Genetic recombination refers to the process by which two DNA  molecules exchange genetic information. The three types of genetic  recombination are crossing over, conservati â¦ ve site-specific  recombination and transpositional recombination.
This produces a crystal lattice, which is commonly known as 'ice'. Ice floats because it is about 9% less dense than liquid water. In other words, ice takes up about 9% more space than water, so a liter of ice weighs less than a liter water. The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over.
In order for you to float, the water that moves out of the way to make room for you must weigh as much as you do. Since you are lighter (less dense) than water, the water pushes you up enough for you to float. The Dead Sea has a LOT of salt in it.Salt water is heavier (denser) than regular water. People can float in regular water, but since salt water is even denser, it is even easier to float in the Dead Sea. Adam. (published on 10/22/2007).
