​​What is TestTube Baby?😲🤔🤔🤔🤔

In a normal pregnancy, a male sperm penetrates a woman's egg and fertilizes it inside her body after ovulation, when a mature egg has been released from the ovaries. The fertilized egg then attaches itself to the wall of the uterus, or womb, and begins developing into a baby. This is known as natural conception. However, if natural or unassisted conception is not possible, fertility treatment is an option. IVF has been used since the late 1970s. On 25 July 1978, the first "test-tube baby," Louise Brown, was born. Robert Edwards and Patrick Steptoe, who collaborated on the procedure, are considered to be the pioneers of IVF. It involves fertilizing an egg outside the body, in a laboratory dish, and then implanting it in a woman's uterus. By 2016, some 6.5 million babies had been born using in-vitro fertilization (IVF). According to the Centers for Disease Control and Prevention (CDC), around 1.6 percent of babies born in the United States each year are conceived throug...

​​Why do Mosquito bites itch?🤔🤔🤔🤔

​​Why do Mosquito bites itch? While bees and wasps inject venom when they sting, mosquitoes simply bite to feed on your blood.

We should apply these materials on mosquito bite... 

How and why do fireflies light up?🤔😱

Fireflies produce a chemical reaction inside their bodies that allows them to light up. This type of light production is called bioluminescence. The method by which fireflies produce light is perhaps the best known example of bioluminescence. When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced. Unlike a light bulb, which produces a lot of heat in addition to light, a firefly's light is "cold light" without a lot of energy being lost as heat. This is necessary because if a firefly's light-producing organ got as hot as a light bulb, the firefly would not survive the experience. A firefly controls the beginning and end of the chemical reaction, and thus the start and stop of its light emission, by adding oxygen to the other chemicals needed to produce light. This happens in the insect's light organ. When oxygen is available, the light organ lights up, and ...

(7).How Does Gorilla Glass Work?

. How Does Gorilla Glass Work? Gorilla Glass is a special kind of glass created by Corning Inc that is used in electronic devices such as smartphones, tablets, and television screens. The type of glass Corning creates for their Gorilla Glass is aluminosilicate. This sort of glass is sand-based and is made up of aluminum, silicon, and oxygen. After the initial glass is created, the product is placed in a molten salt bath that's over 400 degrees Celsius. This heat triggers an ion-exchange process that forces the smaller sodium ions out of the glass and replaces them with larger potassium ions drawn in from the salt. This process of packing larger ions into the same sized space makes the glass significantly denser than it was originally. This is what gives Gorilla Glass its strength and flexibility. The first generation of Gorilla Glass was created in 2008 with additional iterations produced in 2012, 2013, and 2014. The fifth generation of Gorilla Glass was released in July, 2016 for ...
