Final answer:
The mismatched pair is B. plasma—repairs tissue, as plasma primarily transports substances in the blood but does not directly repair tissue.
Step-by-step explanation:
The correct match that is NOT accurately matched among the options provided is B. plasma—repairs tissue. In the human body, plasma serves primarily as the liquid component of blood that carries cells and proteins throughout the body. It is important for the transportation of nutrients, gases, and wastes and contains proteins that are essential for clotting and immune system functions, but it is not directly responsible for tissue repair. On the other hand, platelets—also known as thrombocytes—are the cell fragments that play a crucial role in blood clotting and, thus, help control bleeding. Red blood cells—or erythrocytes—are primarily tasked with transporting oxygen throughout the body thanks to the hemoglobin they contain. Lastly, leukocytes or white blood cells, are a critical part of the immune response, working to protect the body from invasion by pathogens and foreign substances.
