What discovery would weaken the primordial soup hypothesis of the origin of life? question 19 options: lightning was common on early earth. earth’s early atmosphere contained carbon dioxide, water, and trace gases. earth’s early oceans were warm and shallow. asteroid impacts were uncommon when life is presumed to have begun.

Asteroid impacts were uncommon when life presumed to have happened

Explanation:

The primordial soup hypothesis is based upon the impact that the asteroids had on Earth and the development of life on it. The hypothesis suggests that the asteroids were carrying the basic ingredients for life to develop, so they ''seeded'' the earth with life. Also, this hypothesis suggests that there were constant bombarding by asteroids, so they brought in lot of organic material with them. If it is proven wrong that there were lot of asteroids falling on Earth at the period when life is presumed to have begun, but instead that they were very few, this hypothesis will easily be dismissed. The reason why it will easily be dismissed is that it will lose the base around it is formed, and without it, it will have nothing as its basis.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
