Question

Which property do white blood cells have in common?

1) They are colorless
2) They are larger than red blood cells
3) They are involved in the immune response
4) They are found only in the bone marrow

Answer 1

White blood cells are primarily involved in the immune response to pathogens, a trait they all share. The correct option is 3) They are involved in the immune response

Step-by-step explanation:

The property that white blood cells (WBCs) have in common is that they are involved in the immune response. While WBCs are typically larger than red blood cells and do not contain hemoglobin, a defining characteristic is their role in defending the body against infections.

These cells actively engage in identifying and targeting pathogens like bacteria, viruses, and other foreign organisms. Although WBCs are formed in the bone marrow, they are not found only there; they circulate throughout the body and some mature in the lymphatic system.

WBCs do have a nucleus and organelles, which is another difference from red blood cells. The correct option is 3) They are involved in the immune response
