Cross-Topic Connections
📋 What it is
Biology topics link up: cells build bodies, genes shape adaptations, and ecosystems tie species together.
🗣️ Coach says
Nothing in biology stands alone. Cells make up body systems; DNA in those cells drives the traits natural selection shapes; and those adapted species interlock into ecosystems. Understanding one topic makes the next one click — it’s all one connected story of life.
🧠 Memory hook
Cells → bodies → genes → adaptations → ecosystems. One connected story.

What do you call a lazy neuron?
A nerve that won't fire — it just doesn't have the impulse!
😲 Whoa!
The same four DNA “letters” (A, T, C, G) spell out EVERY living thing — a bacterium, an oak tree, and you all run on the same code.
✅ Quick check: How does genetics connect to evolution?
Say your answer out loud first — then reveal.
Genes carry the traits that vary between individuals; evolution acts on that variation, spreading the helpful genes over generations.
Genetics supplies the heritable variation that natural selection works on.
