Answer:
A. contains the cell's DNA
Explanation:
Prokaryotic cells such as the bacterial cells and the cells of archaeans do not have a membrane-bound nucleus. Their genetic material DNA is present in the cytoplasm only. However, their genetic material is concentrated in a specific region inside their cells. This is called a nucleoid. Nucleoid does not have any surrounding membrane. It represents the nuclear area where the DNA of the prokaryotic cells is present.
Paleontologists can identify organisms that may be ancient relatives of those living today. By looking at fossils they can also suggest how these organisms lived together in an ancient habitat. Few organisms become fossilized because the circumstances that an organism has to be in is very specific.

Explanation:
Answer:
The diagram can be improved by:
Lungs
↓
oxygen
↓
Red blood cells (carrying oxygen)
↓
Organs (like stomach and liver etc) from where carbon
is taken and oxygen is supplied
↓
RBC's carrying Carbon dioxide to the lungs
The component which is missing in the diagram are the organs where exchange of gases occurs. The red blood cells carry oxygenated blood from the lungs to all parts of the body and carries the wast carbon dioxide gas from them back to the lungs. The carbon dioxide is then exhaled by the lungs.
