Steam distillation is a separation process for temperature sensitive materials and it is used for purification of organic compounds.
The water vapor carries small amounts of the vaporized compounds (water and organic molecules) to the condensation flask. This is preferred technique because allows easy separation of the components by decantation or other suitable methods, because product od distilation is a two phase system<span> of water and the organic distillate.</span>
Atomic size gradually decreases from left to right across a period of elements.
Answer: biological adaptation
Explanation:
lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.
I hope this helps :).
