Q&A to prepare for Question 7 of Edexcel Biology Paper 3: General and Practical Applications in Biology (BN0/03).
After successfully preempting the actual live questions of 9BN0/03 in 2016 and 2017 (in 2017, Q7parts a-h were predicted totalling 22 of the 30 marks available) I have again created a set of resources that will prepare any student for the pre-release section of paper 3.
This year I have written a total of 119 questions with answers (worth a total of 315 marks). These have been split into the following three documents:
1- A set of 89 questions and answers (225 marks) which may be used in class as as homework
2- Mock paper 1 comprised of 16 questions and answers (worth 45 marks)
3- Mock paper 2 comprised of 14 questions and answers (worth 45 marks)
Of course, feel free to use them in any way you prefer.
I include a snapshot of 8 questions below:
Q8. “Retraining the brain” is a form of learning. Define what is meant by ‘learning’. 
Q9. How does your natural gut flora protect your body from infection? 
Q10. The relationship between gut flora and host is said to be mutualistic. What does this mean? 
Q11. Define what a fat is and describe the structure of one example. 
Q12. Describe the structure of a sugar. 
Q13. Describe the structure of an amino acid. 
Q14. State the formula for calculating BMI. 
Q15. What is meant by “the dopamine pathway”?
