Polyandry
When you blow out a normal candle,you see thin smoke rising up. The wick is hot enough to vaporize the wax but not hot enough to re-ignite it.
In trick candles however, they add an ingredient that ignites at a lower temperature then the paraffin wax. This ingredient is usually a pyrophoric metal(metals which ignite at extremely low temperatures).
MAGNESIUM is the most commonly used pyrophoric metal in trick candles, with the magnesium flakes embedded in the wicks. When you blow out the candle, the wick that remains is hot enough to light off the magnesium and the burning process continues.
Polygamy (one man several wives) has been in practice for several thousand years. But did you know even Polyandry (one wife several husbands) is present in Tibet and some tribal places of India. Fraternal polyandry (like Draupadi of Mahabharata , one woman gets married to all brothers) is still practiced in Jaunsar-Bawar tribals in Uttarakhand. Todas are tribal people residing in the Nilgiri hills in South India who once practiced polyandry.
Junk DNA makes up around 98% of human genome. Junk DNA is also termed as non-coding DNA many times. This DNA does not produce proteins .Recent researches establish that junk DNA plays a significant role in human lives, even if it is not having functional activity. Changes in junk DNA leads to structural changes in the genome. Further it is said that junk DNA in humans play crucial roles in evolution. A geneticist, Susumu Ohno, was the first to coin the term “junk” DNA in 1972. A massive project called ENCODE, which aimed to uncover its role found junk DNA really isn't needed for healthy plants but same may not be the case for
