Mantle secretes calcium to make valves Foot makes Byssus threads Gills feeding/breathing Muscles: Snails (gastropods), bivalves (mussels), squids/octopus (cephalopods) Synapomorphies: foot, mantle, visceral mass Hemocytometer: Biggest square: 1mm X 1mm = 1mm^2 Middle square: .2mm X .2mm = .04mm^2 Small square: .05mm X .05mm = .0025mm^2 Blood sugar regulation: High blood sugar release insulin absorbs glucose b.s. down Low blood sugar glucagon released liver creates glucose b.s. up Negative feedback loop Seed Germination Seed imbibes GA released by embryo to aleurone aleurone releases amylase into endosperm amylase breaks down starchy endosperm nutrients taken up by scutellum into the developing embryo ABA: creates proteins that block alpha amylase production Agar Plate Experiment E + starch = clear zone (amylase active/starch breakdown) O + starch = dark zone (starch present) E + starch + GA = clear zone (biggest clear zone) O + starch + GA = clear zone Spectrophotometer Experiment Tube = water + sample + starch + iodine + water Starch: initiated reaction Iodine: stops the reaction and forms blue complex with starch
