(Help Please It Will Mean So Much!) Procedure: Using potatoes and salt water to take a look at transport across membranes. For the experiment shown, you are going to need to use a cork borer to drive away strips of potatoes and then nicely cut them accordingly, that many should to be the same length. Next you are going to get 6 beakers and every will have three strips of potatoes with a 1 to 5 g of salt and hundred mL water ratio (one beaker getting a 0:1 ratio, becoming the control). Then leave the potatoes for some time as well as measure once the time is actually up. You are going to record the dimensions as well as compute the percentage change for every strip. After, you're able to graph the results of yours to see the higher length of potato strips triggered by osmosis. In a well-structured paragraph, write an description of a controlled procedure for investigating the new aspect of transport across membranes you've proposed.

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

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]
