Males and females have two ossicones, or hair-covered horns, on their heads. Male giraffes butt these horns together during play. A giraffe's neck is approximately 6 feet long and weighs as much as 600 pounds. Each of a giraffe's legs is also 6 feet long. The long legs and neck make it easier for giraffes to reach the leaves on tall trees.

Vitamin C and Effects on weight loss

Here are some information you should know about vitamin c. It can serve for the purpose of keep healthy or loose weight, play an important role in our daily life.

Kết quả hình ảnh cho vitamin c can help lose weight

Effects on Weight Loss

Although vitamin C doesn’t necessarily cause weight loss, it seems to be related to body weight. According to the review published in 2005 in the “Journal of the American College of Nutrition,” higher vitamin C intakes are associated with lower body-mass indexes. The authors of this review also point out that getting sufficient amounts of vitamin C increases body fat oxidation during moderate-intensity exercise. Therefore, vitamin C deficiency may hinder weight and body fat loss.

Sources of Vitamin C

The recommended dietary allowance for vitamin C is 90 milligrams daily for men and 75 milligrams per day for women, according to the Institute of Medicine. These amounts should be treated as minimum daily requirements. Vitamin C-rich foods include red peppers containing 95 milligrams in 1/2 cup, orange juice providing 93 milligrams on each 3/4-cup portion, a medium orange with 70 milligrams and one medium grapefruit supplying 64 milligrams of vitamin C, according to the Office of Dietary Supplements. Vitamin C is also a common nutrient found in multivitamins and other dietary supplements.

Too Much Vitamin C

More vitamin C isn’t always better, even when you’re trying to shed pounds. Ingesting too much vitamin C may affect the absorption of other nutrients -- and could cause diarrhea, abdominal cramps and nausea, according to the Office of Dietary Supplements. To help avoid side effects and potential health risks, adults should aim to ingest no more than 2,000 milligrams of vitamin C daily. That includes vitamin C from food and drink, as well as supplements.

Weight-Loss Considerations

You won’t lose weight, even if you consume high amounts of vitamin C, if your overall caloric intake is higher than the number of calories you burn throughout the day. Eating vitamin C-rich, high-fiber fresh fruits and vegetables helps fill you up without the extra calories. To effectively shed about 2 pounds per week -- the maximum recommended amount for long-term weight-loss success -- eat 1,000 fewer calories than you burn off daily, suggests the Centers for Disease Control and Prevention.

Tigers facts

1) Tigers are the largest wild cats in the world. Adults can weigh up to 363kg - that's about the same as ten ten year olds! - and measure up to 3.3m!

2) Tigers are carnivores, eating only meat. They mainly feed on large mammals such as deer, wild pigs, antelope and buffalo.

3) Tigers are solitary hunters, and generally search for food alone at night. They quietly stalk their prey until they are close enough to pounce - then they kill their victim with a bite to the neck or back of the head. Ouch!

4) Unlike most members of the cat family, tigers like water. They are good swimmers and often cool off in pools or streams.

5) When a tiger wants to be heard, you'll know about it, gang - because their roar can be heard as far as three kilometres away.

6) They may be big and heavy, but tigers are by no means slow movers. In fact, at full speed they can reach up to 65km/h!

7) These fierce felines have walked the earth for a long time. Fossil remains of tigers found in parts of China are believed to be 2 million years old. Yikes!

8) Every tiger in the world is unique - no two tigers have the same pattern of stripes.

9) Today, there are five subspecies of tiger: Bengal, South China, Indochinese, Sumatran and Siberian. Sadly, three subspecies of tiger have become extinct - Caspian, Bali and Javan.

10) Less than 100 years ago, tigers could be found throughout Asia. Sadly, hunting and habitat loss have put populations at risk, and today their range has been reduced to around 7% of its former size.

Don't cockroaches have ability of flight?

Don't cockroaches have ability of flight? Can you answer this amazing animal facts quesrion? Keep reading for answering

Many of the more than 3,500 cockroach species in the world can fly. The flying capabilities of cockroaches vary according to the particular species, and sometimes sexual category, to which they belong. In Canada, the German cockroach is the most important and prevalent cockroach species in the country. Depending on the region, other significant pest species present are the American, brown-banded, oriental, smoky-brown, and wood varieties of cockroach. Though both males and females of the German cockroach have wings, they do not fly except for short downward gliding. Meanwhile, both sexes of the smoky-brown species of cockroach are strong fliers. Amongst the brown-banded and wood cockroaches, only the males enjoy flying capabilities. Though not regarded as true flyers, both male and female American cockroaches maintain the ability to glide through the air. Both genders of the oriental cockroach lack the capacity to fly. The Canadian cockroach species capable of flying are generally only able to remain in the air for short amounts of time.

