What happens when the earthworm is halved into two

The earthworm is not cut into two parts, and both parts can live, but after being cut into two parts, the one with the head can live, and after regeneration, it becomes a complete earthworm, and the other part dies.

The earthworm is cut in half, and instead of dying, the earthworm will grow into two.

Turning into two earthworms, it is very self-sufficient.

If an earthworm is cut in half, can it become two beings? You can't think of the answer!

It depends on the situation, although earthworms have the ability to regenerate, there are thousands of earthworm species in the world, and the regeneration ability of different species of earthworms is also very different. On the earthworm's body, near the head, there is a reproductive ring, and only a section containing the reproductive ring can grow a new body segment and become a complete individual.

An earthworm has 150 rings and vital organs are in 11-40 nodes, if cut on 11-40 nodes, damage the vital organs, then the earthworm can not survive, if cut in other positions can be regenerated.

When the earthworm is cut into two sections, the muscle tissue on its section immediately contracts, and a part of the muscle quickly dissolves on its own, forming a new cell mass, and at the same time, white blood cells gather on the cut surface, forming an embolism, so that the wound is quickly closed.

The mesoderm cells of the earthworm also have a very strong differentiation ability, and when it is wounded, the undifferentiated original cells that were originally located in the diaphragm in the body cavity quickly move to the wound section and connect with their own dissolved muscle cells.

When the earthworm is truncated, the muscle tissue on the section immediately tightens and contractes, and a part of the muscle tissue quickly dissolves to form a new cell mass. At this time, the white blood cells in the blood collect at the same time on the cut plane, forming a special embolism that allows the wound to close quickly. Its mesoderm cells have a strong ability to differentiate, and when there is a wound, the undifferentiated primary cells that are originally located in the diaphragm of the body cavity quickly move to the wound section, and together with the muscle cells that dissolve themselves, they form nodular bulges on the cut surface, called regenerative buds.

In fact, only half of the head of the earthworm can grow to survive, and the tail part will die. They are inferior animals and do not have complex minds like humans. It's nothing to meet.

It will turn into two earthworms, and if it breaks in the middle, it will die.

Because it has the ability to regenerate, it will become two.
