The DNA molecule is a double helix, shaped like a twisted ladder.
If I would have to make a good guess, I would choose A.
Answer;
It is a saccharolytic organism that can utilize carbohydrates anaerobically, therefore there is no evolution of co2.
Explanation;
A saccharolytic bacterium is a microbe having the ability to generate energy by metabolizing carbohydrates.
They include both heterotrophic and autotrophic organisms and transform sugars under aerobic and anaerobic conditions.
The energy-generating metabolic processes for obligate anaerobes are not coupled with the consumption of oxygen, oxygen kills the organisms.
<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>
B, hormones that serve as chemical messengers im not 100% sure though
