In fact, it usually takes about ten minutes to boil eggs, and the egg white and yolk are cooked in ten minutes. ?

Eggs must be cooked before eating, but not too long or too short. If cooked for too long, the taste will go bad, and the eggs will be a little old and not very delicious.

Cooking time is too short, which may lead to incomplete cooking and incomplete bacteria removal, so when cooking eggs, be sure to cook them before eating.

Egg formation

When the oocyte grows and develops in the ovary, the yolk substance gradually accumulates and increases in the egg. The yolk substance takes concentric circles as layers, forming a yolk structure in which deep yolk and shallow yolk are alternately arranged. The yolk nucleus consists of white yolk, which extends to the animal pole and slightly expands at the end. The expanded part is called Pan's nucleus.

White egg yolk contains more protein, and yellow egg yolk is rich in fat. There is very little cytoplasm in the egg, which is mainly located in an area at the top of the animal polar yolk, where the nucleus is located. With the increase of yolk substance in oocyte, the volume becomes larger and follicles protrude from the surface of ovary. When ovulating, the primary oocyte completes the first mature division and discharges the first polar body to become the second polar body oocyte.

Then enter the metaphase of meiosis. During ovulation, the theca ruptures, and the secondary oocytes are released from the ovary and immediately participate in the very active oviduct umbrella. Stay in the umbrella for about 15 minutes. If you encounter sperm here, you can complete the fertilization process and discharge the second diode.
