Why are jungle birds more colourful than others?

चित्र
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?

चित्र
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?

चित्र
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?

चित्र
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?

चित्र
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 blo...

How are light trails captured?

चित्र
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 shutte...

How do Venus flytraps work?

चित्र
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?

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.

Why are decoy flares?

चित्र
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 ?

चित्र
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 ...

What is coral ?

चित्र
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 al...

Why does water turn white?

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 ...

What is the coast eroding?

चित्र
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 form...
