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. Most fossils of Hominids are from continents other than...






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






3. A length of DNA (with corresponding histones) is responsible for the production of a certain protein that causes a particular trait to be expressed in an organism.






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






5. Breaking down






6. Are formed when the plasma membrane of a cell encloses a molecule outside the membrane - then releases a membrane bound sack containing the desired molecule into the cytoplasm. This process allows the cell to absorb molecules that are larger in size






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






8. An enzyme is unaffected by the reactions it catalyzes






9. The pituitary gland.






10. Is the outermost of the three main layers of an embryo.






11. Decomposition of living matter for consumption.






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






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






14. The cells of a developing embryo (at the gastrula stage) differentiate into layers - that will later develop into different tissues and organs - including the mesoderm - ectoderm - and endoderm.






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






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






17. What phylum are snakes in?






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






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






20. 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






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






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






23. In DNA Thymine pairs with...






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






25. In both living and non-living environments.






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






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






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






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






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






31. 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.






32. Contains optic lobes - controls sight.






33. A suffix meaning 'to break apart.' O || ||






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






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






36. Refers to the birthrate of a population.






37. The phyla of round worms.






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






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. Disease causing






41. 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.






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






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






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






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






46. Controls balance and muscle coordination






47. Chlorophyll pigments absorb photons of light - leaving the chlorophyll in a higher energy (excited) state - these then supply energy to reactions that produce ATP from ADP and Pi.






48. Proposes that those individuals within a population that are most adapted to the environment are also the most likely individuals to produce viable offspring.






49. Respiratory organs within insects






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