Free response questions
Free response questions will appear throughout both exam papers (Breadth and Depth), and at both Foundation Tier and Higher Tier.
These questions provide answer lines for you to write your answer, and may sometimes also provide a blank space for you to draw a diagram or show your working out.
The number of answer lines and the number of marks for the question are guides to the amount of detail to include in your answer. A question worth 1 mark with only one answer line probably only requires a one-sentence answer, or perhaps just a single word or phrase. For questions with more marks and more answer lines you will have to go into more detail or give specific data points, eg:
- the number of deaths from cardiovascular disease increased [1 mark]
- the number of deaths from cardiovascular disease increased by 50% [2 marks]
Free response questions often start with a command word such as 'describe' or 'explain'. It's important to understand the different types of answers required by 'describe' and 'explain'. As a rule of thumb:
- describe what happens, when and where
- explain how and why it happens ("it happens because…")
Other command words you might see include:
- 'write down' (give a short answer, without explaining it)
- 'suggest' (use your scientific knowledge and understanding to give a sensible answer in an unfamiliar context)
- 'compare' (write about the similarities and differences between two things)
- 'discuss' (write about the issues related to a topic, and talk about arguments for and against).
Sample question 1 - Foundation
Question
Humans are able to control their internal temperature.
Describe how the skin looks when the temperature drops. [2 marks]
OCR 21st Century, GCE Biology, Paper J257, 2016.
Goes pale OR vasoconstriction [1 mark]
Hairs stand up [1 mark]
Sample question 2 - Foundation
Question
In a reflex arc the components of the nervous system work together. The order of these components is important.
The sequence is described below but the events are in the wrong order.
Place them in the correct order. Statement 1 is in the correct place. [2 marks]
- A receptor detects a stimulus.
- A motor neuron sends an impulse to an effector.
- An effector produces a response.
- A sensory neuron sends an impulse to a relay neuron.
OCR 21st Century, GCE Biology, Paper J257, 2016.
- A receptor detects a stimulus.
- A sensory neuron sends an impulse to a relay neuron.
- A motor neuron sends an impulse to an effector.
- An effector produces a response.
Sample question 3 - Foundation
Question
Some students could see a Daphnia's heart beating. In humans the heart forms part of the circulatory system.
What role does the heart play in these systems?[1 mark]
OCR 21st Century, GCE Biology, Paper J257, 2016.
It acts as a pump.
Sample question 4 - Higher
Question
What is the role of red blood cells? [1 mark]
OCR 21st Century, GCE Biology, Paper J257, 2016.
To transport oxygen.
Sample question 5 - Higher
Question
A doctor checks to see if Sarah has an underactive thyroid gland because this could make her feel tired.
The thyroid gland produces a hormone.
What is the role of hormones?
OCR 21st Century, GCE Biology, Paper J257, 2016.
They are chemical messengers.
Sample question 6 - Higher
Question
Insulin is a hormone produced by the pancreas.
The graph below shows data from two people who were given a sugary drink.
Their blood sugar level was recorded every 60 minutes from when they had the drink.
There are two types of diabetes - Type 1 and Type 2.
Person A has Type 2 diabetes. Person B does not have diabetes.
Describe how the graph shows this and explain why there is a difference in the blood sugar level. [2 marks]
OCR 21st Century, GCE Biology, Paper J257, 2016.
One mark will be given for one of these four points:
- Person B's glucose level falls faster than person A's
- Person A's glucose level falls more slowly than person B's
- Person B's glucose level falls back to starting level after just over 2 hours
- Person A's glucose level remains high
The second mark will be given for one of these explanations:
- Person A does not respond to the insulin produced to convert glucose to glycogen
- Person B produces insulin in response to the rise in blood glucose and this causes cells to convert the glucose to glycogen so the blood glucose level falls
