Hotness of Chilli Pepper is measured in which unit?
The Scoville scale is a measurement of the pungency (spiciness or "heat") of chili peppers and other spicy foods, as recorded in Scoville Heat Units (SHU) based on the concentration of capsaicinoids, among which capsaicin is the predominant component. The scale is named after its creator, American pharmacist Wilbur Scoville, whose 1912 method is known as the Scoville organoleptic test. The Scoville organoleptic test is the most practical method for estimating SHU and is a subjective assessment derived from the capsaicinoid sensitivity by people experienced with eating hot chilis.
An alternative method, using high-performance liquid chromatography (HPLC) can be used to analytically quantify the capsaicinoid content as an indicator of pungency. As of 2011, the subjective organoleptic test has been largely superseded by analytical methods such as chromatography.

What is Web 3.0, Web 2.0 and Web 1.0 ?
Web 3.0 is a term that is used to describe many evolutions of web usage and interaction among several paths. In this, data isn’t owned but instead shared, where services show different views for the same web / the same data.
The Semantic Web (3.0) promises to establish “the world’s information” in a more reasonable way than Google can ever attain with their existing engine schema. This is particularly true from the perspective of machine conception as opposed to human understanding. The Semantic Web necessitates the use of a declarative ontological language like OWL to produce domain-specific ontologies that machines can use to reason about information and make new conclusions, not simply match keywords.
Web 2.0 refers to worldwide websites which highlight user-generated content, usability, and interoperability for end users. Web 2.0 is also called the participative social web. It does not refer to a modification to any technical specification, but to modify the way Web pages are designed and used. The transition is beneficial but it does not seem that when the changes occur. Interaction and collaboration with each other are allowed by Web 2.0 in a social media dialogue as the creator of user-generated content in a virtual community. Web 1.0 is an enhanced version of Web 2.0.
Web 1.0 refers to the first stage of the World Wide Web evolution. Earlier, there were only a few content creators in Web 1.0 with a huge majority of users who are consumers of content. Personal web pages were common, consisting mainly of static pages hosted on ISP-run web servers, or on free web hosting services.

How do Spiders make Web?
Spiders produce silk threads to build their webs.
The silk is produced in silk glands with the help of the spider's spinnerets. Spinnerets are special organs that allow the spider to decide what type of thread it needs for the web.
The silk threads can be thick or thin, dry or sticky, beaded or smooth. The threads a spider uses to construct its web begin as liquid, but they dry quickly in the air.
When a spider begins a web, it releases a silk thread. It anchors the thread to some object — a branch, a corner of a room, a doorframe — wherever it builds its web.
As the spider moves back and forth, it adds more threads, strengthening the web and creating a pattern. Lines that go from the center of the web outward are called "radial lines." They support the web. Threads that go around and around the web are called "orb lines."
When a spider catches prey in the sticky strands of its web, it approaches the trapped insect and uses its fangs to inject venom. The venom either kills or paralyzes the prey, allowing the spider to enjoy its dinner in peace.
Not all spiders use webs for food, however. Some don't build webs at all. Other spiders chase their prey. Some even make sticky nets, which they throw over their prey when it gets close enough.

How Long Can a Cockroach Live Without Its Head?
Even for major catastrophes like losing a head, cockroaches don’t bleed very much. Unlike humans, they have an open circulatory system: A system for distributing blood through their bodies that doesn’t depend on a closed network of arteries and veins. Their blood doesn’t pump under pressure like ours, but just sort of sloshes around, making its way into the cockroach’s tissues.
The great thing about this system, if you’re someday going to be headless is that when a major wound occurs, blood doesn’t suddenly get forced out. For a cockroach that loses its head, the blood just clots at the neck. The cockroach will have a nasty scab for sure (where its head used to be), but it won’t die from loss of blood.
Unlike humans, cockroaches don’t breath through a nose or their mouth. Instead they breathe through small holes in their bodies called spiracles that don’t need a brain to direct them. No nose, no mouth, and no need for a brain to regulate your breathing means that you can breathe all you want to without a head.
But it is going to die from being unable to eat. And well before that, it’s going to die from thirst. A headless cockroach has no mouth to drink with and will be dead from dehydration in less than a week. Which brings the total day count from the moment it loses its head to the moment it loses its life to somewhere around 7 days or less.

What is Black Box?
The Black Box or Flight Data Recorder of an Airplane is an instrument which records all the activities of the airplane during its flight. From the security point of view, this box is generally kept at the back side of the airplane. This Box is made of Titanium metal and is enclosed in a Titanium box which gives it strength to withstand any shock if it falls in sea or falls from the height. It can work for 30 days without any electricity. It can withstand a temperature of 11000°C. When this box is lost anywhere, it keeps on emitting the waves along with a beep sound for about 30 days. This voice can be identified by the investigators from a distance of about 2-3 Kilometers. An interesting fact with regard to Black box is that it can emit waves from the depth of 14000 feet in the sea.
