As the early earth had no ozone layer, or a very weak one, UV rays could have reached the surface of the earth and provided energy and heat. Other than UV rays, the hydro-thermal vents of the very volcanically active early earth period are an option as well.
It sounds like you are talking about some experiments done many years ago attempting to replicate the conditions thought to be present at the time that life appeared on earth. Special flasks were filled with certain gases and liquids and then exposed to electricity (standing in for lightning). The experiment did not form living cells, but as I recall there were some interesting structures found in the resulting mixture.
He found out that some traits in one generation (parents) was not present in the next generation (offspring).
the traits were recessive
It is telomerase
The famous Stanley Miller experiment used a flask, an electrical discharge to simulate lightning, and molecules of everyday substances like water, ammonia, and methane. In other words molecules that are present in nature and their components are present in DNA. The theory was that the early earth was a volatile place with large amounts of the basic molecules and at one phase in the earths evolution constant storms and lightning. The experiment successfully produced some amino acids. Given the vast amount of time there was an opportunity for billions of trillions of different combinations of these molecules and that a chance "stringing together" of these amino acids capable of replication could occur. The first self replicating proto life may have been proteins, viruses, prions, enzymes or all the above. The smallest structures in the DNAverse.
That would be Benjamin Franklin. Do not try that at home.
After the experiment, scientists organize and analyze the data. Which therefore means that the scientists will create something to tell what is going on with there experiment and how long it goes for and if anything improved or something changed.
a.) Bacteria was present on the meat at the start of the experiment.
to present the starch.
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.
The Stanley-Muller experiment didn't prove that life formed from those elements, just some common and simpler amino acids, some of which are present in DNA.
When conducting experiments in science, it is important to have a baseline for knowing what happens if an independent variable is not present. In science, this is called the control experiment.
No. As a matter the fact, the ABSENCE of anti-matter in our Universe is a problem scientists are still trying to explain. We know that anti-matter is almost non-existent here, but our present theories can give no reason why that should have happened -- any more than our present scientific theories can explain where lightning comes from. In both cases, scientists are working on developing better theoretical understanding.
There are many characteristics present during a good experiment. For example, if the experiment provides unbiased estimates for uncertainties and factor effects then the experiment should be considered good.

Lightning usually occurs when is rains, sleets, hails etc, most comonly when there is a thunder storm. Dry lightning simply means that there is not rain present when the lightning occurs. Hope that helps
It turns blue-black if starch is present.
