Complete the reaction, which is part of the electron transport chain. The abbreviation FMN represents flavin mononucleotide. Use

the appropriate abbreviation for the product. NADH + H + + FMN ⟶ NAD +FMNH_{2} NAD + FMNH 2 The reactant that is reduced is FMN . In complex III, electrons are transferred from coenzyme Q to cytochrome c, which contains iron. QH 2 + 2 cyt c ( Fe 3 + ) ⟶ Q + 2 cyt c ( Fe x ) + 2 H + Determine the oxidation number for iron on the right side of the reaction arrow.

Answer:

Oxidation number of Fe(iron) on right side of reaction arrow = (+2)

Explanation:

NADH+H+ + FMN   FMNH2 + NAD+

FMNH2 - Reduced FMN (1,5-Dihydroriboflavin 5'-(dihydrogen phosphate)

The reactant that is reduced is Flavin mononucleotide(FMN)

QH2 + 2cyt c(fe³+)  ----------------------->  Q + 2Cytc ( fe²+) + 2H+

Oxidation number of Fe(iron) on right side of reaction arrow = (+2)

A geologist finds an area with a lot of slate, a type of metamorphic rock, on the surface of the land. What might this indicate
Elan Coil [88]

Answer:

Explanation:

Two things that can be deduced by this finding would be that the location was most likely a very muddy area with lots of clay minerals, as well as having lots of crustal movements. This is because slate is created when crustal movement buries clay minerals and other materials in the crust of the Earth. This is later melted and squeezed together from the sheer heat that is applied  being so far underground. Therefore, creating what we now know as Slate.
