Most of our knowledge about Earth's interior comes from Seismic waves. Thus, option C is correct.
<h3>What is seismic waves</h3>
Seismic waves are created by abrupt movement of elements within the Earth, including fault rupture during an earthquake. Seismic waves can be caused by volcanic eruptions, blasts, landslides, rock slides, and even flowing rivers.
Seismic waves, also known as compressional or longitudinal waves, push and pull the earth in the direction of motion. Seismic waves provide the majority of our information about the Earth's innards. As a result, option C is correct.

Answer:
b. 336,000.
Explanation:
Step 1: Calculate the molecular weight of the monomer
Polyethilene is a polymer with the formula (C₂H₄)ₙ, where C₂H₄ is the monomer and n is the number of monomers in the polymer. We can calculate the molecular weight of the monomer by addition of the weights of the atoms that form it.
MC₂H₄ = 2 × MC + 4 × MH
MC₂H₄ = 2 × 12 + 4 × 1 = 28
Step 2: Calculate the average molecular weight of polyethylene
The average degree of polymerization (DP) of polyethylene is 12,000. We can calculate the average molecular weight of polyethylene using the following expression.
DP = M(C₂H₄)ₙ/MC₂H₄
M(C₂H₄)ₙ = DP × MC₂H₄
M(C₂H₄)ₙ = 12,000 × 28 = 336,000
Answer: They will have different beak pointiness since their proteins for beak pointiness are different so the proteins will connect in different ways.
Explanation:
Based on the information provided in the question, it should be noted that the pointiness of the birds beak will be different as a result the difference of their proteins for beak pointiness so the proteins will connect in different ways.
Assuming the two junco birds have thesame proteins in their cells for beak
pointiness, they'll have thesame beak pointiness.
Answer:
D. Perform a thorough visual inspection.
