Then, matter and light that exist today hadn't appeared yet. All particles that formed the atoms of the Universe have passed a process of transformation: The proofs of this theory are cosmic background radiation and the fact that the hydrogen/helium ratio that exists in the Universe is practically the same as that calculated by the model]]> 2023-03-02 00:59:25 UTC https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2500351609 4 fundamental forces that exist in nature b31410 https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692735165 Gravity, strong nuclear forces, weak nuclear forces and electromagnetism, were probably united or undifferentiated before the Big Bang, due to the conditions of enormous density andtemperature.]]> 2023-09-11 02:33:46 UTC https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692735165 Cosmic plasma b31410 https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692739909 Before reaching the limit of 380 thousand years, the Universe was kind of heated cosmic plasma, conformed exclusively of elemental particles of matter and antimatter]]> 2023-09-11 02:37:26 UTC https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692739909 Helium b31410 https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692744780 The electric attraction between photons and electrons allowed for the formation of the interactions of the strong nuclear forces

    After these metabolic processes in primitive organisms, RNA gave way to DNA, which facilitated genome preservation and transmission since the double elise structure of DNA had greater stability compared to RNA, all this resulting in a considerable reduction in Generic damage and mutations that used to occur,]]>     2023-09-11 03:28:57 UTC https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692894137     Ecukarite lineage of the kingdom animalia and the kingdom fungi b31410 https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692981190 The separation occurs in the ecukarite lineage of the kingdom animalia and the kingdom fungi]]> 2023-09-11 03:31:27 UTC https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2692981190 1735 Classification taxonomic categories b31410 https://padlet.com/b31410/ab289y4gxlpgwgfm/wish/2693030369 Linnaeus was the one who set the rules in his book Systema Naturae (1735); he
    determined that species would be ordered  heriarchical or classification
    taxonomic categories    ; these categories , in decreasing direction, were:
    • Kingdom
    • Phylum
    • Class
    • Order
    • Family
    • Gender
    • Species
    To name all species, Linnaeus created a code of binomial nomenclature, a set of
    rules to designate binary names to species:
    • The first name: genus category.
    • Second name: species category
