Question

1. scenario 1 - scientists are attempting to identify the specific type of leukemia a person has based on cell surface structures. 8. scenario 2 - researchers are studying chemotaxis in white blood cells. chemotaxis is the movement of living cells in response to a particular substance.

Explanation:

Scenario 1 involves identifying leukemia type using cell - surface structures which is a biological study related to cancer and cell biology. Scenario 2 focuses on chemotaxis in white blood cells, which is also a biological process related to cell movement. Both scenarios deal with biological concepts.

Answer:

Both scenarios pertain to Biology.
