The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.
What are microorganisms?A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.
“Microorganisms are minute organisms that are invisible to the normal eye.” Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc.
Given options are-
A. adding manure or compost to the soil
B. spraying chemical weed-killers and fertilizers on the soil
C. removing all ground-covering plants from the soil
D. adding sewage containing synthetic materials to the soil
Therefore, The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

Plate Tectonics Independent Practice,
Label The Diagram With The Correct Information.
Answer:
1st Diagram (at the left) → Mid-Atlantic Ridge
2nd Diagram (at the right) → Andes Mountains
3rd Diagram (below) → San Andreas Fault
Explanation:
I have been able to label the diagram with the correct information.
The 1st diagram at the left is the Mid-Atlantic Ridge. This is a divergent plate boundary that is found at the floor of the Atlantic Ocean. It is also seen as part of the mountain range in the world. The Mid-Atlantic Ridge also includes a deep rift valley. This rift valley runs along the axis of the ridge. This is along nearly its entire length.
The Andes Mountains is found along the Pacific Ring of Fire. It is seen in a Mesozoic–Tertiary orogenic belt of mountains. The Andes rises due to the compression of the western rim of the South American Plate. It is a result of tectonic plate processes.
San Andreas Fault is known to form the tectonic boundary which exists between the Pacific Plate and the North American Plate. The motion of the fault is right-lateral strike-slip. It divides into three segments.

A sample of unknown gas has a temperature of 378k. When the temperature is increased to 546k,the volume also increases to 1047 ml. What was the original volume ?
Given :
A sample of unknown gas has a temperature of 378 K.
[tex]T_i = 378 \ K , \ T_f = 546 \ K[/tex]
When the temperature is increased to 546 K, the volume also increases to 1047 ml.
[tex]V_f - V_i = 1047 \ ml[/tex]
Solution :
We know, temperature is directly proportional to volume.
[tex]\dfrac{T_i}{T_f}=\dfrac{V_i}{V_f}\\\\\dfrac{T_i}{T_f} = \dfrac{V_i}{1047 + V_i}\\\\\dfrac{V_i}{1047+V_i}=\dfrac{378}{546}\\\\546V_i = 378V_i + 378\times 1047\\\\168V_i = 3,95,766\\\\V_i = 2,355.75\ ml[/tex]
Therefore, the original volume is 2.355.75 ml.

Would a rollercoaster have the greatest kinetic energy at the top of the highest hill or at the bottom on the highest hill
Answer:
The rollercoaster has the lowest kinetic energy at the top of the hill.
The rollercaoster has the highest kinetic energy at the bottom of the hill.
Explanation:
The kinetic energy of any solid body in motion is usually computed using this formula:
K.E = [tex]\frac{1}{2}mv^2[/tex]
From this, we can see that it varies based on two major parameters - The mass of the moving object and the velocity of the moving object.
We can assume that the mass of the rollercoaster is constant since no one gets off and it does not shrink in its size during the ride.
This means that the variations in the K.E are mainly coming from its velocity.
At the top of the hill, the rollercoaster is moving at its slowest pace. hence, it has the lowest kinetic energy at the top of the hill.
However, at the bottom of the hill, the rollercoaster is moving its fastest, hence it has the highest kinetic energy at the bottom of the hill.

Answer:
See explanation
Explanation:
When we are writing chemical reaction equations, we must ensure that such equations are balanced. That is, the number of atoms of each element on both sides of the reaction equation are exactly the same.
After we identify the formula of each compound in the reaction, then we proceed the write the balanced reaction equation as follows;
CuCl2 + 2AgNO3 -------> Cu(NO3)2 + 2AgCl

1.9x10^23 atoms of sulfur to grams of sulfur
Answer:
see explanation and punch in the numbers yourself ( will be better for your test)
Explanation:
If you are given atoms you need to divide by Avogadro's number 6.022x10^23
then you will have moles of sulfur-- once you have moles multiply by the molar mass of sulfur to go from moles to grams
mm of sulfur is 32 g/mol
Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, the grams of sulfur in 1.9x10²³ atoms of sulfur is 9.92g.
What is mole?The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance.
Given number of atoms= 1.9x10²³atoms
we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number
mole =given number of atoms ÷ 6.022×10²³(Avogadro number)
Substituting the values
mole=1.9x10²³÷ 6.022×10²³
mole = 0.31 mole of sulfur
Mole = given mass÷ Molar mass
Molar mass of sulfur=32g/mol
mass of sulfur =0.31 mole ×32g/mol
mass of sulfur=9.92g
Therefore, the grams of sulfur in 1.9x10²³ atoms of sulfur is 9.92g.

Calculate the pOH and the pH of a 5.0 x 10-2 M solution of NaOH.
Answer:
pOH = 1.3, pH = 12.7
Explanation:
Since NaOH is a strong base, it will completely ionize; further, since it completely ionizes, our hydroxide concentration (a product of the ionization) will be the same as the given concentration of NaOH.
NaOH -> Na⁺ + OH⁻, [OH⁻] = 5.0 x 10^-2 M
pOH is the negative log of the hydroxide concentration, so plug our hydroxide concentration in:
pOH = -log[OH⁻] = -log[5.0 x 10^-2 M] = 1.3
Since pH + pOH = 14, we can plug in pOH and solve for pH:
pH + 1.3 = 14
pH = 14 - 1.3 = 12.7
Thus, our pOH = 1.3 and pH = 12.7.
