Scottish Highers Human Biology Division and Differentiation in Human Cells: The diagram shows some stages in

Question

The diagram shows some stages in the development of blood cells.

(a) Name process X.

(b) Name the tissue type to which blood cells belong.

(c) Explain why red blood cells contain haemoglobin after differentiation but white blood cells do not.

(d) Describe how a tumour might develop from cell P.

(e) Cancer patients can be treated using chemotherapy.
This treatment destroys tumour cells but also reduces the number of white blood cells. As a result, patients have a higher chance of infection.
The graph shows the white blood cell count of a cancer patient and their chance of infection in the days following chemotherapy treatment.

(i) State the chance of infection after treatment when the white blood cell count was 0.7 x 10^7/L.

(ii) Predict the white blood cell count seven days following chemotherapy treatment.
