Bio help

[dannybobanny182]

Anyone have funny or easy way to understand/memorize the following?
1) Bio diversity
2) Plant
3) Hypertonic vs Hypotonic
4) Embryonic to Extraembryonic development (any flow charts?)
5) Autosomal vs X-linked dominant (dominant/recessive)

Thanks!

3) i memorize as hypo being a word like hydro (water) so it has more solvent(water for example) and less solute.
since theres more solvent/water, it'll always flow out to the hypertonic environment since hypertonic has less solvent.
