Some have speculated that the origin of life occurred at geothermal vents. amino acids can form there. compared to the amino aci
cluponka [151]

There are a number of amino acids that have formed under certain environmental conditions if the required elements are present and the energy conditions ar compatible with chemical assembly. These conditions have also allegedly formed amino acids on meteors, asteroids and comets.


But, amino acids are a very minor component of more complex biochemical assemblies required for life. Pentose sugars are also required, which form under different environmental conditions than amino acids. More importantly, only left-handed homochiral amino acids and right-handed homochiral sugars can form functioning biochemical assemblies that are viable in an organism. But, natural conditions, like hydrothermal vents only produce racemic versions of sugars and acids, meaning they are always approx. 50% left and right handed. This is fatal to forming viable biochemical assemblies.


Further, it is not possible for all of the 20+ homochiral amino acids needed for a living organism to form naturally. The only ones found have been the simpler amino acids. Also, the 4 critical nucleotide amino acids, C, G, A, T, do not form naturally, are not homochiral, nor in the right proportions.


The geo/hydrothermal vent conjecture is nonsensical. These are open systems, susceptible to currents, mineral contamination, salinity, ph, and temperature, making them a totally unacceptable environment for the precise and exact placement of elements to assemble to form life.

What takes place when you inhale?
bezimeni [28]

Explanation:

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale
