Lol can someone explain why the number of Joe Biden related pictures and memes has increased by about 8000 % over the past month or two ? <| sep |> Because although acid is necessary for the reactions to take place efficiently , food digestion is actually driven by enzymes , catalysts that facilitate specific reactions and not others . Digestive enzymes facilitate the breakdown of proteins to amino acids and complex carbohydrates to sugars , but they do not facilitate the further breakdown of those building blocks . Breaking down the building blocks requires very different reactions than breaking apart the large molecules , and would require very different enzymes to happen . <| sep |> On top of those , my Sociology professor stated two characteristics that every good study must have . It must be valid , meaning the data gathered and analyzed is applicable to the abstract or whatever parts dictate exactly what the study is about and how that data will be measured . It must also be reliable , which means the experiments in the study can be recreated exactly and will produce the same results leading to the same conclusion . Without these , a study is garbage .
