1. A muscle that pumps to circulate the blood.






2. Strong upper wind currents in a narrow stream that flow west to east in the United States. Weather patterns are related to the position of the jet stream - which changes often.






3. A way to date organic substances based on the carbon -14 remaining.






4. When the sun is directly over the equator. This date usually occurs on March 20.






5. A dry - north wind in late spring - summer - and early fall in north and central California.






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






7. 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.






8. A layer of tree bramches and other vegetation elevated above ground.






9. Fluid that circulates throughout the body of an animal - distributing nutrients - and usually oxygen.






10. A level of plant and animal classification between class and kingdom.






11. A rod - shaped bacteria.






12. `An important class of plant hormones associated with growth patterns.






13. A system for transporting nutrients and other essential materials throughout the body.






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






15. In the United States - the part of the western mountains that seperates water flowing toward opposite sides of the country.






16. A colorless - odorless gas that is important in the Earth's atmospheric greenhouse effect. Frozen CO2 is dry ice.






17. Study and interpretation of fossils.






18. A warm - dry wind on the eastern side of the Rocky Mountains.






19. That part of the body cavity between the mouth and the anus including in most animals the mouth - the pharynx - esophagus - stomach - intestine - and the anus.






20. Evidence of past life.






21. An kinterstellar cloud of dust and gas.






22. The movement up in the atmosphere of heated moisture. Thunderstorms are often caused by convection.






23. All the organisms in an area and the environment in which they live.






24. Light refracted through raindrops to form colors of a spectrum from red to blue.






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






26. The part of the gut that connects the pharynx and stomach.






27. The study of the patterns and mechanisms of the transmission of inherited traits from one generation to another.

31. Warming of Pacific Ocean seawater along the coast of South America that leads to significant weather changes in the United States.






32. The study of what causes motion.






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






34. A place whjere frsh water and seawater mix.






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

44. A protein that aids biochemical reactions.






45. Precipitation that evaporates before it reaches the Earth's surface.






46. A process through which organisms make nutrients available to cells.






47. Small proteins that stimulate viral resistance in cells.






48. 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.






49. A bundle of neurons - or nerve cells.






50. An excess or deficiency of electrons in a body.
