This type of matter has a definite volume but no definite shape... A: Solids, B: Liquids, C: Gases, D: Plasma
What is B: Liquids. Liquids have a definite volume but no definite shape. Because the intermolecular forces are weak in a liquid, it is able to change its shape to conform to its container.

If electrical conductivity increases with the increase of temperature of a substance, then it is a:

A. Conductor   B. Semiconductor

C. Insulator D. Carborator

What is B: semiconductor. A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. Its resistivity falls as its temperature rises

Of the following, it has the longest recorded life span. A: Termite, B: Chimpanzee, C: Indian Elephant, D: Freshwater Oyster
What is the Freshwater Oyster (80 years.) The longest recorded life span for a termite is 50 years; for a chimapanzee, 50 years; and for an Indian elephant, 70 years.
300

This type of water weighs the most... A: seawater B: distilled water C: tap water D: none - They all have the same weight.

What is A: sea water. It is loaded with mineral salts and weighs about a pound and a half more per cubic foot than fresh water at the same temperature.

300
Matter that does not enter chemical reactions is described as this... A: Inhibited, B: Inert, C: Grounded, D: Radioactive
What is B: Inert. Inert matter does not enter chemical reactions.
300

It is the sound of frequency below 20 Hz 

A. audio sounds B. infrasonic 

C. ultrasonic D. supersonics 

What is B: Infrasonic. Sometimes referred to as low status sound, describes sound waves with a frequency below the lower limit of human audibility.

This was the first genetically engineered organism. A: Corn, B: Tobacco, C: Sheep, D: Rat
What is a B. tobacco plant. In 1983, a tobacco plant, designed to be resistant to certain herbicides, was grown in Wisconsin.
400
It is the term for the condition when three celestial bodies are arranged in a straight line... A: Occultation, B: Parallax, C: Syzygy, D: Triple Transit
What is C: Syzygy. Syzygy is the condition when three celestial bodies are arranged in a straight line--as, for example, when the Sun, Moon, and Earth are aligned during solar and lunar eclipses.

The natural phenomena which one known in Sanskrit as 'deer's thirst'?

A. Rainbow B. Earthshine C. Halo D. Mirage 

What is D: Mirage.  A naturally occurring optical phenomenon in which light rays bend via refraction to produce a displaced image of distant objects or the sky.

This animal has the highest blood pressure... A: Giraffe, B: Blue Whale, C: Elephant, D: Flea
What is A: Giraffe. Because of its extremely long neck, the giraffe must rely on its oversized heart (two feet long and twenty-five pounds!) to pump blood all the way to its head. As a result, the giraffe has the highest blood pressure of any animal: 280/180 mmHg (millimeters of mercury) at heart level when prone -- more than twice the blood pressure of an average human. Not surprisingly, because of their high blood pressure, giraffes are prone to heart attacks.

This is the hardest naturally occurring substance... A: emerald B: tourmaline C: diamond D: corrundum

What is C: Diamond. Diamond is also one of the most valuable natural substances. Diamonds are crystals formed almost entirely of carbon. Because of its hardness, the diamond is the most enduring of all gemstones. They are among the most costly jewels in the world, partly because they are rare, Only four important diamond fields have been found - in Africa, South America, India, and the Soviet Union.

These are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodesic dome... A: Hydrocarbons, B: Lipids, C: Crystals, D: Buckyballs

What is D: Buckyballs. "Buckyballs" are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodosic dome. Also called fullerenes or buckminsterfullerenes, they were named after R. Buckminster Fuller who invented the geodosic dome. Buckyballs are of great interest to scientists because they contain a cavity large enough to hold other elements, even whole molecules. Once an element has been deposited into the cavity, it cannot emerge without being heated to high temperatures. This technology may someday be used to deliver medication to specific locations within the body.
