Answer:
Ancient landmasses
Explanation:
The same fossils being found in widely separate areas can help scientists infer the geography of the continents of that time.
For example: Africa and South America used to be connected during the Permian Period.
Scientists can confirm this because both continents are home to similar fossils.
Genotype frequency: RR is dominant, Rr is heterozygous and rr is recessive.
R^2+2Rr+r^2 = 1
R = 0.85
R^2= 0.85*0.85 = 0.7225
B: They occur more quickly than reactions without enzymes
