If a meteorite contains no traces of carbon can it be concluded there is life at the meteorite's origin?
No. The best element for building life is carbon. As we know there is no life form that would be able to endure cosmic void and heat produced when a metorite is flying through atmosphere. There is a high probability that a life form (regerdless if carbon or some other element based) in the meteorite would burn without leaving traces on it.
What else can I help you with?
A rock from space that hits the earth is called a?
Space rocks floating through the sky are called meteoroids. When they are passing through the Earth's atmosphere and are heated to incandescence, they are called "meteors". If they crash to Earth, they are called "meteorites". Not all meteors survive to become meteorites. Many meteors burn up completely in the Earth's atmosphere.
What are the three types of asteroids?
A meteoroid which reaches the ground is called a meteorite. A small number of meteorites have been found which scientists believe originated on the Moon or Mars. The composition of meteorites gives us valuable information about the universe. Meteorites typically fall into one of five categories.IronsThese meteorites are made of a crystalline iron-nickel alloy that resembles the outer core of the earth. Similar in structure to some asteroids (type M), 5.7% of meteorites are irons.Stony-IronsThese meteorites are mixtures of iron-nickel alloy and non-metallic mineral matter. Scientists believe they are like the material which would be found where the Earth's core meets the mantle. 1.5% of meteorite falls are stony irons.Stony MeteoritesThere are three subclasses of stony meteorites:Chondrites: These meteorites are the most numerous, comprising 85.7% of all meteorites found. They are characterized by chondrules: small (average diameter of 1 millimeter) spheres of formerly melted minerals that have melded with other minerals to form a solid rock. Chondrites are believed to be among the oldest rocks in the solar system and are similar in composition to the mantles and crusts of earth and the other terrestrial planets.Carbonaceous Chondrites: These meteorites are very rare and contain elemental carbon, the basic building block for life on earth.Achondrites: Stony meteorites without chondrules, representing about 7.1% of meteorites. Scientists believe that some of these meteorites originate on the surface of the Moon or Mars.From http://www.odec.ca/projects/2006/jauc6s2/kinds.htm

What did scientist find in the meteorite at Allende Mexico?
Besides common minerals found in this kind of meteorites (calcium, aluminium, titanium), they found small traces of carbon (graphite and diamond) and some organic compunds, including some amino-acids not known on Earth.

Explain how the carbon cycle works?
Carbon is the element at the base of all known life in the universe. The carbon cycle begins with carbon received on Earth from meteorites and continues with the normal death and decay of organic life.
