Life arose from the Earth's first ocean, which formed some 3.8 billion years ago. [33] Since then, water continues to be the most abundant molecule in every organism. Water is important to life because it is an effective solvent , capable of dissolving solutes such as sodium and chloride ions or other small molecules to form an aqueous solution .
The process of breathing does not fill the alveoli with atmospheric air during each inhalation (about 350 ml per breath), but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas (about 2.5 liters in adult humans) known as the functional residual capacity which remains in the lungs after each exhalation, and ...
The snowy owl was included in the 10th edition as Strix scandiaca. Linnaeus described birds as: "A beautiful and cheerful portion of created nature consisting of animals having a body covered with feathers and down; protracted and naked jaws (the beak), two wings formed for flight, and two feet. They are areal, vocal, swift and light, and ...
According to Dickinson's hypothesis, the chief obstacle to admitting the past existence of dragons is the difficulty of powered flight by such a large organism. To resolve this, he introduces a dirigible-like structure in which hydrochloric acid would dissolve large amounts of rapidly growing bone, releasing massive amounts of hydrogen that, once aloft, would support the body above the ground.
Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
English inventions and discoveries are objects, processes or techniques invented, innovated or discovered, partially or entirely, in England by a person from England. Often, things discovered for the first time are also called inventions and in many cases, there is no clear line between the two. Nonetheless, science and technology in England ...
The word "manuscript" derives from the Latin: manūscriptum (from manus, hand and scriptum from scribere, to write), and is first recorded in English in 1597. [ 3 ] [ 4 ] An earlier term in English that shares the meaning of a handwritten document is "hand-writ" (or "handwrit"), which is first attested around 1175 and is now rarely used. [ 5 ]
