Coral Reefs are the underwater ecosystem whilst <span>Symbiosis is just what the concept entails. </span>
Answer:
idk if this is what you're asking for, but water molecules are polar, so they form hydrogen bonds. This gives water properties such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
The correct answer is B - nucleoid.
The nucleoid is a region in a prokaryotic cell that houses the main DNA material of the cell.
In contrast to eukaryotic cells with a nucleus, prokaryote have a nucleoid where the genetic material can be found. The nucleoid is different from the nucleus in eukaryotes in that the genetic material is not enclosed in a membrane to separate it from the cytoplasm.
The nucleoid usually contains only a single chromosome which has the cell DNA.
