What features of ionizing radiation make it a good choice for killing microbes in packaged materials? A. ionizing radiation is able to penetrate the packaging materials

B. ionizing radiation is safe for killing microbes on living surfaces (such as human tissues)

C. ionizing radiation kills endospores

D. ionizing radiation does not require special instruments or equipment

Normally sterilizing food using radiation does not induce radioactivity but sometimes it may change the taste, texture of the food and it may also destroy the nutrients. radiation is used to kill the harmful bacteria and to increase the shelf life. when the radiation is very energetic it alters the food structure but it does not make it radioactive. To become radioactive one has to make a nucleus unstable. ionizing radiation normally cannot do this. FDA has established maximum energy levels for radiation to prevent the treated foods from becoming radioactive. The energy levels of the rays are too low to induce radioactivity in the food. So there is no harm in consuming treated foods.

Explanation:

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.

helicase, i think thats it
