The surface zone has the ocean's least dense water and represents approximately 2% of the total volume of ocean water. The surface zone usually ranges between depths of 500 feet to 3,300 feet below ocean surface, but this can vary a great deal.
A hypha (plural hyphae, from Greek á½ÏÎ®, huphá¸, âwebâ) is a long, branching filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Yeasts are unicellular fungi that do not grow as hyphae.
A stye is a sore and red lump near the edge of an eyelid. It is caused by an infection at the base of an eyelash (in the follicle). Staphylococcal bacteria are the usual culprits. These bacteria normally live harmlessly on the skin, but they can cause infection if the skin is damaged.
