### Non-biology concepts:
- ratio
- equals, times, plus, divides, fraction
- chemical equations (varied!)
- power
- percent
- range: pH 1-2 , heart rate 60-80
- number (notation #2 for "number 2")
- pH (power-of-hydrogen,acidity,basicity)
- concentration - [H^+]
- note double-positive ions - Fe^{++} and Fe^{⊕⊕}
  see https://en.wikipedia.org/wiki/Ion

### Biology concepts:
- codon - example CAG, CGA, UUG
- dna-sequence - example CAGTATACG
- :amino-acid - notation leu, arg, his (leucine, arginine, histidine)
- auxotrophic/not-auxotrophic - notation leu^{-} arg^{+}
- dna-strand - example `5'-CTTA` but also `AATTC-3'` - dash is silent, prime is spoken.

- blood-pressure - 120/80 spoken "120 over 80"
- genotype - I^A - spoken concatenated "cap I cap A"
