You will be expected to write in more depth for three and four mark questions. They might ask you about a process such as digestion or ventilation or compare differences, such as with blood vessels.
Remember to try to answer in complete sentences.
These questions have been written by Bitesize consultants as suggestions to the types of questions that may appear in an exam paper.

In an exam, you would not be penalised if the method you described was slightly different - for instance, if you had suggested using 2 cm3 of Benedict's solution instead of 1 cm3.
However, do try to specify a level of detail in your answer rather than be vague, for instance about the volume of Benedict's solution used.
