Free BCAAâs are a little different in that they are. directly transported to the bloodstream through the. liver, while some exchange in the intestinal viscera and. go directly to the bloodstream also. Most all amino. acids can be degradated, broken down, in the liver. effectively, with the exception of BCAAâs.
They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point, hundreds of millions of years before dinosaurs roamed the earth. Without microbes, we couldnât eat or breathe. Without us, theyâd probably be just fine.
The second microbe that is among the smallest would be bacteria and then probably protists, as a generalization, after that (protists and bacteria have wider ranges of sizes than viruses).Bacteria are microscopic living organisms, while the viruses are non-living sub-microscopic organisms. microbe is an organism that can be seen using a microscope. They  include fungi, bacteria, viruses, archea and protists. All except  fungi consist of a single cell, althou â¦ gh microbe diversity is vast.  Microbes are the causes of many diseases, such as the common cold,  the black death and malaria.
