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. Is very rare and is not absorbed by plant leaves. Phosphorous is nearly always found in solid form.






2. 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.






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






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






5. Is a kingdom that includes algae and protozoa.






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






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






8. The systematic search for individuals with a specific genotype in a delineated population.






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






10. When stems bend toward the light it is due to _____________ the hormone auxin - in response to light - migrates from the light to the dark side of the shoot tip. The cells on the dark side now contain more auxin - which causes the cells on that side






11. What phylum are snakes in?






12. 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






13. Nonvascular plants such as mosses which lack tissue for conducting food or water.






14. Algae and Protozoa belong to the kingdom...






15. Developed by the German scientists Schleiden and Schwann - States that all living things are made of cells - cells are the basic units of life - all cells come from pre-existing cells.






16. Are produced when water passes through the cell membrane by osmosis from an area of higher concentration to an area of lower concentration - to equalize water concentration.






17. Has an equal (50%) chance of being passed from a carrier mother to a son or a daughter.






18. Is a disease caused by lack of vitamin C in which the body is unable to build enough collagen (a major component of connective tissue).






19. Are cells involved in immunity and are produced in bone marrow as stem cells.






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






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






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






23. Contain one celled eukaryotes such as algae and protozoa.






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






25. Niche






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






27. 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.






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






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






30. The phylum of insects (bees).






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






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






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






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






35. 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.






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






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






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






39. 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






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






41. Controls balance and muscle coordination






42. 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






43. Covers and protects the leaf.






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






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






46. The individual we recognize as an adult fern.






47. The sharp boundary of an ecosystem.






48. Controls olfactory lobes (smell)






49. The vocal cords are found in the larynx.






50. Contains organisms that are multicellular eukaryotes including molds and mushrooms.
