The lungs and the remainder of the respiratory tract are exposed to the highest concentration of oxygen in the human body and are therefore the first organs to show chronic toxicity. [28] Pulmonary toxicity occurs only with exposure to partial pressures of oxygen greater than 0.5 bar (50 kPa), corresponding to an oxygen fraction of 50% at ...
Human evolutionary genetics studies how one human genome differs from another human genome, the evolutionary past that gave rise to the human genome, and its current effects. Differences between genomes have anthropological , medical , historical and forensic implications and applications.
Honor cultures pervade in places of economic vulnerability and with the absence of the rule of law, where law enforcement cannot be counted on to protect them. People then resort to their reputations to protect them from social exploitation and a man must "stand up for himself" and not rely on others to do so. [103]

This is why summer monsoons cause so much rain over land. In the colder months, the cycle is reversed. Then the land cools faster than the oceans and the air over the land has higher pressure than air over the ocean. This causes the air over the land to flow to the ocean.
Colonization of Mars differs from the crewed Mars exploration missions currently pursued by public space agencies, as they aim to land humans for exploration. [6] [7]The terminology used to refer a potential human presence on Mars has been scrutinized since at least the 2010s, [4] with space colonization in general since the 1977, as by Carl Sagan, who preferred to refer to settlements in ...
