounted for by the theory of punctuated equilibrium. The fossil record shows periods of stability with regard to appearance and disappearance of species as well as periods of sudden change.






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






31. The individual we recognize as an adult fern.






32. Is the sugar that lactase acts upon.






33. Covalent bonds






34. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






35. What phylum are snakes in?






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






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






38. Most fossils of Hominids are from continents other than...






39. Is composed of a double layer (bilayer) of phospholipids with protein globules imbedded within the layers. The construction of the membrane allows it to aid the function of the cell by permitting entrance and exit of molecules as needed by the cell.






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






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






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






43. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






44. 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






45. Super-class of vertebrae including organisms with no jaws.






46. Process of breaking down complex materials (foods) to form simpler substances and release energy.






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






48. Is secreted by the adrenal cortex to promote sodium reabsorption in the kidney.






49. Carbon - Hydrogen - Oxygen - and Nitrogen






50. The phyla composed of segmented worms.
