  6. 13. a measurement of the amount of matter something has.
  7. 15. system, the system that provides structure and support to the body, stores minerals, creates blood cells, protects your internal organs, and helps the body move.
  8. 17. a part of a chromosome in a cell that controls a particular characteristic such as height or eye color. They are passed from parents to their offspring.
  9. 19. a large group of stars and matter held together by gravity.
  10. 20. system, the collection of planets and their moons, along with other celestial bodies, that orbit the sun. Also a similar system orbiting a different star.
  11. 23. a tropical cyclone storm that forms in the Atlantic and Northeast Pacific Oceans, bringing winds over 74 miles per hour, rain, thunder and lightning.
  12. 25. the curved form some types of energy, such as heat, light and sound, take as they move through space.
  13. 27. the movement of small pieces of rock or sediment due to wind, water, gravity and other natural forces.
  14. 29. an influence or power that can cause a change in an object or system.
  15. 30. the physical substance that everything is made of.
  16. 31. in the electromagnetic spectrum, the invisible waves next to violet light that have shorter wavelengths than those of violet light. This type of ray can cause suntan and sunburn.
  17. 32. chain, a series of living things in which each uses the one below it as a food source.
