Subjects : clep, science, biology
  • 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. This is a carboxyl group and is the signature group found within organic acids.

2. Covers and protects the leaf.

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

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

5. Produces the most ATP molecules - yielding 34 ATPs per glucose molecule.

6. Contains multicellular photosynthetic eukaryotic organisms including gymnosperms and angiosperms.

7. Contains optic lobes - controls sight.

8. Produce antibodies into the bloodstream that find and attach themselves to foreign antigens (toxins - bacteria).

9. 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.

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

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

12. Carbon - Hydrogen - Oxygen - and Nitrogen

13. 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.

14. 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.

15. The total amount of genetic information available for a given species.

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

17. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.

18. Plants and animals obtain usable nitrogen

19. Is the organelle where cellular reproductive processes occur.

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

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

22. 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

23. Cleave strands of DNA segments at certain sites.

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

25. Between the endoderm and ectoderm - layer that will eventually form the muscles - and organs of the skeletal - circulatory - respiratory - reproductive - and excretory systems.

26. Is a kingdom that includes algae and protozoa.

27. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size

28. 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.

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

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

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

32. Process in which elements - chemical compounds - and other forms of matter are passed from one organism to another and from one part of the biosphere to another.

33. Is a protein - which is a polymer of amino acids. They generally have the suffix -ase- like lactase.

34. The phyla composed of segmented worms.

35. Breaking down

36. The class composed of birds.

37. Subsets below the kingdom level

38. Controls balance and muscle coordination

39. 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.

40. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).

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

42. Plants that produce flowers as reproductive organs. They have two divisions - monocots and dicots.

43. Is the sugar that lactase acts upon.

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

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

46. The phyla of sponges.

47. 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

48. Is a compound fruit that develops from many ovaries of a single flower fusing together (raspberry).

49. Absorb a photon of light and is found in the grana of the chloroplast.

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