Why do living things die??? Why do living things die?

To live better! If people don't die, then you don't even have a place to stand If people don't die, then there will be more and more people, and the earth will not be able to live!! What is the origin of man?

Australopithecus What about Australopithecus? ...The earliest is the single-celled class Single-celled organisms are so low-level, so they have to rely on reproduction and mutation to achieve the purpose of existence I think: Human beings are still low-level creatures When human beings reproduce for x years, and high-level species appear, they can not die without relying on reproduction and mutation to achieve the purpose of existence Attention questioner:

And that's where the theory comes in, but I'm sorry, but I added that single-celled species only live for tens of minutes to hours, and some plants only live for a few hours to a few days ......Some animals can live for a few years to a dozen years, but humans can live for about 100 years, and that's the difference between lower and higher organisms.

Because all living things are made up of cells, cells can only be renewed for 50-60 generations, except for cancer cells, which are mutated, immortal, and infinitely proliferated.

Here's my own, I don't know if it's right ......Organisms die because of cellular senescence, and scientists have put forward many hypotheses about cellular senescence, and the free radical theory and telomere theory are generally accepted.

nutricula), most likely the only creature in the world that does not die.

According to scientists, the diameter of the "lighthouse jellyfish" is only 4 5 millimeters, but it is such a very tiny creature that has a magical ability to "rejuvenate". According to reports, normally, jellyfish will die after reproducing the next generation, but after the "lighthouse jellyfish" reach the stage of sexual maturity, they will return to the young stage and start another life process, and theoretically, this cycle process is repeated again and again and can be repeated forever.

Why do all living things die? Who is behind the scenes? Or it in the universe.

The following part is mine.

Bai conjecture, only to do du reference, dead.

The reason is not that the gene control system actively destroys cells, but prevents the body's self-contouring and rejuvenation, the number of stem cells decreases, and the aging of a single cell leads to the aging of the individual as a whole, and eventually dies of inflammation and other diseases, which is the outcome of the life of most animals and plants (except for ** food), it is true that for the population, the existence of individual birth, aging, sickness and death is beneficial to evolution, but people live in the group as individuals, and the tradition of relying on the population to reproduce is outdated, It is neither the death gene nor the war disease that threatens people's lives, but the increasingly harsh environment and the decline of the maximum carrying capacity.

The longest-lived creature in the world, with an "immortal body", can also "rejuvenate"!

After death, all living things decay, are broken down by microorganisms, become inorganic, and return to nature in another form. As for whether there is a soul and an underworld, this kind of thing has not been confirmed, so only after the death of the person himself will know whether there is one.

I think that when we die, they will all become our dirt, so I think this is also a very strange thing, so we should pray for them.

After death, living organisms will naturally decay, will turn into humus, and then will turn into water, various organic matter and organic salts.

After death, living beings will become micromolecules, which can be used as nourishment for mud, and life and death are like a reincarnation.

When a creature dies, it becomes an organic substance, which then provides energy to other living beings.

There should be very few creatures that will never die, because all of his creatures have a lifespan, and after that period of time, then it is easy for him to survive, unless he raises his offspring and allows his offspring to multiply from generation to generation.

There is no creature on earth that will never die. But there are a handful of creatures that can live forever. For example, lighthouse jellyfish.

All living things in the world are made up of cells, and cells are very important because they store a lot of information about their operations. Some cells recover if they are damaged, but others do not, such as brain cells; When cells are no longer able to reorganize, the organs to which they belong will gradually lose their function. In this case, the body will not function properly and its functions will slowly decline and die.

There are two main causes of human death: disease and degeneration. External factors such as bacteria can damage the cells in the human body, and if the cells do not recover, that part of the organ begins to lose its function (each organ in the body has its own unique function), which will affect the normal functioning of the whole body.

If the body doesn't function properly, we die.

Another factor is cell degeneration, a phenomenon in which each cell knows how long they live, a phenomenon known as programming

death, when a cell has been working for a period of time, the cell begins to fatigue, decay, and even die. At this time, the organs slowly lose their function, so that we degenerate and die.

In fact, any living thing in the world will die, but there are different lifespans, some are as short as a day or two, and some can be as long as hundreds of years, but.

Eventually, they will all die.
