Answer:The image to this question is attached.

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.

A red blood cell has been placed into three different solutions. One solution is isotonic to the cell, one solution is hypotonic
Dmitry [639]

The type of solution in each beaker based on cell's reaction are :

  • Isotonic solution : Normal reaction
  • Hypotonic solution : The cell becomes turgid
  • Hypertonic solution : The cell becomes deformed

<h3>Matching each solution to the cell reaction </h3>

When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.

Hence we can conclude that The type of solution in each beaker based on cell's reaction are : Isotonic solution : Normal reaction, Hypotonic solution : The cell becomes turgid, Hypertonic solution : The cell becomes deformed
