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. Transfers water and does not require sieve plates to allow nutrients through.






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






3. What phylum are snakes in?






4. Anabolism






5. Is a phylum that contains sponges.






6. Occurs when an individual learns not to respond to a particular stimulus - for instance when a stimulus is repeated many times without consequence.






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






8. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






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






10. 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.






11. The process whereby cells build molecules and store energy (in the form of covalent chemical bonds).






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






13. The transfer of electrons.






14. The individual we recognize as an adult fern.






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






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






17. In DNA Guanine pairs with...






18. Bacteria break ammonia into nitrites - then into nitrates that are usable by plants; volcanic activity produces ammonia and nitrates that enter the soil and can be absorbed by plants; lightning reacts with atmospheric nitrogen to form nitrates that a






19. In both living and non-living environments.






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






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






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






23. Controls sensory and motor responses - and controls memory - speech - and intelligence factors.






24. Controls hunger and thirst






25. 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






26. Is comprised of all the organisms that interact within a given ecosystem whether or not it is at carrying capacity.






27. 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






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






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






30. 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.






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






32. Engages in both passive and active transport.






33. Is the sugar that lactase acts upon.






34. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






35. Is a kingdom that includes algae and protozoa.






36. Has extreme hot or cold temperatures - with very low precipitation - sandy or rocky terrain - sparse vegetation (mainly succulents) - small animals - rodents - and reptiles.






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






38. 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.






39. Occurs when two populations are geographically isolated from each other. Over time this results in the production of two separate species.






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






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






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






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






44. Breaking down






45. Is made of stacked cells connected by sieve plates that allow nutrients to pass from cell to cell. They transport food made in the leaves (by photosynthesis) to the rest of the plant).






46. Becomes available for erosion as undersea sedimentary rocks are up-thrust by volcanic activity - erosion releases it from rocks into streams where it combines with oxygen to form phosphates in lakes that are then absorbed by plants - it is recycled t






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






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






49. High temperatures






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