A star remarkably ruptured about 7,500 years ago established about 6,500 light years away. 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.
Due to convergent evolution placental mammals (Wolf) are closely related to marsupial wolves (Tasmanian wolf). No, the tree is wrong.
What is convergent evolution?
It is the presence of similar features in animals of different lineages. The structures in these animals have similar functions but are absent in the common ancestors hence they are analogous structures not homologous.
Such convergence of functional, morphological, and structural traits from phylogenetically unrelated species may be a result of random mutation due to selection pressure.
Here, the Tasmanian wolf (marsupial wolf) and wolf (placental mammal) have several morphological similarities but they have unrelated ancestral lineages. Hence they show convergent evolution. These two subclasses of mammals have adapted to a specific food source, locomotor ability, or environment in similar ways.
Hence, the placental wolf and Tasmanian wolf exist sharing the same habitat in different continents former in Asia and the latter in Australia because these two show convergent evolution.

Eukaryotic chromosomes contain both DNA and protein tightly packed together to form Chromatin.
Answer:
DNA sequencing – to identify bacteria, moulds and yeasts. Riboprinter analysis – for bacterial identification and characterisation. Repeat–based polymerase chain reaction – for assessing the similarity of microorganisms. Rapid pathogen confirmation by polymerase chain reaction.
