CSEC Biology · January 2013 · Paper 2 · Question 1(a)(i)

An athlete, normally living and training at sea level with a red blood cell count of 4.2 million per unit of blood, began training at 2,500 m above sea level for an event. His red blood cell count was measured monthly for six months. Table 1 shows these counts.

On the grid provided below, draw a graph to represent the data in Table 1.

This question uses a figure or table from the paper — you'll see it when you practise.
