For this circuit, kirchhoff's loop rule gives ir+ldidt=0. note that didt< 0, since the current is decreasing. use this equation to obtain an expression for i(t). express your answer in terms of e, l, and r. use exp(x) for ex.

One answer could be erosion

The fertilized egg  begins to develop into a hollow ball of cells called the blastocyst. 

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
