The crossing over mechanism of genetic variation results from the exchange of gene segments between non sister chromatids. The correct answer is 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.
