Selective breeding and genetic engineering practice
Mastery score
Make it concrete
Analogy
Selective breeding and genetic engineering is like a living system solving a small survival problem: each part has a job, and the answer depends on how those jobs connect.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Why it matters
Real-world use
Selective breeding and genetic engineering helps explain health, ecosystems, medicine and how organisms stay alive. Example: For a longer answer, name the key biological part and explain how it helps the organism or system work.
Why now: Real examples make the mark-scheme words easier to remember.
Do this: Connect one key word to the example.
