Human papillomavirus. You need this vaccine if you are a woman age 26 years or younger or a man age 21 years or younger. Other men age 22 through 26 who want to be protected from HPV may receive it, too. Men age 22 through 26 years with a risk condition also need vaccination.
The benthic zone is the area near to the bottom of river, lake or sea. Most of the plants found there are algae and seagrasses, which are also called phytobenthos.Phytobenthos will occur more often in the superior levels of the benthic zone, since they depend on the sun for photosynthesis.ost of the plants found there are algae and seagrasses, which are also called phytobenthos.

In oceanic environments, benthic habitats are zoned by depth, generally corresponding to the comparable pelagic zones: the intertidal (where sea meets land, with no pelagic equivalent), the subtidal (the continental shelves, to about 200 m), the bathyal (generally the continental slopes to 4,000 m), the abyssal (most of the deep ocean seafloor, 4,000 - 6,000 m), and the hadal (the deep trenches 6,000 to 11,000 m).
