The following causes increase the activity of the electron transport chain:
1. High ADP concentration
2. Large differences in H+ concentration across the inner mitochondrial membrane
3. High phosphate concentration
The following causes decrease the activity of the electron transport chain:
1. Low oxygen concentration
2. Low NADH concentration
A monocrop is a non example of biodiversity because it contains only one species, such as all corn, therefore there is very little biodiversity.

Explanation:
The number 4 in the hydrologic cycle depicts surface runoff.
The hydrologic cycle depicts the cyclic movement of water between different earth components.
It shows water in all its phases.
- From the attached image, runoff is depicted 4.
- Runoff is water that moves on the surface after precipitation.
- Number 1 is evaporation where water changes to vapor.
- Number 2 is condensation where the vapor cools back to liquid.
- Number 3 is precipitation where the liquid water is forced down under gravity.
- On the surface, the water runs as runoff.

Answer:
2
Explanation:
Mass of water molecule = mass of hydrated salt - mass of anhydrous salt
Mass of water molecule = 5.00 - 4.26 = 0.74g of water molecule.
Number of moles = mass / molarmass
Molar mass of water = 18.015g/mol
No. of moles of water = 0.74 / 18.015 = 0.0411 moles.
Mass of BaCl2 present =?
1 mole of BaCl2 = 208.23 g
X mole of BaCl2 = 4.26 g
X = (4.26 * 1) / 208.23
X = 0.020
0.020 moles is present in 4.26g of BaCl2
Mole ratio between water and BaCl2 =
0.0411 / 0.020 = 2
Therefore 2 molecules of water is present the hydrated salt.

Explanation:
In order to aid understanding of the question, let me put the words into a proper chemical reaction equation.
aA + bB ⇄cC + dD
We must recall that the equilibrium constant often designated as Keq is given as;
Keq= product of the concentration of product species raised to the power of their respective molar coefficients / product of the concentration of reactant species raised to the power of their respective molar coefficients
Hence from what was written above, I can safely write;
Keq= [C]^c [D]^d / [A]^a [B]^b
This has been represented in words in the answer given above.
