Dependant variables are the variables we are testing and that are not changing in intervals (well it can but sometimes)
Independant variables are the variables that are not effected. For example, time. Time is usually measured in intervals
Controlled variable is the one which we are keeping constant. For example, while measuring resistance in a wire, we keep the temp. constant

You circle any cell that has two chromosomes at the edges for (i). For (ii) it is mitosis as this is not a process involved in the creation of gametes(in that case it would be meiosis). :D
