Answer 1

Red blood cells are specialized cells that carry oxygen in multicellular organisms.

Step-by-step explanation:

Red blood cells are specialized cells found in multicellular organisms that are responsible for carrying oxygen throughout the body. They contain a protein called hemoglobin, which binds to oxygen in the lungs and releases it to the body's tissues. Red blood cells are produced in the bone marrow and have a unique disc-like shape that allows them to squeeze through small blood vessels.
