ORACIÓN DE MAIMONIDES

In physics, an orbit is the gravitationally curved path of an object around a point in space, for example the orbit of a planet around the center of a star system, such as the Solar System.[1][2] Orbits of planets are typically elliptical. Asteroids  are a class of small Solar System bodies in orbit around the Sun. A comet is an icy small Solar System body (SSSB) that, when close enough tothe Sun, displays a visible coma (a thin, fuzzy, temporaryatmosphere) and sometimes also a tail. A star is a massive, luminous sphere of plasma held together by gravity. In modern astronomy, a constellation is an internationally defined area of the celestial sphere. As seen from the Earth, a Solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks theSun. A lunar eclipse occurs when the Moon passes behind the Earth so that the Earth blocks the Sun's rays from striking the Moon.  A galaxy is a massive, gravitationally bound system that consists of stars and stellar remnants, an interstellar medium of gas and dust, and an important but poorly understood component tentatively dubbed dark matter. A telescope is an instrument that aids in theobservation of remote objects by collecting electromagnetic radiation (such as visible light). An Astronaut or Cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. A spacecraft or spaceship is a vehicle, vessel or machine designed for spaceflight.  A rocket is a missile, spacecraft, aircraft or other vehicle that obtains thrust froma rocket engine. A space probe is a scientific space exploration mission in which a spacecraft leaves Earth and explores space. The Apollo Lunar Module (LM), also known as the Lunar Excursion Module (LEM), was the lander portion of the Apollo spacecraft built for the US Apollo program by Grumman to carry a crew of two from lunar orbit to the surface and back. Six such craft successfully landed onthe Moon between 1969–1972. An unidentified flying object, often abbreviated UFO or U.F.O., is an unusual apparent anomaly in the sky that is not readily identifiable to the observer as any known object, often associated with extraterrestrial life. Research and experimental development is creative work undertaken systematically to increase the stock of knowledge, including knowledge of humanity,culture and society, and the use of this stock of knowledge to devise new applications. A satellite is an object which has been placed into orbit by human endeavour. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. Serve: to be in the service of; work for. Shuttle: A relatively small spacecraft, usually capableof atmospheric transport. spacecraft : A vehicle that travels through space. TEST: a particular process or method for trying or assessing. Traverse: To travel across, often under difficult conditions. TRIP: a journey or voyage. Unmanned: without the physical presence of people in control.

Del griego exo, fuera, y osmōs, acción de empujar). Nombre aplicado a la corriente osmótica que, a través de una membranasemipermeable, sale de un sistema cerrado (por ejemplo una célula) cuyo contenido es hipotónico con relación al medio ambiente. Conceptos relacionados:endósmosis y osmótica (presión). (Del griego endon, por dentro y osmós, acción de empujar). Nombre aplicado a la corriente osmótica que, a través de una membrana semipermeable, penetra en un sistema cerrado (por ejemplo una célula) cuyo contenidoes hipertónico en relación al medio ambiente. Conceptos relacionados: exósmosis y osmótica (presión).Los exones son las regiones de un gen que no son separadas durante el proceso de splicing y, por tanto, se mantienen en el ARN mensajero maduro. En los genes que codifican una proteína, son los exones los que contienen la información para producir la proteínacodificada en el gen. En estos casos,...
