Across
- 4. A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles.
- 5. A physiological reaction of an organism used in self-protection, as against infection
- 8. Energy radiated or transmitted in the form of waves or particles.
- 9. The fibrous protein constituent of bone, cartilage, tendon, and other connective tissue. It is converted into gelatin by boiling
- 10. A substance, often a liquid such as ethylene glycol or alcohol, mixed with another liquid to lower its freezing point.
- 14. Capable of burning, corroding, dissolving, or eating away by chemical action
- 15. biological ability to perceive natural electrical stimuli
- 17. The dead body of an animal
- 18. The emission of light that does not derive energy from the temperature of the emitting body, as in phosphorescence, fluorescence, and bioluminescence
- 19. To replace (a lost or damaged organ or part) by the formation of new tissue
- 20. A wave phenomenon sharing the physical nature of sound but with a range of frequencies below that of human hearing
- 21. extremely poisonous compounds potassium cyanide and sodium cyanide
- 22. A chemical compound or substance that inhibits oxidation
Down
- 1. numerous chiefly marine invertebrates of the phylum Mollusca, typically having a soft unsegmented body, a mantle, and a protective calcareous shell, and including the snails, clams, and squids
- 2. Of, relating to, using, producing, or caused by heat
- 3. A weak attractive force between atoms or nonpolar molecules caused by a temporary change in dipole moment arising from a brief shift of orbital electrons to one side of one atom or molecule, creating a similar shift in adjacent atoms or molecules.
- 6. a skill, talent, or capacity
- 7. An infectious, usually fatal disease of warm-blooded animals, especially of cattle and sheep, caused by the bacterium Bacillus anthracis. The disease can be transmitted to humans through contact with contaminated animal substances, such as hair, feces, or hides, and is characterized by ulcerative skin lesions
- 9. The sudden formation and collapse of low-pressure bubbles in liquids by means of mechanical forces, such as those resulting from rotation of a marine propeller.
- 11. To preserve (cells or tissue, for example) by freezing at very low temperatures.
- 12. a specialized muscle or nerve cell that generates electricity, as found in an electric organ
- 13. a process whereby a young animal follows the characteristics of his or her mother after hathching
- 16. Light that is reflected or transmitted through certain media so that all vibrations are restricted to a single plane.
