Jimson weed Nightshade hallucinogen, opens at night; native to India or Central America.
Epicanthic fold weaker eyelid muscles
Facets: surfaces of ommatidia: each with lens & nerve fibres = mosaic image. The N/Y is a lethal male; mistake in locating the N alleles for the lower 2 cases? No

  1. allo - other; amphi - both
  2. Epiglottis: flap between trachea and esophagus
  3. Glottis: space between vocal cords in the larynx
  4. Larynx: voicebox (Adam's apple is part of it)
  5. Jimson weed Datura stramonium: native to tropical America; variable toxic alkaloids; narcotic "trip"!
  6. Cotton boll: fiber (hair) in pod (fruit) of cellulose for seed dispersed: long "lint", short "fuzz"
    Gossypium hirsutum (Malvaceae) cultivated 7,000 years ago; similar to pappus os Compositae
  7. polytene chromosome: replication without cell division; chromatids remain together in interphase for LM; sponging/sucking mouthpart.
  8. para: beside, near, apart; peri: around or about
  9. inversions effects: position effect
