# Modelling biological systems
## MicroSim spec
- **Recommended sim type:** agent-based
- **Microsimmability score:** 74/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Reaction rate`
- `Diffusion rate`
- `Initial concentration`
### What animates
Concentrations in a model cell rise, fall, and spread as the reaction rates change.
### Learning objective
Show how coupled rates model a [[Biological_system|biological system]]'s dynamics.

## Concept summary
Modelling biological systems is a significant task of [[Systems_biology|systems biology]] and mathematical biology.[a] Computational systems biology[b] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems. It ...
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to systems thinking)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Modelling biological systems
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render agent-based; respond live.
}
```
