Cool fun facts of life

"The ocean looks blue because red, orange and yellow (long wavelength light) are absorbed more strongly by water than is blue (short wavelength light). So when white light from the sun enters the ocean, it is mostly the blue that gets returned. Same reason the sky is blue."

In other words, the color of the ocean and the color of the sky are related but occur independently of each other: in both cases, the preferential absorption of long-wavelength (reddish) light gives rise to the blue. Note that this effect only works if the water is very pure; if the water is full of mud, algae or other impurities, the light scattered off these impurities will overwhelm the water's natural blueness.

Gross then asks, "So why are sunsets orange?" Several people to wrote in to correct or clarify that comment.

Perhaps the most helpful response came from Michael Kruger of the department of physics at the University of Missouri. He sent the following reaction:

"The answer to why the sky is blue isn't quite correct although there are many funny pics to prove it. The sky is blue not because the atmosphere absorbs the other colors, but because the atmosphere tends to scatter shorter wavelength (blue) light to a greater extent than longer wavelength (red) light. Blue light from the sun is scattered every which way, much more so than the other colors, so when you look up at the daytime sky you see blue no matter where you look. This scattering is called 'Rayleigh scattering'; the amount of scattering goes as the frequency of the light to the 4th power. By the way, this effect is most prevalent when the particles that do the scattering are smaller than the wavelength of light, as is the case for the nitrogen and oxygen molecules in the atmosphere.

"Now we are in a position to figure out why sunsets are reddish! When the sun is setting, the light that reaches you has had to go through lots more atmosphere than when the sun is overhead, hence the only color light that is not scattered away is the long wavelength light, the red.

"We can also answer why clouds, milk, powdered sugar and salt are white. The particles in these materials that are responsible for scattering the light are larger than the wavelength of light. Consequently, all colors of light are scattered by more or less the same amount. Much of the scattering in milk is due to the lipids (fat). If you take out the fat, the milk will not scatter as much light; that is probably why skim milk looks the way it does.

If there is a  real fight of Lion and tiger, which would win? Let's see:

Well, let’s talk size first. Tigers are heavier, weighing up to 800 pounds to the lion’s 550. But the two cats aren’t so different in size. Here, their profiles are superimposed:

You might remember from high school health class that muscle weighs more than fat, which helps explain the tiger’s extra pounds. So it seems that the tiger would have a physical advantage over the lion.

But it turns out that we have some historical data to add to this conjecture, too. In ancient Rome, the tiger-lion face-off wasn’t uncommon. In 1959, a reader asked the Spokesman-Review this question, and the paper, in turn, asked William Bridges, the curator of publications at the Bronx Zoo. He told them that “back in the day of the Roman Coliseum, the smart money usually backed the tiger.” While we don’t have any great descriptions of the outcomes, ancient paintings of the event usually showed the tiger winning. And in the late 1800′s, the Gaekwad of Baroda, an Indian ruler, arranged a fight between the two beasts. Before the fight began, those running the bettor set the odds at 1 to 37,000 that the tiger would win. It did, and the Gaekwad lost 37,000 rupees.

And in 2011, a tiger killed a lion with a single paw swipe in a run in at Ankara Zoo in Turkey. The tiger apparently found a gap in the fence, and made its way into the lion’s enclosure. When they met, the tiger severed the lion’s jugular vein in just one stroke. Craig Saffoe, a biologist at the Smithsonian Zoo, also generally favored the tiger, telling LiveScience, “What I’ve seen from tigers, they seem to be more aggressive; they go for the throat, go for the kill. Whereas the lions are more, ‘I will just pound you and play with you.’”

But fighting in an arena, and even in a zoo, is quite different than fighting in the wild. If a tiger were to meet a lion without cages or screaming fans, what would happen? That’s actually a question that some conservationists are having to answer right now. There’s a plan to move some Asiatic lions to from the Gir forest to Kuno Palpur, where there are tigers. The University of Minessota’s Lion Research Center says that the plan has been delayed for fear that the native tigers would kill the lions. But in the wild, they say, tigers and lions fight quite differently:

Coalitions of male lions usually fight as a group against territorial rivals, so a tiger may have an advantage in a one-on-one encounter, since this is the typical mode of combat for a tiger. However, a lion coalition of 2–3 males would have a clear advantage over a lone tiger. A group of 2–4 female lions would have a similar advantage over a lone tigress.

