Answer:
"Subsoil" is the correct answer.
Explanation:
- The method of transforming sediments become rocky solids is considered as Lithification. The floor stratum or level below the upper floors at the base of the floor is a Subsoil.
- Sediments comprise materials particles like sand, pebbles, skeletons kind of bones as well as muck, that were transported and produced instead in water or perhaps wind someplace.

Biosphere
Explanation:
The biosphere is the area of Earth where living things exist. The biosphere is divided into regions known as biomes. In general, biomes are areas with a particular type of climate and similar plant and animal species.
Answer:
Mass = 1274 .64 g it would be option C if it is converted into kilogram
1274 .64 / 1000 = 1.27 Kg
Explanation:
Given data:
Number of moles of C₂₀H₄₂ = 4.52 mol
Molar mass of carbon = 12 g/mol
Molar mass of hydrogen = 1.0 g/mol
Mass of C₂₀H₄₂ = ?
Solution:
Number of moles = mass / molar mass
Molar mass = 20× 12 + 42× 1.0 = 282 g/mol
Now we will put the values in formula:
Number of moles = mass / molar mass
4.52 mol = mass / 282 g /mol
Mass = 4.52 mol × 282 g/mol
Mass = 1274 .64 g
Each of the Nitrogen atoms has 2 non bonded valence electrons, meaning that there are 4 pairs total.
