How do biologists explain living systems?
Biology connects structure, function, energy and change across generations.
Background and goal
No prior study required. Read the assigned passage; the route is an introduction, not a survey of the whole subject.
Draw one cell’s inputs, processes and outputs, then identify what your diagram leaves unexplained.

Answer this question in your own words: How do biologists explain living systems?
Hint
Name the claim, then explain why a reader might accept it.
Compare with an example answer
Biology connects structure, function, energy and change across generations.
What to look for
- States a claim that addresses the question
- Connects the claim to a passage or observation
- Separates the author’s argument from personal agreement
Common mistake: Summarising a biography instead of explaining the argument.

What would make your activity a convincing example?
Hint
Draw one cell’s inputs, processes and outputs, then identify what your diagram leaves unexplained.
Compare with an example answer
A useful response carries out the task: Draw one cell’s inputs, processes and outputs, then identify what your diagram leaves unexplained. It records the observation or passage used and explains how it bears on the question.
What to look for
- Completes the specific task
- Shows evidence or reasoning rather than only a conclusion
- Identifies an alternative explanation or reading
Common mistake: Presenting an opinion without showing the example it rests on.

Try thisRevise your initial answer. Include one passage, one reason and one limit: A functional description does not by itself explain how a trait evolved.Your outputRevised answer with a reading referenceCheck your understanding
What is one conclusion this reading does not establish?
Hint
Test the boundary: A functional description does not by itself explain how a trait evolved.
Compare with an example answer
A functional description does not by itself explain how a trait evolved.
What to look for
- States a specific limit
- Explains why the reading does not warrant the stronger conclusion
- Distinguishes a limitation from dismissing the work
Common mistake: Treating a useful interpretation as an unrestricted fact.