Despite possessing four wings, each flying cockroach uses just a single pair for air travel. Thick and protective, the front pair of wings displays the same coloration as the body of the cockroach and rests against the back of the insect when not in use. The back pair of wings remains hidden and protected beneath the front pair until the cockroach takes flight. When preparing to fly, cockroaches lift the front wings to expose the back wings. The insects keep the front wings lifted while flying and move through the air by using the back pair. In contrast to the front pair, the back wings of cockroaches that fly are membranous, thin and clear.

Even though many cockroaches can fly, the insects boast highly effective legs and prove more adept at running than flying. The body of a cockroach features three legs extending from each side of the thorax. Covered with setae and pointy spines, each leg varies in length and fulfills different yet interrelated functions that enable the physical act of running. With a total of six legs working together to propel the insects forward, cockroaches can cover a distance equal to roughly 50 body lengths in a single second. For a human to run the same distance as 50 of his or her own body lengths in one second, he or she would have to reach a speed of about 200 miles per hour.

What do penguins look like?

That is really amazing! Let’s discover awesome penguin facts by this article:

All penguins are black with white undersides, and are commonly described as wearing tuxedos. This color pattern acts as camouflage when the penguin is swimming, protecting it from predators. From underneath, the white belly blends with the bright water surface, and fromabove, the black back is indistinguishable from the dark water.

Penguin species can be grouped according to common characteristics. Banded penguins have black and white stripe patterns on their chests and heads. The crested penguins all have bright yellow or orange plumes on their heads. Brushtail penguins have long stiff tail feathers. The king and emperor penguins have bright yellow and orange chest and head patches, and the yellow-eyed penguin has a yellow crown. The fairy penguin's feathers are bluish. The emperor penguin is the largest, at nearly four feet tall and seventy-five pounds.

The small fairy penguin is sixteen inches tall and about three pounds. All have solid, heavy bones that help them dive deeply into the water. They have streamlined bodies that move smoothly through the water as they pump their strong, flipperlike wings and steer using their webbed feet and tails as rudders. Penguins can hold their breath for many minutes at a time, and they frequently leap out of the water, porpoiselike, to take inmore air. On land, penguins walk with an awkward sideways waddle. Because their short legs are set back on their bodies, they stand erect and must hold out their flippers for balance. Penguins often toboggan themselves by flopping on their bellies and pushing with their flippers and feet. Penguin feathers are tiny and stiff, overlapping to form a waterproof coat.

An underneath layer of down helps to trap warm air and protect the penguin from the cold water and wind. Penguins of the Antarctic region have an insulating layer of blubber. Those in temperate climates often have to cool themselves down by ruffling their feathers and holding out their flippers. They can control the flow of blood to their unfeathered areas, such as the feet and under their flippers, which helps regulate their body temperature. Penguins preen their feathers regularly, to spread waterproofing oil from a gland near the tail.

Penguins have very short legs, which are used under water for steering. On land it's not easy for a penguin to walk. Waddling seems to be the easiest way to walk with short legs (in fact this has been researched by scientists). In addition, some species displace themselves by hopping over the ground.

Although you don't see them, penguins do have knees and upper legs. They are completely enclosed within the penguin body. The upper leg is oriented horizontally. In contrast to other birds (whose feet are placed in the middle of their body) penguin feet are set all the way back, causing an upright stand.

Fascinating facts about elephants

Check out these interesting elephant facts and learn more about the biggest land mammal in the world.

Elephants perform "burial ceremony" when they lose a member of the herd. They gather around the body and stay in silence for a while. They will use branches to cover the body before they leave.

Elephants can recognize themselves in the mirror. Just few animals beside human toddlers are able to do that.

Elephants don't like to eat peanuts.

Due to their large size, elephants need to eat 150kg of vegetation per day.

Worn out teeth will be replaced 6-7 times in a lifetime (humans replace their milk teeth once in a lifetime).

Elephants flap their ears to cool themselves. If they are cooling themselves in the water, elephants will use their trunk as a snorkel.

Elephants live 60-70 years in the wild. In captivity they can live more than 80 years.

Elephants herds are matriarchal.
Female elephants live in groups of about 15 animals, all related and led by the oldest in the group. She’ll decide where and when they move and rest, day to day and season to season.
An elephant herd is considered one of the most closely knit societies of any animal, and a female will only leave it if she dies or is captured by humans.
Bull elephants court females by using rituals involving various affectionate gestures and nuzzles.
Female African elephants undergo the longest pregnancy — 22 months.
Elephants have been known to induce labour by self-medicating with certain plants.

