The most common application of genetic engineering of foods is to confer resistance to pesticides used to eradicate weeds and insects.  

The GM foods or genetically modified foods also called genetically engineered foods refers to the foods generated with the help of organisms, which have created modifications into their DNA with the applications of genetic engineering.  

The method is followed for the production of improved varieties of vegetables, fruits, and food crops. One of the major application is to develop resistance against certain pesticides, weedicides, and insecticides, which are used in crop fields to kill unwanted weeds or grass and other harmful insects.

explanation:

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
