Mimosa pudica bends upon being touched. This occurs due to changes in the turgor pressure in its cells. The behavior is a predator avoidance mechanism.

Mimosa pudica is a perennial herb of the Fabaceae pea family, native to Central and South America. Commonly called the touch-me-not plant, the sensitive plant, or the ‘Tickle Me plant’, it is known for closing its leaves or folding them inwards when touched.

These are called nastic movements – movements that occur in response to a stimulus. If the stimulus is a touch or contact stimulus such as the wind, they are called seismonastic movements or thigmonasty. If the stimulus is heat, they are called thermonastic movements. If they are light reactions, the movements are photonastic, while day and night-based movements are called nyctinastic movements.

Mimosa pudica not only responds to seismonastic movements; it also closes upon being heated. When the plant is exposed to such stimuli, it undergoes a series of biochemical and bioelectrical changes that allow it to bend inwards.

Why Do Touch-Me-Not (Mimosa Pudica) Leaves Close When Touched?

The outcome of a fight between lion and tiger would depend heavily on the individuals–their age, breed, mood, fighting style, and physiology. However, historical evidence suggests that tigers are a bit more likely to win the duel.

When it comes to animals in the wild, lions and tigers are two of the most intimidating predators on the planet. They are infamous for preying even on humans, so before we get into the captivating rivalry of these two super cats, let’s take a look at them individually.

Both cats have their own advantages and limitations. So the tiger, for example, is a lone hunter for most of its life and has more muscle mass. They are bigger and heavier in weight. In addition, they have sharper and longer fangs and claws. A tiger is slightly faster, arguably more ferocious, and definitely more agile. It can swim in the water and climb trees. Lions, on the other hand, are more resilient and brave. They have experience putting down large enemies—as big as an elephant or a giraffe—albeit in a group. Lions also have experience combatting other lions in the wild to defend their pride, something tigers lack.

Tigers are fierce predators, play it safe and quickly launch powerful attacks on their opponents. Lions first measure the strength of the opponent by striking with a single paw in duels. They usually take a little more time to go all out on the opponent. Perhaps this is because they generally have other lions as backups in the wild. Tigers are impulsive attackers who want to go all out from the beginning. Perhaps evolution has conditioned them to be more ferocious and always rely on the quick kill. Sometimes this can backfire, as a tiger could lose energy faster, and if it encounters a resilient lion, the tiger could fall victim to the lion!

Although it is not clear who the winner will be, tigers appear to be serious contenders for the King of Jungle, a designation usually reserved for lions!

Lion vs Tiger: Which Would Win In A Fight?

ScienceABC II 92 views January 8, 2022 7:43 am

Most of Humanity is in India and China because the ratio of human survival and occupation of the planet has always been similar, but modern advancements have allowed those numbers to increase exponentially, so the difference has become more obvious.


After the initial spread of humanity from Africa, China and India proved to be two of the most hospitable places for hunting, gathering, agriculture, and survival, mainly due to climatic conditions and available crop selection.

With more availability for agriculture and healthy life, survival rates were higher, while more space and food meant that more babies could be born.

1,000 years ago, Asia definitely had more people, but there were only about a hundred million more than people in the rest of the world.

Babies were born all over the world, and mortality rates were relatively similar; many people did not survive even to childbearing age, which "kept the world's population in check." The inability to mass-produce food also made larger populations less viable.

Moreover, it is important to remember that wars and epidemics would have had much longer and larger effects in the past. The number of people was so much smaller, life was so much shorter, and birth conditions were scarce in many parts of the world.

Why Is Most Of Humanity Concentrated In India And China?

Multiverse theory suggests that our universe, which consists of billions and billions of planets, stars and galaxies and extends out tens of billions of light-years, may not be the only universe that exists. There could be another universe that is completely different from ours with its own natural laws. Even more maddeningly, there may not be just one, but an infinite number of such universes, all of which differ from one another and harbor millions of celestial bodies and even intelligent life forms, just as our universe does.

Multiverse theory assumes that our universe is only a small member of an enormous composition of a multitude of universes.

The idea of multiple universes is so astounding that it has been hypothesized not only in cosmology and astronomy, but also in philosophy, music, literature, science fiction, and even religion. Because of the universality of this idea, these “other" universes are called by different names, including parallel universes, alternative universes, parallel realities, quantum realities, alternative realities, and more.
In this video, we explain what exactly is the multiverse theory and what it means for humankind.
