Explanation:
During the early earth, when photosynthesis has not yet evolved, there were only negligible amounts of free oxygen in the atmosphere. It was said that the Earth's atmosphere had no free oxygen then. This is about 3.5 billion years ago.
A. The law includes the presumption of innocence and the freedom of speech and religion. The UAE constitution is influenced from Sharia law and though the freedom to exercise one's religion is generally tolerable, any criticism of the government, royal family, police and/or authority will be severely punished, making freedom of speech highly regulated in the country. Gender equality is also emphasized and women are allowed to serve in higher positions of government along with their male counterparts.
The justification hypothesis that the early Earth environment was void of oxygen is:
- atmosphere lacked oxygen but abundant in methane, ammonia, water vapour, noble gas, neon etc.
