I'm pretty sure the answer is B
Gas is the correct answer
Answer:
The bacteria were growing through fermentation process.
Explanation:
Cyanide have the ability to prevent the growth of microbes, and that is why it usually added to paints that want to be applied to places where the growth of microbes will be harmful to people.
The ships' hull where ballast water is been stored needed to be painted with cyanide to prevent the growth of microbes.
It should be noted that, anaerobic microbes have the ability to reduce cyanide compound through a process known as submerged fermentation.
In the case of ships' hull, the bacteria growing on the hull were anaerobic, which means, they carried out their activities in the absence of oxygen.
Veins provide support for the leaf and transport both water and minerals (via xylem) and food energy (via phloem) through the leaf and on to the rest of the plant.
