During the nineteenth century, biologists knew that South America and Africa contained similar fossils. These fossils led them t
o believe that a temporary land bridge between South America and Africa allowed ancient species to move between both continents. In the twentieth century, evidence showed that South America and Africa were once part of the same larger continent and that there were no land bridges
between them. How should biologists respond to the new geological finding?
A) Biologists should reject the geological finding, because it is new.
B) Biologists should ask physicists what to do, because physics is a more exact science.
C) Biologists should reject the belief in ancient species, because there were no land bridges.
D) Biologists should update the history of life, because it should include the new geological finding.
Carbon molar mass=12 carbon mass in the above question =6 mole=number of atoms/6.02x10²³ 6/12= number of atoms/6.02x10²³ number of atoms=1/2 x6.02x10²³ number of atoms= 6.02 x10²³/2 number of atoms=3.01x10²³
