You decide to repeat the meselson-stahl experiment, except this time you plan to grow the e. coli cells on light 14n medium for many generations and then transfer them to heavy 15n medium and allow them to grow. if the semiconservative model of dna replication is correct, what is the expected distribution of dna in the density gradient after one round of replication

on island x the species needed to adapt because they were being subject to predators which didn't inhabit island y.  

the apgar score is 6

all pink - 2 points

heartbeat

absent - 0 points
