The nutrients that the body breaks down into basic units are carbohydrates, fats, and proteins. From carbohydrates comes glucose, your body's -- especially the brain's -- primary form of fuel; from fats we get glycerol and fatty acids, many of which are essential ingredients in hormones and the protective sheath in our brain that covers communicating neurons; and from proteins we get amino acids, which are the building blocks to lots of structures, including our blood, muscle, skin, organs, antibodies, hair, and fingernails.
Each of these nutrients travels down a different pathway, but all can eventually fuel the body's production of ATP (adenosine triphosphate), which is essentially our bodies' ultimate energy currency.
<span>the one that is not a factor that contribute to natural selection is : Population stability
population refer to the capability of a community to maintain its total amount of organisms within a specific period of time.
This has nothing to do with natural selection, which basically a nature's way to reduce the number of organism to findout which organisms are more adaptive</span>
<h3>The enthalpy of the reaction : C.226.73 kJ</h3><h3>Further explanation</h3>
Delta H reaction (ΔH) is the amount of heat change between the system and its environment
(ΔH) can be positive (endothermic = requires heat) or negative (exothermic = releasing heat)
The change in enthalpy in the formation of 1 mole of the elements is called enthalpy of formation
Delta H reaction (ΔH) is the difference between product enthalpy and reactant enthalpy (Hp-Hr)
Reaction :
2C + H2 -> C2H2
(ΔH) reaction = (ΔH) product - (ΔH) reactants
(ΔH) reaction = (ΔH) C2H2 - ((ΔH) C + (ΔH) H2)
for free element (ΔH) it has zero value, so (ΔH) C and (ΔH) H2 have zero value
From the available data: Hf (kJ / mol) C2 H2 (g)= 226.73
then
(ΔH) reaction = ΔH) C2H2 - ((ΔH) C + (ΔH) H2)
(ΔH) reaction = 226.73 - (0 + 0)
(ΔH) reaction = 226.73 (answer C)

Mass of Sulphur dioxide : 256 g
<h3>Further explanation</h3>
Given
Reaction
S + O2 --> SO2 *
Required
Mass of Sulphur dioxide
Solution
mol of Sulphur (Ar=32 g/mol) :
mol = mass : Ar
mol = 128 : 32
mol = 4
From the equation, mol ratio S : SO2 = 1 : 1, so mol SO2 = 4
Mass of SO2 :
mass = mol x MW SO2
mass = 4 x 64
mass = 256 g
