Answer:
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.
Amino-acid racemization is primarily used to date samples of bones, applicable beyond the time of range of radiocarbon dating. Amino-acid Racemization, the AAR rates not only change of the temperature but also with the concurrent effects of pH changes. L-amino acid is an example of racemization which is the process <span>in which one enantiomer of a compound.</span>
This enzyme facilitates the removal of an <u>amino group</u> from the organic compound so it can be converted into an intermediate compound for the krebbs cycle.
<u>Explanation:</u>
An organism’s ability to produce the enzyme deaminase can be tested using the phenylalanine deaminase medium. Phenylalanine is an amino acid that contains amino group. The enzyme deaminase removes the amino group from this as free ammonia.
In the testing medium containing phenylalanine 10% ferric chloride is added after sufficient incubation. In the case of organisms that produce deaminase enzyme they phenyl pyruvic acid will be produced in the medium. This phenyl pyruvic acid will then react with ferric chloride and turn dark green.
In organisms that do not produce the enzyme no such reaction will take place and the medium will maintain the straw color.
