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






2. A sex-linked recessive disorder carried on the x chromosome in which an individual cannot perceive certain colors.






3. 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.






4. The large brain and upright posture of Homo Sapiens...






5. 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.






6. Is the organelle where cellular reproductive processes occur.






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






8. Transparency - polarity - high specific heat - and density (lower density when solid than when liquid.).






9. Is a kingdom that includes algae and protozoa.






10. Is found in the root cap and is responsible for quick growth in the roots.






11. Engages in both passive and active transport.






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






13. Digestive enzymes - hydrochloric acid - and gastric juices which aid in digestion. The mucous secreted by the stomach protects the stomach lining from the acids and juices.






14. Anabolism






15. The phyla of round worms.






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






17. High temperatures






18. Is the sugar that lactase acts upon.






19. The preservation of the integrity of genetic information from one generation to another.






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






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






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






23. Sex-linked recessive disorder carried on the x chromosome defined by the absence of one or more proteins required for blood clotting






24. Contains optic lobes - controls sight.






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






26. Decomposition of living matter for consumption.






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






28. Layer that will become the gut lining as well as some accessory structures.






29. Controls olfactory lobes (smell)






30. Develops from the morula as a thin layer of cells surrounding an internal cavity.






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






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






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






34. 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.






35. 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.






36. Some enzymes contain a __________ component that is essential to their functions.






37. 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






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






39. Channels is cell membranes that carry water between cells.






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






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






43. The phyla of sponges.






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






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






46. Controls hunger and thirst






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






48. The number of organisms in a given community - can be above or below the carrying capacity.






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






50. Subsets below the kingdom level
