Control variables why must you use the same number of beads when you construct the second chromosome in step 1?

if u dont u wont get the right answer u always u the same beads u used before but if ur doing somthing else like the vibration with more beads added then u add more beads

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
