The right answer is A. It requires more coal mining.
In order to manufacture synthetic gasoline, the Fischer-Tropsch process involves the catalysis of carbon monoxide and hydrogen to convert them to hydrocarbon. In this chemical process, the most common catalysts are iron, cobalt or ruthenium, as well as nickel, but the latter will tend to form methane CH4 (this is called methanation). The interest of conversion is to produce synthetic crude oil from coal or gas. This process has a very good yield but requires very heavy investments, which makes it economically vulnerable to downward fluctuations in the price of oil.
Answer:
Option A, Forms a helix and no branch points
Explanation:
As we know that amylose is a straight chain molecule, therefore it forms helix and consists of branching. This is the reason why amylose has no branch points.
However, amylopectin is a branched chain molecule polymer. The monomer unit in both amylose and amylopectin is glucose - D connected at 1, 4 carbon . The number of glucose molecules are higher in amylopectin than the amylose.
Hence out of all given options, option A is correct
Answer:
Helium has many unique properties: low boiling point, low density, low solubility, high thermal conductivity and inertness, so it is use for any application which can exploit these properties. Helium was the first gas used for filling balloons and dirigibles.
<span>The increase in the use of wind energy does not have to affect the energy supply of coal, since they are not related in any way and do not depend on each other. It's totally out of logic. They are different energies, the wind energy should not affect the energetic consumption of coal for the simple fact that coal is not necessary to produce wind energy, but it could be said that the demand for coal could be reduced by a small percentage only If the wind energy is used much more.</span>
