Document Summary

Duplet organizations = 2 microtubules / 1 dyenin arm (total 9 duplets) spiral / propeller movement. Haploid (gamete producing) phase followed by diploid (self preservation) phase: asexual reproduction = mitosis = no variation, sexual reproduction = meiosis = variation! Actin + myosin + atp interact strongly = ectoplasm (solid) Ectoplasm (liquid) hits hyaline cap, deflects back along sides, solidifies at end. Y shaped at ends, each only fits into a specific germ. Stimulates production of antibodies + combine specifically with them to neutralize themselves! 1 / 3 phylogenetic tree of prokaryotes unicellular, lack nuclei: can live in extremely high / low temperatures, some live in salty, acidic, alkaline water, some found in geysers, black smokers, oil wells. No variation offspring / parents = identical. No gestation period, new generation created instantly w/ mitosis of parent. Types: binary fission (bacteria, budding (plants, spores (fungi) If attack human body, use its nutrients as source of energy parasitic.
