Sentences with phrase «terrestrial life uses»

Terrestrial life uses the left - handed versions, while non-biological chemistry produces the left - handed and right - handed varieties in equal amounts.

Not exact matches

Mangrove rivulus, which can live out of the water for extended periods of time (days or weeks, as long as the conditions are moist), uses its specialised jumping technique when water has low oxygen concentrations or high levels of hydrogen sulphide, or to escape predators and search for terrestrial prey such as crickets.
Last year, scientists in Denmark showed that terrestrial leeches can be used similarly to sample an area's fauna, though they feast on fewer species than do carrion flies, don't travel as far in search of prey, and live in only certain habitats.
Life prefers to use the lighter Carbon - 12, which reacts a bit more readily, so amino acid molecules from terrestrial life will have less Carbon - 13 compared to amino acids produced by non-biological reactions in asteroLife prefers to use the lighter Carbon - 12, which reacts a bit more readily, so amino acid molecules from terrestrial life will have less Carbon - 13 compared to amino acids produced by non-biological reactions in asterolife will have less Carbon - 13 compared to amino acids produced by non-biological reactions in asteroids.
Since life uses the left - handed versions, this suggests terrestrial life as the source of these amino acids.
In late September 2003, astrobiologist Maggie Turnbull from the University of Arizona in Tucson identified 37 Geminorum as one of the best candidates for hosting Earth - type life from a shortlist of 30 stars (screened from the 5,000 or so stars that are estimated to be located within 100 ly of Earth) that were presented to a group of scientists from NASA's space - telescope project, the Terrestrial Planet Finder (TPF), which will search for habitable planets by using visible light with the «signature» of water and / or oxygen from an Earth - type planet after its scheduled launch around 2013, and the ESA's Darwin project involving six space telescopes (Astrobiology Magazine).
GOAL 15 — Life on Land — Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss.
Keeping in mind, the model is greatly simplified at only 3 bodies from our own actual system of interacting ocean oscillations and ocean life and ocean chemistry, terrestrial conditions and terrestrial life, solar variability, orbital variability, land use, anthropogenic aerosols, and GHGs, any of which might suffer the eventual fate of a body in the 3 Body problem: ejection or collision more rapidly with larger perturbation, and all of which are more certain to follow irregular and extreme paths.
Oxygen is an important part of the atmosphere, and is necessary to sustain most terrestrial life as it is used in respiration.
