Bird skeletons are very delicate, and therefore, difficult to be preserved. The bones of the birds are soft. The small animals are very prone to physicochemical as well as biological decay. This is why the fossil record of bird is incomplete and well-preserved fossils of birds are rare to find, except at a few unusual sites.
Cellular respiration is a cellular process in the metabolism of sugar components to produce metabolites such as lactic acid, acetic acid, aldehydes, and other components. It starts with the cleaving of the sugar component (6-carbon) to 3-carbon components until it becomes pyruvate
<span>The first carbon dioxide is produced in between glycolysis and the Krebs/citric acid cycle. </span>
