It is either Slate, Phyllite, Schist, and or Gneiss
Answer:
1.7700×10^-22 g
Explanation:
A face-centered-cubic cell contains 4 atoms, so the volume per atom is ...
(389.80×10^-12 m)³/(4 atoms) ≈ 1.4725×10^-29 m³
Then the mass of 1 atom is ...
(12020 kg/m³)(1.4725×10^-29 m³) ≈ 1.76995×10^-25 kg
≈ 1.7700×10^-22 g
_____
<em>Additional comment</em>
That is the approximate mass of a Palladium atom.
I don't know much about this, but probably the reason why your teacher circled 300k is because of what's in the photo below. If you couldn't tell from the photo, its because 300k isn't negative. Anyway this is my guess, based on my limited knowledge.

Answer:
while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules can be used to determine species' relatedness.
