Answer:
Nuclear fuel has a higher energy density than fossil fuel
Explanation:
Cholesterol concentration = 27 mg/ 232 mL
Change unit mg/ml to kg/m³
1 kg = 1000 g
1 g = 1000 mg
1 kg = 1000000 mg
1 kg = 10⁶ mg
10⁶ mg = 1 kg
1 mg = 10^-6 kg
m³ = 1000 L
1 L = 1000 mL
m³ = 1000000 mL
m³ = 10⁶ mL
10⁶ mL = m³
1 mL = 10^-6 m³
Cholesterol concentration = 27 mg/ 232 mL
27 × 10^-6 kg/ 232 × 10^-6 m³
= 27/232 kg/m³
Each mole of nitrogen that microbes fix requires the breakdown of 16 moles of ATP (adenosine triphosphate). The energy needed by these microbes is obtained by oxidizing organic compounds. In other words, the nitrogenase enzyme must use a significant amount of energy to convert N2 to NH3.
The great majority of nitrogen on Earth exists as molecular N2, and before to the agricultural and industrial revolutions, the only significant mechanism producing reactive nitrogen was biological nitrogen fixation. Any natural or artificial process known as nitrogen fixation causes free nitrogen (N2), a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites. carbon cycle.
