Marine biology is the scientific study of marine life, organisms in the sea.Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this large proportion is unknown.

Order Of Quantum Mechanics Thus many quantum-gravity theorists believe there is a deeper level of reality, where space does not exist. These days, many of us working on quantum gravity believe that causality itself is fundamental– and is thus meaningful even at a level where the notion of space has disappeared. Lee Smolin, The Trouble with Physics, The Rise of String Theory, the Fall of a Science, and What Comes. Oct 22, 2018. Our analysis supports a top–down structure in quantum mechanics according to which higher-order correlations can always determine. In quantum mechanics, perturbation theory is a set of approximation schemes directly related to

Influenza was discovered not by a direct study of the disease in humans, but rather from studies on animal diseases. In 1918, J.S. Koen, a veterinarian, observed a disease in pigs which was believed to be the same disease as the now famous “Spanish” influenza pandemic of 1918.
