When the dna begin to coil and condense, the cell is in g0 phase g1 phase g2 phase s phase

Correct C) G2 phase

G2 phase is the final sub-phase of interphase of the cell cycle. G2 phase ends with the onset of prophase, it is the phase in which cell chromatin condense and coil up in order to form chromosomes.  

It allows DNA to wrap more tightly and take less space inside the cell. The DNA condense further by the histone protein, it helps in the formation of tightly wrapped and condensed set of chromosomes.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
