CSEC Biology · May/June 2005 · Paper 2 · Question 1(c)(i)

In another study, students found specimens A to D, shown in Figure 2, and claim they belong to the same group.

Identify TWO features shown in the drawings that can be used to classify the specimens.

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

The mark scheme is shown once you've answered.
