Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.
In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.
These are sometimes known instead as mineral fuels.
The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.
A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.
I think the molecules that will easily <span>dissolve in water based on polarity not on size would be as follows:
</span><span>CH and small 3 with H OH
</span><span>CH and small 2 with H OH
These molecules would indicate they are alcohols which are definitely soluble in water. Hope this helps. Have a nice day.</span>
Answer:
Seeds and fruits are formed by fertilization. In angiosperms, two structures are formed as a result of double fertilization – a diploid zygote and a triploid primary endosperm cell. The zygote develops into an embryo, whereas, the endosperm cell gives rise to endosperm. It provides nourishment to the growing embryo. Both fruits and seeds are an important part of angiosperms...
Hope it helps XD...
Answer:
Oxygen is obtained from photosynthesis process.
Explanation:
Oxygen is one of the most important element required for survival of living organism. Living beings inspire oxygen and expire carbon dioxide which is collectively called as respiration and is considered as most important biological process.
Plants prepare their own food through the process called photosynthesis. It is process through which the plants uses carbon dioxide and water as reactants and gives out glucose and oxygen as the end product.
The released product is sugar and gas, in which the sugar is consumed as food by other living organism and the gas called oxygen is used for respiration and other biological process. Thus it can be inferred that oxygen is obtained from process called photosynthesis.
