<span>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.</span>
The climate is changing very quickly and comparison in todays time back then it was changing very slowly thats what i know about that
hope it helps you out good luck
<span>Controlled variable is a variable that was made constant in the research. That was because the controlled variables can influence the dependent or independent variable. If the variables is not made constant, it can alter the research result and made it invalid.
In this case, </span>the caffeine and alcohol intake might alter the physical activity or the blood glucose so it should be controlled.

This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; and worms. The majority of animal species are invertebrates; one estimate puts the figure at 97%.
