Answer: According to the law of faunal succession, the fossils that are found at the bottom layer are considered to be the oldest, whereas the fossils that are present on the top layer is the youngest.
From the given question, the sable antelope is the youngest, and blue antelope is the oldest. This could suggest that the blue antelopes have undergone evolution and with time, they transformed into the horse, which were found to be present in the middle layer as an evidence. And this animal has further undergone evolution and formed the sable antelopes.
Answer:
10g/cm^3, I think.
Explanation:
2x2x2=8cm^3 for the volume.
Divide 80g by that, you get 10g/cm^3, I think.

Answer:
The answer to your question is below
Explanation:
1.-
a) Look for the mass number of Gold in the periodic table
Mass number = 197 g
Use proportions to answer this question
197 g of gold ------------- 6.023 x 10 ²³ atoms
4.64 g of gold ---------- x
x = (4.64 x 6.023 x 10²³) / 197
x = 1.42 x 10²² atoms
2.- mass of 4.12 x 10²⁴ molecules of glucose
Molecular mass = (6 x 12) + (12 X 1) + (6 x 16)
= 72 + 12 + 96
= 180 g
180 g of glucose ------------------- 6.023 x 10 ²³ molecules
x ------------------- 4.12 x 10 ²⁴ molecules
x = (4.12 x 10²⁴ x 180) / 6.023 x 10²³
x = 1231.3 g of glucose
