Why does papaya and corn use cross pollination

Genetically engineered crops are conventional crops that have been genetically altered by the inten­ tional introduction of one or more genes from another organism, usually a different species, to improve the ag­ ricultural quality and value of the crop. Genetic engi­ neering is a relatively new plant breeding tool that has been used extensively in the USA since 1994, when the first genetically engineered variety, the FlavrSavrTM to­ mato, was released for commercial production

A water molecule's bent shape makes it polar (slightly positive on the hydrogen end and negative on the oxygen end). This polarity is strong enough to pull apart the ions of many ionic compounds. It can also pull apart some covalent compounds (like sugar).