They conclude that while one on one, a tiger would certainly best a lion, in the wild the lion pride could hold their own against the solitary tiger.

All background information about vitamin C will appear in this writing, just keep reading to know

Vitamin C

It is found in sufficient amount in the fresh fruits, animal liver, milk, green vegetables, blackcurrant, guava, all the citrus fruits (like orange, amla, lemon, grapefruit), broccoli, strawberries, papaya, cauliflower, pineapple, cantaloupe, watermelon, garlic, cabbage, mango, grape, banana, onion, carrot, apple, beetroot, pear, cucumber and etc. However, it gets destroyed over high temperatures while boiling the food.

Vitamins C is required by the body for the production of collagen which makes the skin healthy and glowing, hair strong and long, teeth and gums healthy, blood vessels and joints cartilage powerful and etc. It also acts as an antioxidant, prevents the body from tissue damage (free radicals), enhances the iron absorption in the intestines and lowers the risk of cancer.

It enhances the wound healing process and plays a significant role in red blood cells formation. It also enhances the level of brain chemical called as noradrenaline (an important neurotransmitter) and improves the alertness and concentration power.

Deficiency of Vitamin C

Its deficiency causes scurvy and lower level may lead to the variety of heart diseases, lung problems, poor wound healing, strokes, cancer, bleeding gums, skin discoloration, weak immune functioning, frequent cold and other infections.

Daily Requirement of Vitamin C for Different Age Group

Daily requirement of this vitamin depends on the age and sex of the person. I have mentioned below the daily requirement of the vitamin C for different age group people:

Infants between 0-6 months of age require 40 mg/day.

Infants between 6-12 months of age require 50 mg/day.

Children between 1-4 years of age require 15 mg /day.

Children between 4-9 years of age require 25 mg /day.

Males and females between 9-14 years of age require 45 mg /day.

Males between 14-19 years of age require 75 mg /day.

Males above 19 years of age require 90 mg /day.

Females between 14-19 years of age require 65 mg /day.

Females above 19 years of age require 75 mg /day.

Pregnant women from 18 and above years of age require 80-85 mg /day.

Lactating women from 18 and above years of age require 115-120 mg /day.

Other amzing information: sophie giraffe

Giraffes are the world's tallest mammals, thanks to their towering legs and long necks. As we know, a giraffe baby legs alone are taller than many humans.

Diet

Giraffes are herbivores, which means they eat only plants. Their long necks allow them to reach leaves, buds and branches high up in mimosa and acacia trees. They can eat hundreds of pounds of leaves per week, according to National Geographic.

Though these animals eat a lot, giraffes can go without drinking for weeks at a time. They get most of their moisture from the vegetation they eat.

Offspring

As in cattle, female giraffes are called cows, while the males are called bulls. After mating, the cow will have a gestation period of around 14 months. During birth, the calf will drop to the ground, since mother giraffes give birth standing up. The fall can be as far as 5 feet (1.5 m), according to National Geographic.

New calves are quite large, at 6 feet tall (1.8 m), 100 to 150 lbs. (45 to 68 kg), according to the San Diego Zoo. They are also agile. At just an hour after birth, they can stand up and walk around. 

Giraffe mothers often take turns watching over the calves. Sometimes, though, the mother giraffe will leave the calf by itself. When this happens, the infant will lie down and wait for its mother to return.

At 3 to 6 years old, calves are fully mature. The animals can live up to 20 years.

Learn all basic tigers facts and information by this writing:

Diet

Tigers mainly eat ambar deer, wild pigs, water buffalo and antelope. Tigers are also known to hunt sloth bears, dogs, leopards, crocodiles and pythons as well as monkeys and hares. Old and injured tigers have been known to attack humans and domestic cattle.

Population

In the early 1900s, there were around 100,000 tigers throughout their range. Today, an estimated total of around 3,000-4,500 exist in the wild. Below is a breakdown of tiger numbers by subspecies.

1. Bengal tiger: Less than 2,000
2. Indochinese tiger: 750-1,300
3. Siberian tiger: Around 450
4. Sumatran tiger: 400-500
5. Malayan tiger: 600-800
6. South Chinese tiger: Extinct in the wild
7. Caspian tiger: Extinct
8. Javan tiger: Extinct
9. Bali tiger: Extinct

The Tale of the Tiger

Recognizing a tiger at the zoo is easy. But in their natural habitat, tigers are really hard to find. That’s because their unique orange, black and white stripe pattern helps them blend into the forests and grassy areas where they live and hunt.

