Document Summary

Nebular hypothesis: explains how the solar system was created. Interstellar gas and clouds: starts to rotate and spin in a disc, nuclear fusion in the middle where sun is form, accretion of objects on the outside, differentiation. Water can be in many different forms, allow sun to penetrate through (photosynthesis), allows chemicals to go through, the solid form is less dense than the liquid. Three hypothesis that explain lifes origin: heterotrophic hypothesis (cid:894)(cid:858)p(cid:396)i(cid:373)o(cid:396)dial soup(cid:859)(cid:895) Inorganic chemicals in the ocean: pa(cid:374)spe(cid:396)(cid:373)ia hypothesis (cid:894)(cid:862)seeds f(cid:396)o(cid:373) spa(cid:272)e(cid:863)(cid:895, meteorites from space hit earth and had microbes delivered, organic compounds found on meteorites, che(cid:373)oautot(cid:396)ophi(cid:272) hypothesis (cid:894)(cid:862)o(cid:272)ea(cid:374) depths(cid:895, originated in the deep hydrothermal vents of the ocean.

Dynamic equilibrium systems are constantly changing, interacting, balancing. Homeostasis many systems tend to maintain internal conditions (=resistance) Resilience systems tend to come back (recover) easily from disturbances.
