2. The loutermost layer of the earth.






3. 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.






4. Small proteins that stimulate viral resistance in cells.






5. An kinterstellar cloud of dust and gas.






6. Rings that show how many years a tree has been growing. The thickness of the rings may reveal other information about climatic conditions.

8. A disease related to lower levels of insulin.






9. Different versions of a gene in a population.






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

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






17. The process in which a diploid cell divides to form haploid cells.






18. The process by which gas reverts back to liquid phase.






19. Reproduction involving only one parent.






20. Light emission from the upper atmosphere that appear in many shapes and colors.






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

34. A mammal whose young crawl into it's mothers pouch to complete development.






35. Long term patterns of temperature - humidity and amount of sunshine.






36. A visible group of water or ice particles in the atmosphere.






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






38. A ridge built in water by organisms such as coral.






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

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






46. The process by which seeds develop into seedlings.






47. A rod - shaped bacteria.
