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. An opportunistic life strategy strategy. Lichens invading a bare rock area after a volcanic eruption is an example.






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






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






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






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






6. Are the organelles where cellular respiration occurs.






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






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

10. Refers to the birthrate of a population.






11. The pituitary gland.






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






13. 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.






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






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






16. In DNA Guanine pairs with...






17. Is weaker than ionic - covalent - disulfide - or double bonds.






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






19. In both living and non-living environments.






20. The phyla composed of segmented worms.






21. 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.






22. 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






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






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






25. Is a compound fruit that forms from several ovaries of separate flowers that fuse together during ripening (strawberry - or pineapple).






26. Fossilized burrows from multicellular organisms begin to appear in the geological record approximately 700 million years ago during the Precambrian period. These multicellular animals had only soft parts and could not be fossilized.






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






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






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






30. Is when expression of genetic traits is determined by weather the trait is inherited from the mother or the father.






31. It secretes saliva which enters the digestive tract and aids the digestive process.






32. Allows for the genetic code to be preserved in future generations of cells.






33. Contains optic lobes - controls sight.






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






35. This is a carboxyl group and is the signature group found within organic acids.






36. Decomposition of living matter for consumption.






37. Is a coenzyme required in the synthesis of collagen.






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






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






40. 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.






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






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






43. Contains many genes and is a structure comprised of linear DNA and associated proteins.






44. The class composed of birds.






45. 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.






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






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






48. Plants and animals obtain usable nitrogen

50. Is a phylum that contains sponges.
