- 2. Which of the following statements is true regarding steam sterilization? a. It is a universal technique, applicable to a product of any nature. b. At the same temperature, usually more effective than dry heat. c. Steam sterilization is amenable to a continuous workflow. d. The purpose of the steam is to keep the product from drying out during sterilization. Steam cannot be combined any other sterilization technique. е.1. Given the following common laboratory materials, which of the three methods of heat sterilization do you think is the most appropriate and practical to use in sterilizing them Why do you think so ? Method of heat sterilization Reason a. Empty flasks b. L-rod (glass rod) c. 10 ml glass pipet d. Wire needles e. Antibiotic solution5. The ozone layer protects the Earth from nearly 90% of the sun’s ultraviolet rays. In the 1970s, scientists discovered a hole in the ozone layer above Antarctica and since that time, the hole has got much worse. Exposure to ultraviolet rays has serious consequences for our health, but there are ways that we can help solve this problem.
