Across
- 5. is energy emitted from atomic activities and dispersed at high velocity through matter or space
- 6. the partial sterilization of a product, such as milk or wine, to make it safe for consumption and improve its keeping quality.
- 8. Owing to its lower energy state, UV radiation is not as penetrating as ionizing radiation.
- 9. chemical known to inactivate viruses, especially on living tissue
- 11. chemical that destroys bacteria except for endospores
- 13. Vegetative cells directly exposed to normal room temperature gradually become dehydrated.
- 14. the growth of microorganisms in the blood and other tissues
- 15. ensure the survival of bacteria in adverse environmental conditions such as nutrient deficiency (carbon and nitrogen) and overpopulation.
Down
- 1. a highly effective alternative for sterilizing materials that are sensitive to heat or chemical (very penetrating).
- 2. chemicals dissolved in pure water as the solvent
- 3. vary in sensitivity to heat, depending on microbe type
- 4. a combination of freezing and drying,preserves microorganisms in a viable state for many years
- 7. are chemical agents applied directly to exposed body surfaces, wounds, and surgical incisions to prevent vegetative pathogens
- 10. a small volume of the liquid chemical is diluted in a larger volume of solvent to achieve a certain ratio
- 12. chemicals dissolved in pure alcohol or alcohol-water mixtures
