1. Plants that die after one growing season.






2. A cell with two copies of each chromosome.






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






4. Compounds that are fats and oils.






5. The flow of a charge.






6. Small proteins that stimulate viral resistance in cells.

8. The tissue in plants that conducts nutrients.






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






10. A relationship between organisms in which one organism benefits and the other does not die - even though the second organism may be harmed.






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






12. A protein that aids biochemical reactions.






13. In the mateamorphosis of insects - the larva becomes a pupa before it becomes an adult.






14. A temperature scale in which 1 degrees Kelvin equals 1 degree Celsius. 0 degree Kelvin is about -273 degree Celsius. Kelvin is called absolute zero because there is no movement of molecules.






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






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






17. Different versions of a gene in a population.






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

28. The process by which seeds develop into seedlings.






29. A solute that accepts protons.






30. An instrument to measure wind speed.






31. Reproductive haploid cells that combine to creat a zygote.






32. An organsim that eats meat - which includes animals - fungi - and plants.

35. A term used to describe the coiling strands of DNA molecule that resembles a spiral staircase.






36. The loutermost layer of the earth.






37. The phenomenon when refraction of light makes objects appear where they are not.






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






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






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






41. The process by which gas changes directly to the solid phase.






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






43. The reproductive parts of flowering plants.






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






45. The rate of change of an objects velocity.






46. The part of flowering plants that contains seeds.






47. The physical - chemical - and biological processes by which rock is broken down into smaller pieces.






48. The study of the interactions of organisms with their environment and with each other.






49. Fertilization of one plant by pollen from a different plant species.






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