Week's topic



    Wednesday we learned about all the theories that try to explain the origins of life. There is the creationist theory that explains the origin of life from a religious  point of view. Panspermia theory proposes that life traveled to earth by a meteorite. Big bang tells about a big explosion that created life. Physical - Chemical theory takes a scientific perspective. There's also exist a new theory, Endosymbiont theory that said that first the atmosphere was anaerobic. We also learned about the Oparin and Haldane's hypothesis.
    On friday  we saw the different characteristics of living  things about unicellular and pluricellular organisms. About the adaptation to the environment and the homeostasis.
