The correct comparison between an amoeba and a red blood cell is: "An amoeba is responsible for all functions, and a red blood cell is responsible for some functions."
Here's a brief explanation:
- An amoeba is a single-celled organism that can perform all necessary life functions such as movement, feeding, and reproduction.
- A red blood cell, on the other hand, is a specialized cell in multicellular organisms primarily responsible for transporting oxygen, but it does not carry out all life functions on its own.
