In which series are the stages of interphase in the correct order?
g1 phase, g2 phase, s phase
g2 phase, g1 phase, s phase
g0 phase, s phase, g2 phase
g1 phase, s phase, g2 phase

Option D, G1 phase, S phase, G2 phase

Explanation:

The interphase consists of 3 stages –

a)G1 Stage – This stage marks the beginning of interphase. This is basically the prepatory stage in which the cell metabolism is activated and the cell synthesizes proteins required for cell division  before starting replication.

b)S Phase – In this phase , the DNA replication takes place and at the end of this phase chromosomes have two chromatids.  

c)G2 Phase – This phase comes after the S phase. It is also a growth period and no actual cell division takes place in this. Cell synthesizes some more essential proteins. required for cell division.

Thus, the option D is correct.

the speed increase from w to x due to increased gravity force

the speed decreases from x to y due to decrease in gravity
