Why do earthworms survive 40 if they are cut in two

You have such a high bounty, how can you ask this question, is it strange,,, what is the problem,,, let me think about it,,, don't worry, I'll figure it out right away.

Under normal circumstances, it depends on the position of the truncation, which can be stocked in three sections, but it depends on whether the position of the truncation is between five and eight sections, this position is the easiest to survive, and four sections are also possible, but not necessarily every section can survive.

No. Experiments have shown that earthworms do not die when cut in two, and they slowly grow into two separate individuals.

Definitely, because the body is no longer complete, so all the functions cannot be used.

Cut the earthworm in half, the earthworm will not die, because the earthworm has the ability to regenerate. The part that was chopped off. It can continue to grow into a complete earthworm.

Cutting the earthworm in two will not die, because the internal structure of the earthworm is repeated and repeated, and separating the repeated parts can reorganize the cells in the blood, so that the wound closes quickly and forms a new cell mass.

If an earthworm is cut in two, it will generally not die if it does not harm its vital organs. Because the internal structure of the earthworm is repetitive.

If an earthworm is cut in two, it will not die as long as the environment and temperature are suitable, but will become two earthworms after dozens of days of growth.

If the earthworm is cut into two sections, the muscle tissue on the section will immediately strengthen the contraction, and a part of the muscle tissue will quickly dissolve 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 mesodermal cells are very strong.

However, the regeneration ability of earthworms in different body segments is different, and the regeneration rate of body segments without head and tail is faster than that of body segments without heads and tails. Among them, the head and tail of the headless and tailless earthworm body segment can be regenerated, but the regeneration rate of the tail is significantly higher than that of the head. The number of earthworm segments left after shearing has a great impact on the survival rate of earthworms.

The higher the number of segments remaining, the lower the mortality rate of earthworm segments, and there was a positive correlation between the two.

Planarians have a lot of undifferentiated, embryonic cells in their heads and coelenterates, which may be the reason for the strong regenerative capacity of the head. The regeneration ability of the earthworm's head is also stronger than that of the rear segment of the body, and if the earthworm is cut into two sections and the abdominal nerve is removed, the earthworm loses its ability to regenerate. These experiments show that nerves play an important role in regeneration.

Earthworms don't die when cut in two; Earthworms are a special type of reliant animal. If an earthworm is cut in two pieces in the middle, it will not die, but will instead become two complete worms.

When it is cut into two sections, the muscle tissue on its section immediately strengthens the contraction, and a part of the muscle cells quickly dissolves to form a new cell mass, and the blood cells in the blood are focused on the cut surface at the same time, forming a special embolism, so that the wound is quickly closed.
