Step 2
Suggest why not having a nucleus in a red blood cell is an advantage.

Not having a nucleus allows red blood cells to have more space for hemoglobin, the protein that carries oxygen. This increases their efficiency in transporting oxygen throughout the body. Additionally, it allows the red blood cells to be more flexible, enabling them to pass through narrow capillaries more easily.
