The correct statement regarding the differences between red blood cells and neurons is:
**b. neurons contain DNA but red blood cells do not.**
**Explanation:**
- **Neurons** are specialized cells in the nervous system that do contain DNA within their nuclei, allowing them to carry out complex functions such as generating and transmitting electrical signals.
- **Red blood cells (erythrocytes)**, on the other hand, do not have a nucleus or DNA. They lose their nucleus during maturation, which allows for more hemoglobin to be packed into the cell for efficient oxygen transport.
The other statements are not correct:
- **a.** Neurons do contain organelles, while mature red blood cells lack many organelles due to their unique function.
- **c.** Neurons do need oxygen for their metabolic processes, but red blood cells do not need oxygen as they primarily function to transport it.
- **d.** Both neurons and red blood cells can vary in size, and this statement is not accurate.
