Do we know how many tigers are left in the forest?

The International Union for Conservation of Nature (IUCN) records the population size of thousands of threatened species. Their i gures are estimates based on many surveys.

Regional Conservation Body. It is a mixture of direct observation, cameras are found on water holes and draping or claw marks. The most recent i gures, which are from 2011, suggest that there are about 3000 tigers left in the forest.

The tiger has been listed as endangered in the IUCN Red List since 1986. As of 2015, the global wild tiger population was estimated to number between 3,062 and 3,948 mature individuals, down from around 100,000 in the early 20th century, with most remaining populations. Being in a small pocket separates them from each other. Major causes of population decline include habitat destruction, habitat fragmentation, and poaching. This, coupled with the fact that it lives in some of the more densely populated places on Earth, has caused significant conflict with humans.

How do electric eels hunt?

How do electric eels hunt?

The electric eel is a formidable freshwater predator, capable of emitting a powerful voltage of electric water to submerge the passing water. The release of electric pulses has a direct ef ect on the muscles of the i sh, causing them to twitch or convoy, turning the predator away from their position. Electric eels are capable of this feat because they have electric parts that can store electricity like batteries. When an eel plans to attack,

A burst of electricity up to 600 volts will discharge thousands of specialized electrocyte cells within its organs. Because of their poor eyesight, electric eels will use the same technology to navigate hunters' wards and their gloomy freshwater surroundings.

Electric eels have three pairs of stomachs that produce electricity: the main organ, the Hunter's limb and the true limb. These organs make up four fifths of its body, and give electric eels the ability to produce two types of electric organ discharge: low voltage and high voltage. These organs are made up of electrocytes, lined up, so a flow of ions can flow through them and stack so that each potential is added to the gap.

Why do dogs lick people?

Why do dogs lick people?

Ever wondered what your canine companion is after?

Although it is believed that dogs lick humans to show affection, there are several other theories to explain the behavior. One is that we taste great. Salty sweat and food residues not only look great, but also give information about where we are and what we have eaten. Lick is also considered a learned behavior. Puppies learn to lick to keep themselves clean, but also communicate to greet each other and strengthen relationships within the group. In adult dogs, licking is also a way for a dominant pack member to show humility, so it is likely that dogs lick us for the same reasons.

Why are jungle birds more colourful than others?

Why are jungle birds more

colourful than others?

How jungle birds’ bright plumage attracts female attention.

In most species only the male is brightly colored, which is central to understanding how it evolved. Being colored makes you more visible to hunters, and women choose colored men as they demonstrate how long they must live. All of her axioms, male and female, benetite from her superior genes, harm the male alone with the added risk. In a dense forest environment filled with hiding places, this mating advantage is totally worth it. In more exposed environments, predation is a major immediate concern, making it more beneficial for both genders, who are younger.

What makes seawater so salty?

What makes seawater so salty?

The natural seasoning that causes the lavour of the sea.

Most salt in the sea comes from a process that occurs on land. Rain contains carbon dioxide from the atmosphere, which makes it acidic. As rain erodes rocks on the ground, this ion releases atomic particles that carry electric charge. Rivers and streams eventually carry these dissolved ions into the ocean. Some are removed from the water by various plants and animals, while other ions - mainly sodium and chloride - are more concentrated. These are the two ions that make seawater salty. It was estimated that if all the oceans evaporated and their salts spread evenly over the entire surface of the Earth, it would form a 152 m (500 ft) thick layer.

What is solar wind?

What is solar wind?

How do charged particles ejected from the Sun affect Earth’s magnetic field?

Solar winds move at a speed of 400 kilometers (250 mi) per second from the Sun. Corona's intense heat - The outermost part of the Sun's atmosphere raises the particles to such a level that the Sun's gravitational field can no longer hold onto them and they escape into space. The strength of solar wind varies, which is capable of disrupting space weather technology, such as the Global Positioning System (GPS) satellite.

What is a photon?

What is a photon?

Just how do these tiny packets of light work?

A photon is one of the primary particles of the universe and is responsible for its basic structure. Photons are responsible for electromagnetic forces, one of the fundamental forces of nature and are often considered by many as the basic unit of light. They are also responsible for forces in the electromagnetic field and are the main component of light that enables it to travel throughout the universe.

Photons are basically small packets of energy, or electromagnetic waves, but have no mass or electric charge. When energy changes, they are released from atoms, travel at the speed of light and can exist as both a wave and a particle. When we look at light, what we are actually seeing is the emission of photons from excited atoms.

How do painkillers

cure headaches?

The science behind the pills that manage pain.

We all feel pain differently depending on the pain or severity of the pain, as well as our health and our pain threshold. When you are in pain, the nerve endings carry pain signals through the spinal cord to the brain. The brain then explains the level of pain.

