How many neutrons does element x have if it’s atomic number is 22 and it’s mass number is 75?

Chem was fun last year XD

Anyway..

To find how many neutrons are in element x:

We take the mass number and subtract it with the atomic number

So, 75-22=53 neutrons...BOOM! :D

g1

choices:

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