Baby elephants are initially blind and some take to sucking their trunk for comfort in the same way that humans suck their thumbs.
Mothers will select several babysitters to care for the calf so that she has time to eat enough to produce sufficient milk for it.
Males will leave the herd as they become adolescent, around the age of 12, and live in temporary “bachelor herds” until they are mature enough to live alone.
Male elephants are normally solitary and move from herd to herd.
Homosexual behavior in elephants is common and well-documented.

Where do tigers live?

If you have ever caught yourself pondering what do Tigers live? You can’t say that you haven’t because that means that you wouldn’t have ended up here! Let us teach you all about habitats of one of the most amazing big cats in the world.

The tiger is native to Asia from the Caucasus and the Caspian Sea to Siberia in the north and Indonesia and even in Borneo and the Philippines in the south. Tigers use to had a huge habitat because they are able to adapt to different types of environments which range from the Siberian taiga to open grasslands and tropical mangrove swamps. However as it can be seen on the map, their habitat has been reduced dramatically.

Tigers are extremely territorial though so they will fight other animals and other tigers that invade their space. This problem has become more of an issue due to the natural environment for tigers being destroyed at an alarming rate, as a male tiger may have a territory of up to 60 to 100 square kilometers, while females up to 20 square kilometers, as this numbers change according with the habitat and subspecies. As a result they have to venture into new territories to be able to find adequate amounts of food.

Tigers tend to live on their own, depending on themselves for survival. They will only be seen with other tigers when they are looking for a mate or in the case of females when they are taking care of their offspring. The males have more personal territory than females when it comes to their natural habitat. It is natural for the females to have territories that overlap that of males. This is more acceptable than if another male tries to invade that same type of space.

What is importance of science?

We all know for sure that it is importance to find out and learn about science facts but what is importance of science? Why should we learn about it?

Can you imagine a world without science? You wouldn’t have to worry about being late to work or finding your car keys because, well, jobs and cars wouldn’t exist. You would be living in a cave or a rudimentary built shelter, at best, wondering whether you’ll be able to hunt something for your next meal, or get killed and become some wild animal’s next feast in the process. The moment that early humans decided to take action into securing their survival marked the birth of science, as that’s the moment when they started asking themselves two vital questions about the world surrounding them: “How?” and “Why?”.

Basically, that’s exactly what science is about: understanding how things work and why, and the answers science gave us so far allowed us to survive, ensure our survival and improve our lifestyle in the process, so I don’t think it’s exaggerated to say that science is the most important element of our existence. If you want a proof of just how awesome science is, check out this online course on geology and you will learn about the origins of our planet, how it was formed and why it is in the form we know it today – starting from billions of years ago, all the way up to the present day.

You might be surprised with the owl facts

Here are some amazing facts about owl for those who love to know more about animal facts:

Many owl species have asymmetrical ears that are different sizes and different heights on their heads. This gives the birds superior hearing and the ability to pinpoint where prey is located, even if they can't see it.
Several owls species have ear tufts on their heads but they aren't ears at all. These tufts of feathers may indicate the bird's mood, help keep it camouflagedby mimicking branches or leaves or be used to show aggression.
The flattened facial disk of an owl funnels sound to the bird's ears and magnifies it as much as ten times to help the owl hear noises humans can't detect.
Feather coloration is species specific. It can be brown, rust, gray, white and black. Mix of the colors provides nice camouflage for both predators and prey.
Some species of owls have ear-like structures on their head. They cannot detect sound, but serve as structures which provide camouflage. They can be also used to show aggression.
Owls have excellent sense of hearing. Ears are located on the both sides of the head, behind the eyes. They are often located on different heights, providing better reception of the sound, which is important for detection of the prey.
Although it looks like the owl can turn its head completely (360 degrees), it can move it only to a certain extent (just 270 degrees). Owl can look across its shoulder, but it cannot rotate the head a full circle.
Owls are farsighted, which means that they cannot clearly see the objects which are in front of their eyes.
An owl's eyes are supported by bony eye sockets and they cannot turn their eyes. Instead, owls rotate their heads up to 270 degrees (135 degrees to either side), but they cannot turn their heads all the way around.
An owl has three eyelids: one for blinking, one for sleeping and one for keeping the eye clean and healthy. The third eyelid is also called the nictitating membrane, and many other birds also have it.
A barn owl can eat up to 1,000 mice each year, usually swallowing them whole. Many farmers try to attract barn owls to help control rodent populations in agricultural fields.
Owls are carnivorous and will eat rodents, small or medium sized mammals, nocturnal insects, fish and other birds, including smaller owls. After digestingtheir food, owls regurgitate hard pellets of compressed bones, fur, teeth, feathers and other materials they couldn't digest. Ornithologists study those pellets to learn more about an owl's diet.
Owls have zygodactyl feet with two toes pointing forward and two toes pointing backward, and all their toes have sharp talons. This gives the birds a stronger, more powerful grip so they can be more effective predators.

