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. Algae and Protozoa belong to the kingdom...






2. 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






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






5. 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.






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






7. Is the period when the cell is active in carrying on the function it was designed to perform within the organism. Cells spend much more time in interphase than in cell division.






8. Is the organelle where cellular reproductive processes occur.






9. The individual we recognize as an adult fern.






10. Is a phylum that contains sponges.






11. Ended with the extinction of the dinosaurs.






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






13. Produce seeds without flowers. They include conifers (cone-bearers) and cycads.






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






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






16. Is a kingdom that includes algae and protozoa.






17. The pituitary gland.






18. 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.






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






20. Refers to the birthrate of a population.






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






22. Are surrounded by capillaries that allow for carbon dioxide to diffuse into the lungs and oxygen to diffuse out.






23. 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






24. In both living and non-living environments.






25. Fruits that develop from a single ripened ovary (apple - olive - acorn - cucumber).






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






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






28. When the water concentration inside and outside the cell is equal - It is said to be in an...






29. Is found on the stem between nodes.






30. Occurs when an individual from an adjacent population of the same species immigrates and breeds with a member of a previously locally isolated group - resulting in a change in the gene pool.






31. 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.






32. 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.






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






34. The phyla composed of segmented worms.






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






36. Stood upright before there was an increase in brain size.






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






38. The sharp boundary of an ecosystem.






39. 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






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






41. 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






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






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






44. Inorganic phosphate






45. Biotic (living) factors such as population and food source - and abiotic (non-living) factors such as weather - temperature - soil features - sunlight).






46. The phyla of round worms.






47. The class composed of birds.






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






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






50. Some energy is lost as heat and becomes unusable.
