Answer: A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1).
Explanation:
B. By lowering the energy need for the reaction, you increase the reaction speed or the rate.
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.
