Why has the yen weakened so much? Policy Rate Differentials and Trade Deficits

This is because both the dollar is strengthening and the yen is weakening.

[Developmental Biology] Why didn’t the gene relay alone specify the spatial arrangement?

Although cells have the same blueprint (i.e. genome sequence), the actual human body that is created is not the same.
