Oogonia multiply until the fifth month .within six months after birth ,each will transform into a primary oocyte .
What is oogonia ?
During foetal stag of development the embryo develops the germinal epithelium of ovary .some of the cells of germinal epithelium enlarge and divide mitotically . the dividing cells projects into the stroma as a cord known as the egg tube of Pflugar;which later becomes a round mass ,called the egg nest .all these dividing cells are egg mother cells known as Oogonia.this is derived from the endodermal lining of the embryonic yolk sac which comes to lie in the ovary of the female ( while it is still an embryo ).
What is primary oocyte?
One cell of the egg nest grows but does not divide furter so as to form the primary oocyte.the primary oocyte is diploid and enters the growth phase.it is dormant stage ,nucleus intact ,female is born with these in her ovary.every month primary oocytes resume oogenesis and start developing growth and development in the onset of puberty.
Hence the correct answer is Primary oocyte.

Answer:
yes that's correct but what are we answering then?
Explanation:
Answer:
Appropriate Question:-
The output for a 60kg woman who runs up a 3m high flight of stairs in 3.5 sec.starting from rest but having a final speed of 2 m/s.
Given:-
Mass of woman=m=60kg.
Height=h=3m
Time=t=3.5secs.
To find :-
Here we want to calculate the output for a woman
Here first we should calculate work done first.
work \: done = mghworkdone=mgh
Applying the values,
work \: done = 10 \times 60 \times 3workdone=10×60×3
Work done= 1800Joule.
Now , lets calculate power,
power = \frac{workdone}{time \: taken} power=
timetaken
workdone
Now,
Applying the values ,
power = \frac{1800}{3.5} power=
3.5
1800
Power =514.2857 watt.
Hope it helps u mate .
Thank you .
