Salty meal --> digestive process --> hypertonic blood plasma --> hypertonic intestinal fluid --> pulls H2O from cells --> increase in blood plasma volume --> increase in blood pressure and increase in thirst --> increase of urine in the kidneys.
Dinosaurs lived between 230 and 65 million years ago, in a time known as the Mesozoic Era. This was many millions of years before the first modern humans, Homo sapiens, appeared. Scientists divide the Mesozoic Era into three periods: the Triassic, Jurassic and Cretaceous. During this time, the land gradually split up from one huge continent into smaller ones. The associated changes in the climate and vegetation affected how dinosaurs evolved.
ERA OF THE DINOSAURS. Dinosaurs roamed the planet for about 165 million years, during a time in the Earthâs history called the Mesozoic Era. It is difficult to imagine how long this was, until we compare it with ourselves: humans have lived on Earth for less than two million years.
