Can someone me with this ? i need this > analyze the structure in the diagram and explain how living systems use this structure. be sure to include the following points in your 1) a description of the important properties of the structure in the diagram. 2) an explanation of how the structure functions in the cell. 3) an explanation of how the structure regulate materials in living systems. 4) a prediction of how water will move from one side of the structure to the other side.

1) The structure shown is of a cell membrane. A cell membrane is made up of phospholipid bilayer. The head of the bilayer are made up of phophates and glycerol which are facing outward. The tail is made up of fatty acids which is enclosed in the layers. The cell membrane also comprises of cholesterol and membrane proteins.

2) The cell membrane is semi-permeable. It allows the entry of specific molecules into the cell and exit specific molecules only.

3) The cell membrane helps to regulate the specific entry of molecules into a cell. By doing so, it acts like a filter for the cell and allows the entry of those materials which are required by the cell.

4) Water moves through the cell membrane by osmosis. Osmosis can be described as the movement of water molecules from an area of higher concentration to an area of lower concentration along the concentration gradient.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]

i think the answer is b.
