After dividing the earthworm into two segments, how many will he divide into one, one or two?

Cutting an earthworm into two pieces does not actually turn into two earthworms. Many people think that if an earthworm is cut in half, it will become two new earthworms, because even after being cut off, the earthworm segments on both sides will continue to writhe, but if you keep observing, you may be disappointed because at most only one of them will survive, and the other end will become a corpse.

When an earthworm is broken in two, the muscles on its section will contract rapidly, and some of the muscles will dissolve on their own, and the white blood cells will be at the same time.

It collects on the cross-section, forming an embolism, which allows the wound to close, and the regenerated cells in the body will quickly transfer to the wound, so that the regenerated cells will follow the dissolved muscle cells on the cross-section.

Together, a new regenerative bud is formed on the cross-section, so that the severed part will grow back.

Because it takes about 7 days for the earthworm to regenerate, after cutting the earthworm in half, the experimenters specially found a simulated normal natural environment.

Seven days later, it was found that the earthworms that had been cut in half had indeed regenerated into two earthworms.

In the second experiment, the earthworm was cut off from three-quarters of the body, and after seven days under the same conditions, it was found that the earthworm with most of the body had successfully regenerated, while the remaining quarter of the body-length earthworm had dried up.

Theoretically, the two sections of earthworms that have been cut open will not both survive, and there will be no father-son, husband and wife, or brother-brother relationship. Even if it really works, it should theoretically be a brotherhood!

There are thousands of species on the earth, and there are indeed creatures that are more capable of surviving than earthworms, such as planarians.

Scientific studies have shown that even if planarians are cut into 300 segments, each segment can still grow into a new individual, and I have to sigh that the survival ability is too strong, and the planarians can still grow heads after survival. In this way, it seems that each new individual should be equal and can be seen as a "brother"!

After surviving, the two earthworms have nothing to do with each other, they have become independent individuals, with their own corresponding abilities, and there is no connection between them.

After surviving, these two earthworms should have the most intimate relationship, and their genes are the same, because they are originally an earthworm.

Because the earthworm's ability to live is very strong, in fact, it is also because each cell of the earthworm's body is independent.

It's a strange worm relationship. Because it's close in front of you, you can't go back to the past. The mode of movement is peristaltic contraction. Several somites form a group, one group of medial longitudinal muscles contract, the ring muscles relax, and the somites shorten, while pressure in the body cavity increases, and bristles stick out to attach.

In the adjacent somite group, the annular muscle contractions, the longitudinal muscle relaxes, the somites lengthen, the pressure in the body cavity decreases, and the bristles are retracted. Each somite group alternately contracts the longitudinal and annular muscles with the adjacent somite group, causing the body to move forward in waves. The earthworm can advance 2-3 cm with each contraction, and the direction of contraction can be reversed, so it can do backward movements.

Divide an earthworm into nine segments, and when they grow into nine earthworms, what is their relationship?

This is the earthworm doppelganger, which is annelids that reproduce rapidly after cutting, regrowing their heads and tails to form new earthworms.

Independent relationship, you have my smell in you.

The art of multiple shadow clones!
