(D)All of the above are possible.
Explanation:
According to the rock cycle, all of the transitions given are possible with several unlimited steps.
The rock cycle shows how the different rock types are transformed from one form to another.
In the rock cycle the major rock types are taken into consideration. These rock types are Igneous, sedimentary and metamorphic.
- An intrusive igneous rock becomes a sedimentary rock.
Based on the rock cycle, an intrusive rock can become a sedimentary rock. This is igneous to sedimentary rock conversion. Here, the intrusive rock is brought during a terrain change to the surface. Weathering, erosion, transportation and deposition combines to produce sediments and take them to their basin of deposition where they form sedimentary rocks.
- A sedimentary rock becomes soil.
By weathering, a sedimentary rock can be come a soil. Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soil.
- A metamorphic rock becomes an extrusive igneous rock.
When metamorphic rocks are subjected to intense heat and pressure, they reach their melting point.
As they melt, they produce magma which can be brought to the surface to form extrusive volcanic rocks.

D because B is silly, yes we are in groups but that is not how we are put together, Same for reproduction. That is how you're made.
Answer:
the value of Kp at 25°C is 2.37 × 10⁻⁴atm³
Explanation:
Given that Kp = 0.116atm
NH₄(NH₂CO₂)(s) ⇄ 2NH₃(g) + CO₂(g)
2x atm xatm
Pt = PNH₃ PCO₂
0.116 = 2x + x
0.116 = 3x
x = 0.116/3
x = 0.039 atm
PNH₃ = 2x =2(0.039) = 0.078 atm
PCO₂ = x = 0.039 atm
Now,
KP = PNH₃² × PCO₂
= 0.078² × 0.039 atm³
= 2.37 × 10⁻⁴ atm³
the value of Kp at 25°C is 2.37 × 10⁻⁴atm³
Freshwater ecosystem type is the factor that does not determine the strength of a toxic in an aquatic ecosystem.
- A toxin is a substance which is responsible for causing detrimental effects on the body of the living organisms.
- The excess dose of toxin can produce lethal effects in living beings.
- The strength of the toxin is determined by its amount or concentration in the water body more the amount or concentration of toxin the more will be its strength.
- The strength of toxin can be determined by its absorption in the aquatic organisms like gills of fishes more the absorption more will be the strength and more will be the impact.
- The strength of toxin can also be determined by the mutation it can cause more the number of mutation it can cause more lethal will be the effect.
- The freshwater ecosystem is a source of freshwater which will be free from saline water. It can be a river, lake, pond, or others.
- It does not matter which type of freshwater ecosystem is affected by the toxin. If the toxin is able to mix with the water then it can be absorbed by the aquatic organisms and the toxin will exert its negative effects.
- Hence, freshwater ecosystem type is the correct option.
