Amazing Biology Facts You Must Know About

Biology represents life and life represents the planet. The biological planet is so vast and widespread that many things remain unknown to us throughout the whole life. From this issue and onwards we shall deliver you some amazing biology facts that will make your jaw drop!

So let’s see what are the facts listed here in the current issue.


1. Left Side of the Brain Controls Right Side of the Body


Amazing Biology Facts You Must Know About 1 - Brain

The left cerebral hemisphere of the brain controls the movement of the right side of the body and vice-versa. This is because neural crossings between left and right wiring are known as decussation, occurs just before the junction between the medulla oblongata and the spinal cord.

This is the reason, a stroke affecting the right cerebral hemisphere may result in functional loss or motor skill impairment of the left side of the body (depending on the severity). The decussation of the pyramidal fibres are most probably the byproduct of a much larger evolutionary change: the switch from having a ventral nerve cord of lower organisms to a dorsal nerve cord of higher organisms.


2. Polar Bear has Black Skin and Transparent Fur


Amazing Biology Facts You Must Know About 2 - Polar Bear

Black skin is caused by the presence of high concentration of the pigment eumelanin, which adaptively help them to maximise heat absorption and retention. The hair of polar bear is actually transparent with hollow shaft.

The air spaces in each hair scatter light of all colors as a result we see the white colour. Much like ice, this reflection allows polar bears to appear white. Though thinner hairs underlying the outer coarse guard hairs are not hollow. In a warmer environment (like in zoo), algae grow inside these tiny hollow hairs and hairs appear greenish.

3. The Human Stomach can Dissolve Razor Blades


Amazing Biology Facts You Must Know About 3 - Blade and stomach

On the rare occasion if you swallow a razor blade and if it luckily makes no harm to your ingestion tract during peristalsis, then don’t worry! Inside the stomach, a single-edged blade will dissolve after two hours by the stomach acid. The pH level of human stomach acid is typically 1.0 to 2.0, which means it has a strong pH.

By the way, no need to try this at home because before reaching the stomach it’ll probably harm your ingestion tract unless you are a crazy magician.

The fact has been introduced to make you worry-free if you swallow a razor blade accidentally (though the doctor’s suggestion shouldn’t be ignored).


4. Human DNA can reach the Sun more than 100 times


Amazing Biology Facts You Must Know About 4 - DNA

The male nuclear diploid genome of a single cell extends for 205.00 cm whereas the female value is 208.23 cm, for longer X-chromosome. On average, there are about 10 trillion cells present in the human body. If all of that DNA were lined up, it would cover the distance between the Earth and the Sun more than 100 times.

Aren’t these amazing biology facts! It’s really incredible that our body stores such a lengthy rope!


5. Baby Elephant have to Sit to Drink Water


Amazing Biology Facts You Must Know About 5 - Baby Elephant

Adult elephants drink water through their trunk, but their babies don’t. Baby elephants drink water through their mouth and have to sit to reach the water (alternatively their moms help them). At about one year of age, a baby elephant starts learning how to use its trunk for eating and drinking.

Nature is beautiful, and so is its facts 💚

6. Do you know Bananas are Radioactive?


Amazing Biology Facts You Must Know About 6 - Bananna

Oh my goodness! I eat two bananas daily!

Bananas contain potassium, and since potassium decays, that makes them slightly radioactive. But you don’t need to worry about it because you need to eat about 1 crore bananas at once to die of radiation poisoning.

So, just feel safe because luckily you didn’t get such a big stomach!


7. If You have Cat Bones, You can Jump from 3 Storied Building


Amazing Biology Facts You Must Know About 7 - Cat Bone

Cats are essentially arboreal animals: when they are not living in urban alleys, they live in trees. If slipped from high, they are able to twist their bodies to position their feet under it. Cats can also spread their legs out, increase surface area to create a parachute effect! When they do land, cats’ muscular legs and angular bone joints contribute to the reduction and transfer of mechanical energy.

Unlike human arms, cats’ forelimbs are attached to the shoulder by free-floating clavicle bones, which allow them to squeeze through narrow space and act as the main first shock absorbers while landing. Literally,  they can survive even if they jump from the height of a three-storied building.

8. Only One Type of Mammal can Fly


Amazing Biology Facts You Must Know About 8 - Bat fact

It’s a light one! You probably know the answer.

Maybe you can’t remember at this moment.

It’s the bat. Bats have wings and they can fly. Flying squirrels are another uncommon species that can jump from high and glide but they can’t truly fly like bats.

9. Where Babies beat Adults!


Amazing Biology Facts You Must Know About 9 - Baby

It’s about the human bones. A baby has more bones than an adult!

Babies have about 300 bones at birth. Some of the bones are entirely made of cartilage. This extra flexibility helps them to pass through the birth canal and allows for rapid growth. With age, many of the bones fuse, leaving 206 bones that make up an adult human skeleton.


10. Kidneys are Pretty Hard Workers!


Amazing Biology Facts You Must Know About 10 - Kidney fact

In 24 hours, kidneys filter around 40 gallons of blood. Interesting!

Two kidneys filter around 150- 170 liters of blood per day and roughly produce 1.5 liters of urine, rest volume is reabsorbed by the kidneys. Isn’t this surprising!

On average, an adult has 3 to 4 liters of blood in the body, which means kidneys filter the total blood volume around 40 times per day. Really, how efficient filters are the kidneys!
