The Ribbon Eel

Image
The ribbon eel , Rhinomuraena quaesita , or Bernis eel, is a species of saltwater eel, the only member of the genus Rhinomuraena of the Muraenidae (Moray eel) family of order Anguilliformes. What is now known as Rhinomuraena quaesita also includes the former Rhinomuraena amboinensis . R. quaesita was used for blue ribbon eels and R. amboinensis for black ribbon eels, but these are now recognized as the same species. The ribbon eel is native to the Indian and Pacific oceans. The ribbon eel is an elegant creature with a long, thin body and high dorsal fins. The ribbon eel can easily be recognised by its expanded anterior nostrils. Juveniles and sub-adults are jet black with a yellow dorsal fin, while females are yellow with a black anal fin with white margins on the fins. The adult males are blue with a yellow dorsal fin. The ribbon eel grows to an overall length of approximately 100 cm (36 in), and has a life span of up to twenty years. The ribbon eel is the only moray eel that

Is there something smaller than the subatomic particles we know ?

Image
We all know that matter is made up of atoms which is made up of even more tiny particles called electron ,protons and neutrons. Are there anymore tiny particles than that ?? well lets see There are particles inside the electron and the protons there are two types Lepton  and Quarks . Each have six different types of particles. Leptons  are present in electrons and have 3 generation of particles they are electronic leptons, muonic leptons and taunic leptons each have 2 types Electronic leptons contain electron and electron nuetrino (They are called as nuetrino because they are lightly nuetral) Muonic leptons contain muo and muo nuetrino Tuanic leptons contain tua and tua nuetrino Quarks are present in protons and nuetrons and they have 6 types : Up quark and Down quark Top quark and Bottom quark Charm quark and strange quark Up quark and Down quark are mostly usual in protons and neutron because they are most stable the others are only produced only wh

Do you know how Microwave oven works???

Image
A microwave oven contains a vacuum tube and the magnetron which gives out heat. The heat is transeferred by electro-magnetic waves which give out heat.   This radiation is fast as it moves in the speed of 2,450,000,000 per second. And so the food is made of hydrogen and oxygen atoms making a molecule and this radiation makes it move and collide each other creating heat inside and outside part of the food.   Now how do we get heat from the microwave ?? The vaccum contains the magnetron and the vacuum gives out electrons making the electro-magnetic waves. It also contains thoruim(good conductor of electricity) and tungsten(good conductor of heat) in its filament also called as cathode and the anode is made of copper and so the electons are bended inside the cavity by the magnetron giving electro magnetic radiation. 

Light from space!!!!

Image
Moonbow A moonbow (also known as a lunar rainbow, white rainbow, lunar bow, or space rainbow) is a rainbow produced by light reflected off the surface of the moon rather than from direct sunlight. Moonbows are relatively faint, due to the smaller amount of light reflected from the surface of the moon. They are always in the opposite part of the sky from the moon. Because the light is usually too faint to excite the cone color receptors in human eyes, it is difficult for the human eye to discern colors in a moonbow. As a result, they often appear to be white.However, the colors in a moonbow do appear in long exposure photographs.

WHAT ARE MITES?

Mites are an extremely successful group of insect-like invertebrates. Their success is due in part to their microscopic size and also to their ability to thrive in a wide variety of habitats. Most mites prey on animals, including mammals, birds, and other insects. Mites rarely transmit disease directly but, because they often cause intense itching, their bites can serve as entry points for infection. In addition to the effects of their bites, mites can cause allergies that affect breathing, like asthma, or the skin, like eczema. Different types of mites have different effects in humans--effects that often resemble other conditions, like contact dermatitis or simple mosquito bites. However what type of mites bite human ?? Mites are tiny arthropods that are related to ticks and chiggers. A majority of mites will never come in contact with human beings, but those that do bite a human can affect that individual's health. Most mite bites cause skin irritation and inten

About Cellular Respiration ....

Cellular Respiration We all need energy to function and we get this energy from the foods we eat. The most efficient way for cells to harvest energy stored in food is through cellular respiration, a catabolic pathway for the production of adenosine triphosphate (ATP). ATP, a high energy molecule, is expended by working cells. Cellular respiration occurs in both eukaryotic and prokaryotic cells. It has three main stages: glycolysis, the citric acid cycle, and electron transport.  Glycolysis:   Glycolysis literally means "splitting sugars." Glucose, a six carbon sugar, is split into two molecules of a three carbon sugar. In the process, two molecules of ATP, two molecules of pyruvic acid and two "high energy" electron carrying molecules of NADH are produced. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. This p

A magnet which is a liquid !!!!

A ferrofluid   is a liquid which becomes strongly magnetized in the presence of a magnetic field. Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields. The magnetic attraction of nanoparticles is weak enough that the surfactant's Van Der Waals force is sufficient to prevent magnetic clumping or agglomeration. Ferrofluids usually do not retain magnetization in the absence of an externally applied field and thus are often classified as "superparamagnets" rather than ferromagnets.

Do you know about levitating frogs!!!!

Image
Levitation is the process by which an object is suspended by a physical force against gravity, in a stable position without solid physical contact. A number of different techniques have been developed to levitate matter, including the aerodynamic, magnetic, acoustic, electromagnetic, electrostatic, gas film, and optical levitation methods.   Animal levitation Scientists have levitated frogs, grasshoppers, and mice by means of powerful electromagnets utilizing superconductors, producing diamagnetic repulsion of body water. The mice acted confused at first, but adapted to the levitation after approximately four hours, suffering no immediate ill effects.

Do you know how your eyes work ?

Eyes are organs that detect light and convert it into electro-chemical impulses in neurons. The simplest photoreceptor cells in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in mollusk, chordates and arthropods.   .

Have you seen corn starch learn how much mess it can make!!!

Image
Corn starch mixed with water in a proper propotion can lead to a substance called oobleck   Oobleck is a non-newtonian fluid. A non-Newtonian fluid is a fluid whose flow properties differ in any way from those of Newtonian fluids. Most commonly the viscosity (resistance to deformation or other forces) of non-Newtonian fluids is dependent on shear rate or shear rate history. However, there are some non-Newtonian fluids with shear-independent viscosity.

Vegetable Battery

Image
The energy for the battery comes from the chemical change in the zinc (or other metal) when it dissolves into the acid. The energy does not come from the lemon or potato. The zinc is oxidized inside the lemon, exchanging some of its electrons with the acid in order to reach a lower energy state, and the energy released provides the power. In current practice, zinc is produced by electrowinning of zinc sulfate reduction of zinc with carbon, which requires an energy input. The energy produced in the lemon battery comes from reversing this reaction, recovering some of the energy input during the zinc production.
