Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The name of the group that consists only of modern humans and their direct ancestors is known as Hominidae. It is also called by the name of Hominids or great apes. Originally the term Hominidae referred to only the humans and their closest relatives. There are still people that continue to use this term in its restricted sense, rather than the modern sense.<span />
Answer:
Precipitation and runoff
Explanation:
The oceans get water in several different manners, with some of them being through precipitation, and through runoff. Whenever there is precipitation on the ocean waters, the water from it of course ends up in it, thus it accumulates it. Also, when there's precipitation on the land, a runoff appears. The runoff is simply the water from the precipitation that moves on the surface, downhill, and usually ends up in some water body. Part of the runoff ends up in the oceans, and that is the runoff that appears on the slopes that are near the ocean and are sloping toward the ocean waters.
