Question 1 of 3 · No calculator needed
An atom has atomic number 8 and mass number 18. How many neutrons does it contain?
Atomic number gives 8 protons, while mass number is protons plus neutrons. Neutrons = 18 - 8 = 10.

Question 2 of 3 · No calculator needed
At high light intensity, increasing light no longer raises photosynthesis, but adding carbon dioxide does. What is limiting the rate?
The rate responds to added carbon dioxide but not extra light, showing carbon dioxide is limiting under these conditions. The limiting factor is the one in shortest effective supply.
Question 3 of 3 · No calculator needed
Why are FSH and LH used during IVF treatment?
FSH stimulates several eggs to mature and LH triggers their release for collection. Eggs can then be fertilised in a laboratory before embryos are transferred.
These tiles show your answers to three questions. They are a starting point, not a mastery score or grade prediction.
Building blocks
Correct answer: 10
Atomic number gives 8 protons, while mass number is protons plus neutrons. Neutrons = 18 - 8 = 10.
Transport over larger distances
Correct answer: Carbon dioxide concentration
The rate responds to added carbon dioxide but not extra light, showing carbon dioxide is limiting under these conditions. The limiting factor is the one in shortest effective supply.
Interactions with the environment
Correct answer: FSH matures eggs and LH stimulates their release
FSH stimulates several eggs to mature and LH triggers their release for collection. Eggs can then be fertilised in a laboratory before embryos are transferred.
For parents: look at the explanation together. A correct answer is encouraging; a missed answer gives you something specific to work on. Broader practice over time is needed to understand progress.

01Building blocks
Specification reference: 4.1
During melting, transferred energy increases the potential energy of particles by overcoming attractions. Average kinetic energy and therefore temperature remain constant until the change is complete.
Watch for: Do not repeat the wording of Building blocks. Explain the underlying rule or relationship, apply it to the context and check the command word.
02Transport over larger distances
Specification reference: 4.2
Endocrine glands release hormones directly into the blood, which carries them to target organs with matching receptors. Hormonal responses are often slower and longer-lasting than nervous ones.
Watch for: Do not repeat the wording of Transport over larger distances. Explain the underlying rule or relationship, apply it to the context and check the command word.
03Interactions with the environment
Specification reference: 4.3
Contamination means unwanted radioactive material is present on or inside something and may keep exposing it. Irradiation exposes an object to radiation without transferring the source.
Watch for: Do not repeat the wording of Interactions with the environment. Explain the underlying rule or relationship, apply it to the context and check the command word.
04Explaining change
Specification reference: 4.4
Separating dissolved ions requires energy for boiling and condensation or for forcing water through membranes. Fresh-water treatment generally needs filtration and sterilisation only.
Watch for: Do not repeat the wording of Explaining change. Explain the underlying rule or relationship, apply it to the context and check the command word.
05Building blocks for understanding
Specification reference: 4.5
Noble-gas atoms already have stable outer electron configurations, so they have little tendency to gain, lose or share electrons. Their boiling points increase down the group.
Watch for: Do not repeat the wording of Building blocks for understanding. Explain the underlying rule or relationship, apply it to the context and check the command word.
06Interactions over small and large distances
Specification reference: 4.6
Reversing either current direction or magnetic field reverses the motor-effect forces on the coil. Reversing both together leaves the rotation direction unchanged.
Watch for: Do not repeat the wording of Interactions over small and large distances. Explain the underlying rule or relationship, apply it to the context and check the command word.
07Movement and interactions
Specification reference: 4.7
A catalyst lowers the activation energy by providing an alternative pathway. A greater fraction of collisions are therefore successful, while the catalyst remains chemically unchanged overall.
Watch for: Do not repeat the wording of Movement and interactions. Explain the underlying rule or relationship, apply it to the context and check the command word.
08Guiding Spaceship Earth towards a sustainable future
Specification reference: 4.8
Life-cycle assessments depend on system boundaries, data quality and judgments about how different impacts are weighted. Transparent assumptions are essential when comparing conclusions.
Watch for: Do not repeat the wording of Guiding Spaceship Earth towards a sustainable future. Explain the underlying rule or relationship, apply it to the context and check the command word.

AQA · GCSE · Combined Science: Synergy · 8465
Version 1.1, 30 September 2019; current specification checked 27 August 2026
Source checked: 2026-08-27. The current official specification controls assessment requirements and option choices.
Can parents and students try LearningP before signing up?
Yes. This page offers three original questions from three different skills on this exact course. Each answer has an explanation, followed by a sample heatmap showing what was correct and what to revisit. No account is needed, and taster answers are not saved.
What does the three-question heatmap tell a parent?
It shows the outcome of these three answers and gives a specific skill to discuss or practise next. It is not a full assessment, a mastery score or a grade prediction. Broader practice over time is needed to understand progress.
What does the AQA GCSE Combined Science: Synergy route cover?
LearningP currently maps 8 assessed areas for specification 8465. The visible topic map below is derived from the verified route; the current official specification remains controlling.
How many LearningP questions support this route?
The verified source bank contains 80 original LearningP question records for this route. Every mapped area meets the current publication minimum and passed the latest blocker and review audit.
Does LearningP reproduce official exam questions?
No. LearningP uses official specifications and assessment materials to map content and demand, while its practice questions and explanations are independently authored.
Can this page predict an exam grade?
No. LearningP reports practice evidence, coverage, strengths and gaps. It does not guarantee or automatically predict examination outcomes.
Where should current assessment information be checked?
Use the official AQA specification and assessment-resource pages linked on this page, together with information supplied by the learner’s school.
