When an earthworm is broken in two, it can become two earthworms.
First, the muscle tissue on the cut surface will contract immediately, and a part of the muscle will quickly dissolve by itself to form a new cell mass. White blood cells will also condense on the cut surface to form an embolism, so that the wound on the cut surface will be closed quickly, preventing blood loss and tissue fluid loss. Resist microbial invasion.
After the closed body cavity is re-formed in this way, the earthworm can survive, which is the stage of regeneration.
At present, the mechanism of earthworm regeneration is still unclear, and there are two main hypotheses.
One is that after the body cavity is closed, the primary cells in the compartment of the body cavity will quickly move to the section and form nodular regenerative buds together with the muscle cells that dissolve themselves. At the same time, a large number of mitosis is carried out in the body, and the cells of the digestive tract, nervous system, blood vessels and other tissues grow rapidly to the regeneration bud site.
The second is that the cells in the section will dedifferentiate and return to the original undifferentiated state, and then these cells will divide, differentiate, grow and regenerate.
Both hypotheses lead to the same result.
In this way, a new head will grow on the section without the head; a new tail will grow on the section without the tail.
One earthworm becomes two complete earthworms.
Earthworms are also a kind of life.
Is this leg of lamb still alive
When Gu Jun heard Wu Shiyu's words, the first reaction in his mind was to think of earthworms, and then he looked at the giant broken leg of lamb in front of him, as if he could clearly see the subcutaneous tissue of its thigh melting itself.
It is different from earthworms, its biological mechanism is more complex than earthworms,
When the liquid escaped, it recondensed, and after a regeneration process, it became another black goat cub.
These thoughts flashed through almost instantly, and Gu Jun's head ached even more violently, and the sense of phantoms intensified.
But at the same time, in the investigation ability column of the new system panel, the experience of anatomy has also increased.
[You have improved your understanding of life by observing black goat cubs, +200 experience points, 4700/5000 (level 1/level 9)]
Gu Jun was a little surprised that this can also increase experience, but the introduction to anatomy has already said that the purpose of anatomy is to understand the mysteries of life through anatomy. Summarizing is an effective method.
"I can feel the stick insect." Wu Shiyu quickly walked to the side, "It must be pretending to be dead."
Stick insects have the ability to regenerate severed limbs.
"Earthworm." Gu Jun also said his thoughts, "I suspect that it is dissolving itself and preparing for regeneration."
Hearing what the two of them said, Wang Ruoxiang, Uncle Dan, Xiao Huiwen and the others all came to a realization, and dissolved themselves? regeneration? Wang Ruoxiang quickly asked: "Gu Jun, should we get out of the car immediately, turn on the freezer, and freeze it completely first."
Now there are two crises, one is to be slipped away by those liquids, but this is not an urgent matter, because this carriage is airtight, and every drop of liquid from the leg of lamb has been put into the isolation bucket. What is urgent is another crisis. If this continues, the leg of lamb will completely dissolve.
What Wang Ruoxiang said is a solution, but can freezing really stop it
Water begins to freeze at zero degrees Celsius, but the tissue fluid of insects can withstand low temperatures below zero degrees Celsius without freezing, which is called "supercooling".
There are also cell activities. Freezing cannot completely stop the cell activities of some ordinary life forms, but this is still an abnormal life...
"You try to freeze some liquid first! See if there is any overcooling phenomenon." Gu Jun said, while his mind turned, looking at the column "4650/5000 (level 1/level 9)" in his mind, it was almost It can be upgraded, and there may be rewards after the upgrade...
There is still 300 experience left, facing a new kind of alien, and there is still a chance to improve before going deep into the local solution.
While Wang Ruoxiang and Uncle Dan were moving, he looked thoughtfully at the liquid that had dyed the drainage tube dark green, and it was still flowing.
The human body naturally also has a lot of fluid. In fact, about 60% of each person's body weight is body fluid, which is divided into two parts, accounting for about two-thirds of the intracellular fluid and about one-third of the extracellular fluid. Interstitial fluid, which belongs to extracellular fluid, can account for about 16% of body weight.
This concept belongs to the category of physiology.
Because anatomy is mostly about figuring out the hierarchy of a biological body.
But what about anatomy in a broad sense, what if black goat calves had different body shapes
"This is not some kind of dirty liquid..." Gu Jun murmured thinking, and reached out his hand to get a little dark green liquid on the leg of the lamb. Even through the protective clothing, he seemed to feel its stickiness and heat, "This is the young black goat." The cub's interstitial fluid, probably all over its body..."
Xiao Huiwen on the communication screen asked in surprise: "You mean it can dissolve itself and transform into a liquid to achieve regeneration?"
"Imagination, a hypothesis." Gu Jun picked up the Kalop scalpel in his hand, stabbed it violently into the shriveled skin of the thigh of the leg of lamb, and cut it with gritted teeth, "This liquid can make it growth, but also to repair its damage, as well as metamorphosis and regeneration...”
Only species with such abilities can be called having strong fecundity, insect-like ability, and insect-like fecundity.
Not easily killed, death is only the beginning of rebirth.
One descendant is thousands of descendants.
Chi! Gu Jun cut open a small piece of skin of the leg of lamb, and when he lifted it, he saw that the shriveled inside was tattered and fuzzy. Some were dark green liquid, and some were dark red liquid that was dissolving from the flesh and blood, and then turned dark green...
"It can change." He murmured, "Its structure can also change."
On the other side, Wang Ruoxiang collected a small cup of abnormal fluid and put it into a -20c freezer.
However, looking at the foreign liquid in the box after a while, Gu Jun guessed it right. The foreign liquid in the measuring cup showed no sign of freezing at all!
And the dark green liquid seemed to be stirring slowly, as if it was alive.
The anatomy experts were stunned, Xiao Huiwen asked anxiously: "Then how to stop it? We still have to study this form..."
"Yes, yes!" Ji Li repeatedly patted his thighs and gestured, "You must stop!"
Gu Jun looked at the cup of foreign liquid that did not freeze, thinking that it had really cooled down...
Suddenly at this time, he only felt refreshed in his mind, and the anatomy completion rate of the task increased to 0.51%, and several messages popped up one after another:
[You have improved your understanding of life by observing black goat cubs, +300 experience points, 5000/5000 (level 1/level 9)]
