Answer is: humus.

Humus is the dark organic matter that forms in soil when dead plant and animal matter decays.

Microorganisms decompose the soil organic matter into inorganic minerals that the roots can absorb.

Humus can hold a lot of moisture (approximately 80–90% of its weight) and its dark color helps to warm cold soils.

The answer is; Humus

Humus is found in the topmost layer of the soil where there is decomposing organic matter. This layer of soil has a characteristic color of dark brown to black. This layer of soil also teems with microbial activity and organisms such as earthworms, fungi, and arthropods which are significant in the decomposition of the dead organic matter.

The compound : C₄₀H₄₄N₄O

<h3>Further explanation</h3>

The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components

The principle of determining empirical formula

• Determine the mass ratio of the constituent elements of the compound.

• Determine the mole ratio by dividing the percentage by the atomic mass

The mol ratio of composition : C : H : N : O

$\tt \dfrac{80.66}{12}\div \dfrac{7.39}{1}\div \dfrac{9.39}{14}\div \dfrac{2.68}{16}\\\\6.722\div 7.39\div 0.671\div 0.1675\rightarrow divide~by~smallest(0.1675)\\\\40\div 44\div 4\div 1$

Which of the following is/are correct regarding the pentose phosphate pathway? I. NADH is generated by the oxidation of glucose-

fgiga [73]

Answer:

The correct answer is 1 NADH is generated by the oxidation of glucose-6-phosphate.

Explanation:

Pentose phosphate pathway deals with the utilization of glucose-6-phosphate by oxidation process to form 6-phosphogluconolactone by the catalytic activity of glucose-6-phosphate dehydrogenese.

This enzyme need NAD+ as co enzyme which get reduced to generate NADH.
