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






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






3. Carbon - Hydrogen - Oxygen - and Nitrogen






4. Are the organelles where cellular respiration occurs.

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






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






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






15. 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.






16. In DNA Guanine pairs with...






17. Must be present for photosynthesis to occur - it is not used up in the process.

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






22. The transfer of electrons.






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






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






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






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






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






28. 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






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






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






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

40. Breaking down






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






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






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






44. It secretes saliva which enters the digestive tract and aids the digestive process.






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






46. All store energy within their chemical bonds.






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






48. Some enzymes contain a __________ component that is essential to their functions.






49. 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.
