Question 1

A human has 20 million kilometers of dna, that’s enough to go to the moon and come back, so many times

Question 2

“More than 80% of all genetically modified crops grown worldwide have been engineered for herbicide tolerance. As a result, the use of toxic herbicides, such as Roundup, has increased fifteenfold since GMOs were first introduced.”
The evidence continues: GMO crops are also responsible for the emergence of superweed and superbugs that can only be killed with increasingly toxic poisons.

Question 3

Native wit is the intelligence or common sense with which one is normally born.

Question 4

Why do we listen to celebrities ? Why to we trust Shah Rukh Khan when we says Byjus is good, even though we know his education skills are not trustworthy ? Evolutionary reason is that we always want to copy people who survive. People who do well in terms of survivorship, we always want to copy. We dont even chose specific traits fo the person, but copy everything he or she does because survival of the fittest. Its pretty cool !

Question 5

The bubonic plague wiped out around 40% of the worlds population

Question 6

DNA’s objective seems to be to create proteins which are essential to life. But DNA cannot create proteins as proteins do not understand the language of DNA. DNA instead uses RNA to create these proteins. RNA acts as an interpreter between the 2.
When you grow, your DNA replicates when new cells are formed. For replication, it un-stands itself and one strand is used as a template to create another one. If you have one strand, it’s easy to create another one as certain compounds only binds with certain ones. So in a single strand, every A only binds with C, so when you see A in one strand, the other strand needs a C for a binding. 2 humans will have 99.9% of the DNA to be the same.

Question 7

Leopold II and his actions in Belgium is the worst example of colonization. He had the locals go and get rubber (whose price was going up in the industrial revolution) and had daily quotas for them to get. If they didn’t, he would cut their limbs off. When afircan sleeping sickness started in Uganda, Leopold was tensed that it might kill the people of Congo and stop his loot, so he gave out a prize to anyone who could solve this. This gave rise to a lot of tropical diseases being studied and people from here generally joined Jansen pharma (which J&J purchased). Jansen pharma is the one that created the J&J Covid Vaccine.

Question 8

Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.

Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235U) has been increased through the process of isotope separation. Naturally occurring uranium is composed of three major isotopes: uranium-238 (238U with 99.2739–99.2752% natural abundance), uranium-235 (235U, 0.7198–0.7202%), and uranium-234 (234U, 0.0050–0.0059%).[

Question 9

Apollo 11 launched from Cape Kennedy on July 16, 1969, carrying Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin “Buzz” Aldrin into an initial Earth-orbit

Question 10

For the last 10,000 years the climate has stabilized. The average climate diff in the last 10000 years has been between -1 and +1 degree centrage. This is why humanity was able to domesticate wheat, rice and other grains on different continents around the same time. For the first time we have had reliable seasons and that’s why civilizations even started existing. This is called the Holocene epoch.

Question 11

Platypus is an egg laying mammal which nurses their kids using milk

Question 12

The pink thing on the side of your eyes is actually a third eye lid which is vestigial today. It was meant to close from the left to the right. But is not present anymore.

Question 13

Monarch butterfly - They are a black and orange butterfly which travels 3000 miles for migration.

Question 14

Maida is made from wheat. Wheat grain consists of the outer layer called bran and an inside called germ and a predominantly white thing called endosperm. Maida is just the endosperm.

Question 15

You get more drunk on an empty stomach because when you eat, the connector between stomach and intestine closes when your full. So when you eat, lesser alcohol enters your body.

Question 16

In terms of colour perception, humans are near the top in mammals. One mammal with better colour perception than us is the tetrachromatic reindeer (who are also some of the only mammals with ultraviolet colour perception and red-green perception; some dichromatic rodents do have UV perception from their blue rod). Most mammals do not have more than two colour rods in their eyes.Having better colour perception allows us to see colour patterns that are invisible or much more subtle to other animals. Almost every mammal is a dichromat with two colour rods, but humans and a handful of our closest Ape relatives are trichromats. To dogs, deer, lions, and a portion of humans, the distinction between green shades and red shades is much more subtle. This is a great survival trait. If a dog and you go on a walk, chances are that you will see another animal before you dog sees.

Question 17

Why haven’t car manufacturers made a car that is almost impossible to break? - In a crash, a car that doesn’t break would be disastrous for its occupants. Modern cars are designed to crumple and pieces are designed to come off in order to lose energy in an impact. Thus the car absorbs the impact of the accident, not the occupant.

Question 18

The immortal jellyfish is considered among the few animals on Earth that appears to live forever by reverting completely to a sexually immature polyp stage after having attained sexual maturity. In other words, this jellyfish has the remarkable ability to hit the reset button to start its life anew.

Question 19

Michael Crichton (author of Jurassic park, Congo , the lost world) the young undergrad assumed that the Harvard English department was too difficult for him, so he switched to premed, eventually earning his M.D. from Harvard Medical School.Although he never practiced medicine, he used his medical training to create the TV series ER in 1994.

Question 20

Apollo 11 - Neil Armstrong - Mission Commander, Edwin ‘Buzz’ Aldrin - lunar module pilot, Michael Collins - command module pilot.

Question 21

Liver is the only organ that can fully grow back. You can donate your liver and it will grow back

Question 22

Examples of Leapfrogging technologies - mobile phones and solar panel adoption.

Question 23

71% of earth is water

Question 24

“Uh-oh” were the last words of astronauts before the challenger shuttle malfunctioned.

Question 25

ISS is the most Expensive thing ever built by humanity costing over one $150 billion

Question 26

So, Einstein once said “sit with a pretty girl for an hour and it feels like a minute; sit on a hot stove for a minute and it feels like many hours. That’s relativity”
