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 outermost of the three main layers of an embryo.






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






3. 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.






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






5. What phylum are snakes in?






6. Energy transformations that occur as chemicals are broken down or synthesized within the cell.






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






8. Cleave strands of DNA segments at certain sites.






9. 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.






10. Secretes insulin to lower blood sugar and maintain equilibrium. A person eats three candy bars. Within minutes this endocrine gland affects blood-glucose homeostasis.






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






12. 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.






13. Is weaker than ionic - covalent - disulfide - or double bonds.






14. Is the waxy protective outer coating of leaves.






15. Controls olfactory lobes (smell)






16. Is an ion that binds to an enzyme making it more able to catalyze a reaction.






17. Is found on the stem between nodes.






18. Is the sugar that lactase acts upon.






19. All store energy within their chemical bonds.






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






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






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






23. The solid mass of cells resulting from the cleavage of the ovum before the formation of a blastula.






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






25. Are the organelles where cellular respiration occurs.






26. 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.






27. A cell will only remain stable if the surface area of the plasma membrane maintains a __________ with the volume of the cytoplasm.






28. 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.






29. Respiratory organs within insects






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






31. Mass extinctions promote diversification because _______________ - making conditions favorable for the establishment of new - diverse species.






32. Is a substance that changes the speed of a reaction without being affected itself.






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






34. Has extreme cold temperatures - low precipitation - modified grassland - perma-frost - a short growing season and some plants and animals.






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






36. 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






37. 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.






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






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






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






41. A hydrogen bond involves the ________________ and can be easily broken.






42. 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.






43. In both living and non-living environments.






44. Inorganic phosphate






45. 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






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