Tigers are carnivores. They are quiet, patient hunters with large powerful paws and teeth to help them catch and eat their prey. Some of their favorite meals include pigs, deer, rhinoceroses, and even small elephants.

Tigers hunt for their food, but they are also hunted by humans for their valuable fur and body parts. Because of this, tiger researches think there may only be 3,500 tigers left in the world. This makes them an endangered species.

Range

Historic tiger range ran from Turkey through South and Southeast Asia to the far eastern shores of the continent. Today, they are only found in South and Southeast Asia, China and the Russian Far East.

Behavior

Tigers occupy a variety of habitats from tropical forests, evergreen forests, woodlands and mangrove swamps to grasslands,savannah and rocky country. They are mostly nocturnal (more active at night) and are ambush predators that rely on the camouflage their stripes provide. Tigers use their body weight to knock prey to the ground and kills with a bite to the neck. They are also very good swimmers and have been known to kill prey while swimming.

Tigers essentially live solitary lives, except during mating season and when females bear young. They are usually fiercely territorial and have and mark their large home ranges.

Reproduction

Mating Season: In tropical climates, mostly from around November to April; during the winter months in temperate regions.

Gestation: 103 days.

Litter size: 3-4 cubs.

Cubs follow their mother out of the den at around 8 weeks and become independent at around 18 months of age. They leave their mothers at about 2 ½ years. Mothers guard their young from wandering males that may kill the cubs to make the female receptive to mating.

Have you known about some following interesting cockroach facts before:

1. Cockroach Eating Contests

If a cockroach is beheaded it will never die because of the loss of its head. The only thing killing it will be the thirst as it can’t drink water without a head. Their respiratory system has nothing to do with the mouth as they can breathe through little pores in their body.

Cockroach Eating Contests

The Six Flags Great America theme park in Chicago came up with a very gag-worthy promotion for Halloween back in 2008. They offered park passes to the winner of a contest to eat the most live cockroaches in the space of five minutes. A doctor advised people against taking part because of the microorganisms that live inside the insects. Nevertheless, the parkresurrected the contest in 2011, citing “popular demand.”

The true risk of this sort of contest was shown in Florida. A competitor named Edward Archbold died shortly after a pet shop held a roach-eating competition with a python as a prize. He suffocated after choking on bits of cockroach that got lodged in his throat. Six Flags decided to call off their contest following the death.

2. A Cockroach Can Cause Many Diseases

Cockroaches love to live in filth and dirty places and in these interesting cockroach facts; this fact is about their contaminating abilities. A cockroach is usually completely enveloped in filth. They can move as fast as 3 miles per hour. It will take only a few minutes for a single cockroach to fully contaminate a house. That’s why they can cause many dangerous diseases among humans.

3. Cockroach Facts: German Cockroaches

German cockroaches are considered the most dangerous than others cockroaches. They are the most common type found in almost every nation. They can cause illness, allergy and in some severe cases breathing problems in humans. They can become fully adult within a time span of 36 days.

4. Cockroaches Like to Live in Small, Closed Places

There are many interesting cockroach facts and this fact will tell you about their habit of living in small and closed places. All the cockroaches are thigmotropic i.e. they are sensitive to touch from all sides. They like to crawl in small and tight places to fit in. They really seem to enjoy a place closed from all sides. A pregnant mother cockroach can even manage to fit in a place not wider than two vertically combined coins.

5. Cockroach Facts: Cockroaches Can’t Live Without Water

They are cold blooded and can survive for a month without any food. They usually don’t remain without food for that much long as they can eat anything in their way. Their real problem is the shortage of water. No water for a week can kill them. So primarily they need water to survive not the food.

6. Cockroaches are used as Food in Some Countries

In these cockroach facts, this fact is probably the weirdest of all. Even though they are hated by most people especially women but still there are places in the world where they are served as food. Countries like Ghana, Thailand, Mexico, China and even in some places of America they are served as food. In the November of 2012 a cockroach eating contest was held. But unfortunately the winner of the contest died soon after the competition. He choked to death on the small pieces of roaches in his throat.
