The Hubble sequence is a form of classification of galaxies invented by Hubble in 1926. The sequence divides galaxies into three main categories: lenticular, elliptical and spiral. There is a fourth category that is called irregular, where there are the galaxies that do not fit the characteristics to be included in the three previous categories.
This categorization is the most used even today by both amateurs and astronomers.

When exposed to smoke, hydrogen cyanide may play a role in rendering firemen and bystanders incapable of performing self-rescue.
HCN is a toxin that spreads throughout the body; it is hazardous because it inhibits cytochrome oxidase, which stops cells from using oxygen. Loss of awareness, respiratory arrest, and finally death arise from inhibition of the last stage of electron transport in brain cells.
Higher HCN exposures cause cardiovascular collapse, tremors, cardiac arrhythmia (which may not manifest for two to three weeks after the fire exposure), coma, respiratory depression, and respiratory arrest. Inhaling minute concentrations of hydrogen cyanide can result in headaches, weakness, nausea, and vomiting. Larger doses might result in fainting, convulsions, gasping, fast pulse, irregular heartbeat, and even death. In general, the severity of the symptoms increases with the seriousness of the exposure.

Answer: Ghareeb Nawaz, or reverently as a Shaykh Muʿīn al-Dīn or Muʿīn al-Dīn or Khwājā Muʿīn al-Dīn (Urdu: معین الدین چشتی) by Muslims of the Indian subcontinent, was a Persian Muslim[3] preacher,[6] ascetic, religious scholar, philosopher, and mystic from Sistan,[6] who eventually ended up settling in the Indian subcontinent in the early 13th-century, where he promulgated the famous Chishtiyya order of Sunni mysticism.[6][7] This particular tariqa (order) became the dominant Muslim spiritual group in medieval India and many of the most beloved and venerated Indian Sunni saints[4][8][9] were Chishti in their affiliation, including Nizamuddin Awliya (d. 1325) and Amir Khusrow (d. 1325).[6] As such, Muʿīn al-Dīn Chishtī's legacy rests primarily on his having been "one of the most outstanding figures in the annals of Islamic mysticism."[2] Additionally Muʿīn al-Dīn Chishtī is also notable, according to John Esposito, for having been one of the first major Islamic mystics to formally allow his followers to incorporate the "use of music" in their devotions, liturgies, and hymns to God, which he did in order to make the foreign Arab faith more relatable to the indigenous peoples who had recently entered the religion or whom he sought to convert.[10] Others contest that the Chisti order ever permitted musical instruments and a famous Chisti, Nizamuddin Auliya, is quoted as stating that musical instruments are prohibited.