Facts you didn't know about pigs before

Keep reading for more interesting information about animal facts. this is pig facts:

Humans farm pigs for meat such as pork, bacon and ham.
Some people like to keep pigs as pets.
Wild pigs (boar) are often hunted in the wild.
In some areas of the world, wild boars are the main source of food for tigers.
Feral pigs that have been introduced into new areas can be a threat to the local ecosystem.
Pigs can pass on a variety of diseases to humans.
If you’ve ever suggested that someone was ‘sweating like a pig’, then you’d be wrong. Pigs have hardly any sweat glands, and one of the best ways for them to cool down is to wallow in all of that glorious mud.

Pigs do not “eat like pigs” or “pig out.” They prefer to eat slowly and savor their food.
Suzanne Held, who studies the cognitive abilities of farmed animals at the University of Bristol’s Centre of Behavioural Biology, says that pigs are “really good at remembering where food is located, because in their natural environment food is patchily distributed and it pays to revisit profitable food patches.”
Pigs are clean animals. If given sufficient space, they will be careful not to soil the area where they sleep or eat. Pigs don’t “sweat like pigs”; they are actually unable to sweat. They like to bathe in water or mud to keep cool, and they actually prefer water to mud. One woman developed a shower for her pigs, and they learned to turn it on and off by themselves.

In his book The Whole Hog, biologist and Johannesburg Zoo director Lyall Watson writes, “I know of no other animals [who] are more consistently curious, more willing to explore new experiences, more ready to meet the world with open mouthed enthusiasm. Pigs, I have discovered, are incurable optimists and get a big kick out of just being.”

Interesting plant facts

1. The earth has more than 80,000 species of edible plants.

If you’re ever in the mood to try something new, the good news is that there is certainly food you haven’t tasted yet still growing somewhere in the world.

2. 90 percent of the foods humans eat come from just 30 plants.

Out of tens of thousands of plants we could eat, mankind chooses to consume only about 30 of them. It’s crazy to contemplate how limited our diets are compared to all of the different foods we could be eating. If you think the selection of which plants we eat has anything to do with their nutritional benefits, however, you’d be wrong …

3. Nutrition doesn’t factor into the crops we do mass produce.

The world’s largest farmers have pursued certain crops because they can grow a lot of them more quickly, easily and inexpensively to turn a better profit. As a result, most of the most healthful plants stay off of our dinner plates because they aren’t available at grocery stores. Still, sustenance isn’t the only thing humans rely on plants for …

4. 70,000 plant species are utilized for medicine.

As it turns out, humans are more diversified in the plants we use for medicine. Although a large portion of that figure applies to traditional medicine, modern medicine is not excepted from plant help. Half of the drugs prescribed in the U.S. have plant origins, many coming out of the rainforest, yet …

5. Only one percent of rainforest plants have been studied for medicinal potential.

Given how valuable plants can be medicinally, the rainforest houses a host of possible cures for ailments new and old. This untapped resource could still hold the key to medical breakthroughs. Of course, a lot of this potential could be lost considering …

6. 80 percent of the Earth’s original forests have been cleared or destroyed.

The same forests that dominated the land 8,000 years ago are all but gone. Approximately four-fifths of the forests are gone thanks to human intervention—just think of how many plant species may have been lost in that process. If you thought protections were in place, actually …

7. Just 10 percent of the world’s plant-rich areas are protected.

Of the most biodiverse areas on the planet, only 10 percent are officially “protected” to ensure the survival of a multitude of species—plant and animal alike. Worse still, many of the supposedly protected areas are done so nominally only, leaving plants threatened by external factors they should be safeguarded from. This is especially problematic because …

8. More than half of plant species are native to just one country.

Chances are, a plant you find in one part of the world is not currently growing anywhere else. As plant habitat is ruined, there’s little point in hoping that the killed plants could be found and harvested somewhere else in the future.

All amazing and interesting facts
