Answer is the ovary

Explanation: the process by which egg is produced is called oogenesis. It involves the mitotic division of the primodial germ cells to from a oogonia. The oogonia becomes enveloped by follicle cells . Oogonia grows to become the primary oocyte. Each primary oocyte is diploid. It then undergoes the first meiotic division to form the secondary oogonia and a smaller polar nody. all this process of development occurs in the ovary.

After it is released from the ovary, fertilization occurs and it undergoes the second meiotic division to from a polar body and an ovum.

The primary oocyte however remains in prophase of meiosis l throughout childhood.

Write 3 paragraphs on the similarities and differences between the soils, and why each is important. Be as detailed as possible.
lana [24]

Answer:

Ox so it was cheese doodles night...She looked at her little girl who was about to become a teen. She tried to think back to when the girl had been younger but failed to pinpoint the exact moment when she had become a little too big to pick up and carry. It hit her all at once. She was no longer a little girl and she stood there speechless with fear, sadness, and pride all running through her at the same time.

The computer wouldn't start. She banged on the side and tried again. Nothing. She lifted it up and dropped it to the table. Still nothing. She banged her closed fist against the top. It was at this moment she saw the irony of trying to fix the machine with violence.

The trees, therefore, must be such old and primitive techniques that they thought nothing of them, deeming them so inconsequential that even savages like us would know of them and not be suspicious. At that, they probably didn't have too much time after they detected us orbiting and intending to land. And if that were true, there could be only one place where their civilization was hidden.
