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. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






2. Contains optic lobes - controls sight.






3. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






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






5. In DNA Thymine pairs with...






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






7. An orienting response to light.






8. Disease causing






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






10. 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.






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






12. The phyla composed of segmented worms.






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






14. Breaking down






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






16. Is the sugar that lactase acts upon.






17. The phyla of round worms.






18. Enzymes are usually __________ to certain reactions.






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






20. Synthesis






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






22. Is a social behavior of an organism that is beneficial to the group at the individual's expense.






23. 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.






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






25. 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.






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






27. A suffix meaning 'to break apart.' O || ||






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






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






30. Inorganic phosphate






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






32. Respiratory organs within insects






33. Controls olfactory lobes (smell)






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






35. Subsets below the kingdom level






36. Small - green - heart-shaped gametophyte plant form of a fern that can make its own food and absorb water and nutrients from the soil






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






38. 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.






39. 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






40. The bronchi lead to the two lungs where they branch out in all directions into smaller tubules known as bronchioles.






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






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






43. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






44. High temperatures






45. Are where the sugars synthesized by photosynthesis travel through to various parts of the plant.






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






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






48. The effect of a substrate concentration on the initial reaction rate in the presence of a limited amount of enzyme: _________________ as the concentration of substrate is increased until all the enzymes are used - then the reaction rate will level of






49. The phyla of sponges.






50. A type of innate behavior (instinct.) The FAP is a preprogrammed response to a particular stimulus (known as a releaser stimulus). FAP's include courtship behaviors and feeding of young. These are not learned behaviors - they are automatically perfor
