Test how good you are at your science quotient with our new Science Quiz!

Q1.X is a nuclear medicine, functional imaging technique that produces a three-dimensional image of functional processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Three-dimensional images of tracer concentration within the body are then constructed by computer analysis.Identify X.

Ans.Positron Emission Tomography (PET scan)

Q2.Gas masks with adsorbent filters,Explosives,fumigants,mustard gas are credited to which famous person also known as "Father of Chemical Warfare".He is also behind one of the most famous industrial processes for manufacturing a certian chemical.Identify the man.

Ans.Fritz Haber

Q3.X is a lightweight, extremely strong and robust material, and is used for many products. Although its strength properties are somewhat lower than carbon fiber and it is less stiff, X is typically far less brittle, and its raw materials much less expensive. Its bulk strength and weight properties are also very favorable when compared to metals, and it can be easily formed using molding processes.Common uses of X include high performance aircraft (gliders), boats, automobiles, bath tubs and enclosures, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, casts, surfboards and external door skins.This substance is gaining popularity with its wide usage.Identify.(image follows)

Ans.Fiberglass

Q4.X originated from Swahili word,Kadingapepo,which refers to evil spirits.It also is said to originate from Spanish for fastidiousness,which the patients experience.Identify X,a famous disease.

-From scabs,as the body is completely covered with scabs.

Ans.Scurvy

Science Quiz #1

Q1 .
Id X.
X investigated the gastric function of dogs, and later children,^[15] by externalizing a salivary gland so he could collect, measure, and analyze the saliva and what response it had to food under different conditions. He noticed that the dogs tended to salivate before food was actually delivered to their mouths, and set out to investigate this "psychic secretion", as he called it. X laboratory housed a full-scale kennel for the experimental animals. X was interested in observing their long-term physiological processes. This required keeping them alive and healthy in order to conduct chronic experiments, as he called them. These were experiments over time, designed to understand the normal functions of animals. This was a new kind of study, because previously experiments had been “acute,” meaning that the dog went through vivisection and was ultimately killed in the process

Ans. Pavlov

Q2.Picture of?


                               



















Ans. The islamic Globe

Q3.
Albert Einstein quoted about the importance of X-
"If X disappeared from the earth, man were to live only for four years"
The reason cited was : As to X and humans. About 35% of our food supply are from plants pollinated by X, birds and bats; and we can expect that those food products would be less available. Therefore the survival of X is important.
What is X ?


Ans. Honey Bees

Q4.

Ans Gravitational Pathways

Q5.
What is the formula calculating? 
   

Ans. Magnitude of Earthquake 

Q6. What effect is the water droplet experiencing here?
