What's the difference between dominant and recessive traits?
Dominant always shows up if present; is represented by an uppercase letter.
Recessive traits only show up if 2 are present; represented by a lowercase letter.

Name & describe the 3 solutions.
1. Isotonic: Water moves equally in & out
2. Hypertonic; solute sucks water out, cell shrinks
3. Hypotonic; solute sucks water in, cell swells
