The explosion states that the star was brighter than million suns and it was visible during day light which amazed the Chinese astronomers. There were amazed at the appearance of the bright star. Many years later, the arrival of the telescope, astronomers launch a nebula which is a cloud like structure and that it is a remnant of  a shattered star. The astronomers detected the promptly rotating neutron star - a pulsar surrounded by a gas envelope. Now Indian astronomers, combine powerful Cadmium-Zinc-Telluride imager on the on panel the indian astronomy satellite, AtroSat, have achieved  the most absolute X-ray polarization measurement of the Crab nebula.

ehidna [41]

     This is a very good question and the answer to it is option A. The common core set of genes is very similar between all organisms.

      This is true because several facts, for example, all living beings on earth share the same gene code: DNA, all of them are based on DNA or RNA, which humans have it too. This was explained by Darwin's evolution theory, we are all descendants of just one single species, and because of that, all species have something in common between them.

       That's why there's a possibility that a human gene can correct a defective gene in a yeast cell. Although this could really happen, we are not sure about it, it's a possibility, don't always be sure of something in biology, there's always more to understand and to learn.
