Enzymes: Are proteins that function as biological catalysts so they are molecules that speed up chemical reaction without beeing changed by the reaction.
Biomolecules: Carbohydrates, proteins, lipids(organic). Water (inorganic, not carbon). Substance that our body needs to survive and have energy, helps damage tissues, growth and inunity.
Difussion: The speading or movement of particles from an area of high concentration to a low concentration. E.G: gas exchange alveoli humans, and photosynthesis gas exhange in stomata and in liver cells movement of particles in the bili by absortion of nutrients.
Osmosis: the movement of water particles (like difusion but only liquids) sugar in partially permeable membrane.
Sexual and asexual reproduction: Sexual involves fusion of gametes, sperm and egg, between animals 2 parents variation offspring. Asexual doesnt need gametes and is bacteria fungui... And is a copy in offspring, dividing in two.
Biodiversity: Is the human activity impact on the enviroment like: destruction of natural habitats, over hunting, climate change, polution, global warming, waste managment. And the carbon cycle is the movement of carbon in the enviroment and atmosphere.
