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.

1. The vocal cords are found in the larynx.






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






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






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






5. Plants and animals obtain usable nitrogen






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






7. 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.

9. Is an abundant element found in protoplasm. Together with oxygen - hydrogen - and nitrogen - it composes over 90% of cellular structure.






10. Is a kingdom that includes algae and protozoa.






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






12. 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.






13. Is the sugar that lactase acts upon.






14. 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.






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






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. Are organic cofactors or coenzymes that are required by some enzymatic reactions.






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






19. Studied the relationships between traits expressed in parents and offspring and the genes that caused the traits to be expressed.






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






21. Controls olfactory lobes (smell)






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






23. Refers to the birthrate of a population.






24. Synthesis






25. Covers and protects the leaf.






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






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






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






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






30. Breaking down






31. The phylum of insects (bees).






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






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






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






35. Is a phylum that contains sponges.






36. Some patrol the blood for antigens - but are also equipped to destroy antigens. They may regulate immune responses as well.






37. The most recent and present era. It includes the radiation of flowering plants - the angiosperms.






38. In order to become an established part of an island ecosystem there must be a populations large enough to ensure _________ - a food source - a suitable habitat - and a source of moisture.






39. Approximately 7 - making it neither basic (under 7) nor alkaline (over 7).






40. The sharp boundary of an ecosystem.






41. (of some plants or fungi) feeding on dead or decaying organic matter






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






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






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






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






46. Are more closely related to Homo Sapiens than to other apes - but Homo Sapiens did not evolve from chimpanzees.






47. Is the major component of sand and is the most abundant element found in the lithosphere. It is not recycled.






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






49. 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






50. 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.
