In the given case, a similar amount of colonies is witnessed in both control as well as the test plate. This concludes that it does not influence the organism, thus, there was no enhancement in the rate of reversion, that is, the number of colonies in the test plate does not get decrease. Thus, the compound in the disc is not mutagenic as there was no increase in the reversion rate.
R136a1 and our Sun both are made of the same compounds and molecular build, however R136a1 is 261 times bigger and the mass is approx. 261 times greater than our Sun's mass.
It depends on the tempature but at 100% that means it is raining so D.
