I need a model answer for both questions, quoted from A level Biology Oct/Nov 2008 Paper 4
10 (a) Describe the structure of a motor neurone [7]
(b) Explain how an action potential is transmitted along a motor neurone [8]
11 (a) Explain the role of isolating mechanisms in the evolution of new species [8]
(b) Describe and explain, using an example, the process of artificial selection [7]
Thank you.
