  • 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. When the sun is highest in the sky and directly above the Tropic of Cancer 23 1/2 degrees North Latitude. This date usually falls on June 22.






2. Evidence of past life.






3. Compounds that are fats and oils.






4. An almond shaped cloud usually seen on windy days.






5. An identical copy of an organism.






6. The tissue in plants that conducts nutrients.






7. A protein that aids biochemical reactions.






8. Biological molecules that have important roles in energy metabolism and storage as well as the structure of cells and organisms.






9. Molten rock flormed in the Earth that may appear on the surface.






10. Study and interpretation of fossils.






11. A cell with one set of chromosomes - which is half the regular (diploid) number.






12. A relationship between disimilar organisms that is adventageous to one and doesn't affect the other.






13. Plants that die after one growing season.






14. The network of glands and tissues that secrete hormones.






15. Atoms of the same chemical element with a different number of neurons but the same number of protons. Isotopes of an element have the same atomic number but may not have the same mass.






16. Reproduction involving only one parent.






17. The combined cooling effect of wind and temperature. Higher wind chills indicate that a body will cool more quickly to the air temperature.

35. An organism's unique place in the environment.






36. Movement of pollen to a plant egg cell - often b y wind - bees - or other animals.






37. Multicellular organisms whose cells contain organelles.






38. The movement and collision of gas molecules in the atmosphere that can form into high or low pressure areas.






39. The fundamental unit of all life. The cell consists of an outer plasma membrane - the cytoplasm - and the genetic material (DNA).






40. The digestive tract between the stomach and anus where most nutrients are absorbed.






41. Cell division consisting of prophase - metaphase - anaphase - and telophase - that usually creats in two new nuclei - each with a full set of chromosomes.






42. An instrument that measures cloud height.






43. A malignant tumor - which forms in the skin and outside of internal organs.






44. The flow of a charge.






45. The Earth's atmosphere is primarily nitrogen and oxygen. The troposphere extends from the surface to about 10 km.; the stratosphere from 10km to 50 km.; the mesosphere from 50 km. to 80 km.; and the thermosphere is the atmosphere beyond 80 km.






46. The place on the surface of the Earth immediately above the 'focus' of an earthquake.
