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






2. The size of a cell is limited by the ratio of its surface area to volume.






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






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






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






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






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






8. 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.






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






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






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






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






13. The sharp boundary of an ecosystem.






14. The transfer of electrons.






15. Layer that will become the skin - some endocrine glands - and the nervous system.






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






17. Include: Vascular tissue - including both xylem and phloem - and sieve plates existing between cells of the stem.






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






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






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






21. 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.






22. Is the organelle where cellular reproductive processes occur.






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






24. Cleave strands of DNA segments at certain sites.






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






26. Is a kingdom that includes algae and protozoa.






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






28. Decomposition of living matter for consumption.






29. The process of forming eggs and sperm cells in the reproductive organs.






30. Carbon - Hydrogen - Oxygen - and Nitrogen






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






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






33. The physical place where a particular organism lives. It must include all the factors that will support its life and reproduction.






34. Is the waxy protective outer coating of leaves.






35. Is disorganized - unravelled - DNA with histones attached.






36. High temperatures






37. Where protein synthesis occurs. They float unattached in the cytoplasm. They contain RNA that is specific to their function in protein formation.






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






40. Is the outermost layer of cells of the stem.






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






42. Refers to the birthrate of a population.






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






44. Is a special protein that acts as a catalyst for organic reactions.






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






46. Engages in both passive and active transport.






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






48. Controls olfactory lobes (smell)






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






50. Is a behavior that is learned during a critical point (often very early) in an individual's life. Imprinting enables the young the recognize members of their own species.
