An EGD may be performed therapeutically to control bleeding, remove tumors or polyps (growths), dilate narrowed areas in the upper GI tract (for example, esophagus), remove foreign objects, perform laser therapy, and place a percutaneous gastrostomy tube (a tube used for tube feeding into the stomach).
Navel oranges ripen in the winter and into the spring and early summer, while Valencia oranges begin ripening in the spring and are harvested through the summer. Mandarin Mandarins are more tolerant of cooler temperatures than are many varieties of sweet orange, and they require only moderate heat to ripen well, making them, along with lemons and limes, well suited to northern climates and cool coastal locales.
The orange colour of carrots, pumpkins, sweet potatoes, oranges, and many other fruits and vegetables comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the sun into chemical energy for the plants' growth.