There are two major types of commonly used pain relievers. The first includes ibuprofen and paracetamol, which block the body's prostaglandins (inflammation and pain-causing chemicals) at the source of pain, reducing inflammation in the area and reducing the intensity of pain. These 'aspirin medicines' are often used for mild to moderate pain, but they can only work up to a certain intensity of pain. There are a variety of pain relievers within this group, such as anti-inflammatory drugs, such as ibuprofen, which are commonly used to treat arthritis, sprains, and strains. Aspirin is used to help reduce the risk of blood clots when used in low doses, as they thin the blood. Paracetamol is known as an analgesic, which is used to reduce pain and lower the temperature.

Other types of pain relievers include morphine and codeine (narcotic drugs), which block pain inhibitors in the spinal cord and brain. This is for the more serious. As both types of pain relievers use slightly different methods to treat pain, they can be combined, such as co-codamol, which mixes codeine and paracetamol

How are light trails captured?

How are light trails

captured?

How are these bright, abstract streaks of light caught on camera?

Light trails are a colorful and creative effect that photographers can capture by employing long-exposure shooting on their camera. The basic principle of building light traces is that by manually dropping the camera's shutter speed to a very low level, light is artificially captured by the sensor for a long time, with each vehicle passing by Its light is tracked and recorded.

Visible distance of road.

To take a shot this way, find a roadside vantage point in which no other moving objects other than the passing vehicles are visible. Second, mount the camera on the tripod, as stability is important during shooting for long exposure imagery. This is because if a camera shake occurs when the unit's shutter is open, the captured light will lose its direction and smudge the entire image. Next select the shutter priority setting on the DSLR camera and leave the shutter speed at the desired level - such as for shots,

This means at least 30 seconds of performance. Finally, automatically focus on the background of the scene and use an external remote to take pictures. Interestingly, a very similar process is also used in lighting, illustrating a technique where streaked light is manually controlled by the photographer, using a light-emitting diode (for drawing custom streaks on a dark background). LEED) and painting is essentially done in light. .

How do Venus flytraps work?

How do Venus flytraps work?

Discover how these plants lure their prey.

Venus flytraps, like the rat-eating carnivorous plant, develop in marshy soils that are low in nutrients, so they need to find another source of food to maintain them, namely the pests that land on their leaves. These leaves are about eight to 15 cm long and are edged 'hinged' along the midline with shiny teeth around the edges. Folding and trapping is triggered by pressure on six sensitive hairs, which when stimulated will close the leaf.

In about half a second, though the actual nature of the action is still being debated. Along with these sensitive hairs, there are also glands on the leaf surface that secrete a sap that digests the body of the insect. This process takes about ten days, after which the leaf reopens.

Which animal has the best sight?

What can see further than anything else?

Birds of prey claim the greatest visual acuity of all animals and zoologists believe that some hawks and eagles are eight times faster than us. The retina of a eagle plays in about 1 million sensory cells per square millimeter - about five times what you find in a human retina. It Pays: Some birds of prey can see and track a rabbit 1.5 km (0.9 mi) away! If you measure vision in terms of light spectrum perception rather than sharpness, then Mantis is a shrimp shampoo. Mantis shrimp experience 11 or 12 primary colors, embarrassing all three of us, and they also see ultraviolet and infrared light.

What is purpose of this world ?

Many animals are available in this world but the human is very intelligent animal this animal use intelligent to become a satisfying and falaxibal life.
But this animal go to wrong side this animal by help of intelligent destroy world atmosphere and injured many other animal.

What is purpose of life? Thought about your life why God who make this world why make you? Every action by reason.
Every human common life style is like make money and sell it for liability and produce children after the end.

But if you think you are special and you can change the world by your actions and your thoughts you live for other people who need you.

Which people who become a successful in his life those people helps other those people live for another people.

What is success?

Everyone become a successful but no one know how to become a successful common people think get education properly and get degrees and get high salary job you become a successful.
Is this success?

Success is live for another people and give him whatever he needs

Why are decoy flares?

2020-04-15T20:54:00.002-07:00

What are decoy flares?

Confusing missiles to avoid destruction

The decoy works by generating heat signature in excess of the launch vehicle's jet engine. It has a great eco to induce any incoming heat-seeking missile's homing system to lock onto flares signatures instead of aircraft, allowing it to explode at a safe distance and save the pilot's life. There are two main types of counterclaim fl - pyrophoric and pyrotechnic. The former is automatically activated by exposure to air and the latter precedes the ﬁ ring by mechanical removal of a friction cap. Any type of flare structure is often designed to mimic the heat signature of a Counter C missile system or launch jet.

What causes red tides ?

What

causes red tides?

Why crimson seas are not as unbelievable a sight as you might first think....

A red tide is the rapid accumulation of a mass of aquatic algae, made up of mobile single-celled microbes, known as dinoflagellates - meaning the nature of tail-like projections spreading them through water. Due to 'whipping whip'. Algae grow, or blossom, more rapidly than usual to consume more nutrients that have suddenly increased from the cool depths of the ocean below. The red color is down to the presence of a certain species of dinoflagellate, or phytoplankton. With more abundant diatom algae, dinoflagellates make up the majority of the plankton of the ocean. Despite the rather staggering appearance of a sea that has turned red, many algal flowers are actually completely harmless. However, you should not consume seafood after red tide as some phytoplankton may release harmful substances into the water. Some dinoflagellates can produce toxins when eaten by other creatures, and harmful substances are then concentrated inside the organisms that feed on them, and later any humans who feed on contaminated seafood. Billions of microscopic dinoflagellates in a red tide can also cause spectacular bioluminescence at night. One species in particular - Lingulodinium polydrum - can make its light from within. When the creature is jerked or collides with it

Some in the ocean, a chemical reaction occurs when an enzyme called luciferase and a substrate called luciferin, both contained within the organism, combine. It is a catalyst for a chemical reaction that releases a flash of blue light. When it happens millions of times simultaneously, the effect is quite remarkable for the audience.

What is coral ?

What is coral?

Is it animal, vegetable or mineral?

While corals may look like reefs and share many characteristics of plants, they are actually animals. To be precise they are aquatic marine invertebrates (known as polyps) that live in warm shallows of clear coastal waters located around the world. A large number of marine organisms make their home among the corals, making them the most abundant and diverse habitat on Earth. Because the nutrients that the plankton needs to feed on are better dissolved in deep, cold water, warmer layers become less attractive places to capture large numbers of floating plankton. Therefore, the upper shallows remain warm and clear - ideal living conditions for micro-algae, who use sunlight to combine carbon dioxide and water to create their own food source, which they use with their coral Share.

Corals remain in partnership with single-celled Zooxanthella algae, which are also responsible for the bright colors. If the algae die, the coral will turn white, a harmful effect called coral bleaching. As such, jellyfish corals are cididarians, except that they are contained on the spot by a tube attached to a surface (usually rock), rather than swimming freely like jellyfish. Cnidarians have a simple body, with a central mouth opening, surrounded by a stinging tentacle. The coral polyp is a soft-bodied organism that is made up of single-celled algae and lives within a large community of similar polyps called colony. They use calcium and a variety of other minerals in seawater - along with the food waste they produce - to build their own protective calcium carbonate skeletal shelters. When the coral dies, the remains of a rigid, chocolate skeleton are left behind and new polyp will develop on top of these. The coral skeleton is formed of sedimentary limestone when compressed over several thousands of years. Over hundreds of thousands of years, a colony of polyps can grow extensively with other colonies to join a larger colony.

Why does water turn white?

Discover which part of the course of the river provides the setting for some of the world's most dangerous turbulent waters.

White water is in the upper part
The course of a river when the gradient and obstructions distract the flow of water, causing it to churn and create bubbles. These bubbles leave the ect behind, which collides with light, making the water appear white. Whether a river flows smoothly depends often on its speed, and along the banks of the Steppard River, faster water will flow.

The flow becomes turbulent due to a combination of obstacles such as fast flowing water and rocks, with unexpected variations in search speed and direction that provide the setting for some of the world's most dangerous turbulent waters, part of the course of a river. . Water turned white? Water. This produces many different characteristics in the river. Where the water doubles back on itself, there are open pockets with bubbles; These provide very low bounce and. Hole '. Objects lodged in the river can act as springs, allowing water to pass through, but blocking large debris. The areas in which water rises rapidly, on the surface below the rocks, are weathered, forming undercuts.

The challenges of navigating the characteristics of white-water rapids, whether jutting rocks or whirlpools, attracts cankers and rafters every year.

What is the coast eroding?

Why is the coast eroding?

Learn about the amazing processes that are building and breaking our shores right now….

Water is not given enough credit for its role in shaping the Earth. Tectonic plates and volcanic eruptions are often cited as the culprits for most land characteristics, but it is the water and wave action that shape the beaches of our world. When a wave crashes on shore it carries sediment that gets suspended in water, and it also pushes large sediment along the ground. When a wave is heard it also carries the sediment with it, but rarely at a uniform rate. If a wave accumulates more sediment then it goes away, then it becomes sediment, which expands the coastline. Conversely, when more sediment is being removed than added, the coastline is reoriented or destroyed. Coastal erosion today accounts for the most amazing landforms in Australia from the Twelve Apostles to the White Cliffs of Dover, England. The type of coastline formed by erosion depends on any number, including wave action and wind strength, sediment formation of the beach, and types of nearby rock. Coastal erosion is a very slow process that takes hundreds of years, but scientists believe that climate change is accelerating things. Climate change has caused an increase in sea level and the frequency and severity of hurricanes - both of which play an important role in erosion. Indeed, the UK's Environment Agency estimates that the British Coastline may diverge from 67–175 m (220–575 ft) over the next 100 years.
