These are the only two planets in our solar system without moons... A: Mercury & Venus, B: Venus & Mars, C: Uranus & Neptune, D: Neptune & Pluto
What is A: Mercury & Venus. As far as we know, Saturn has the most moons. Saturn has at least 25 satellites that measure at least 6 miles (10 kilometers) in diameter, and several smaller satellites. The largest of Saturn's satellites, Titan, has a diameter of about 3,200 miles (5,150 kilometers) -- larger than the planets Mercury and Pluto.

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.

This is created when electrons move through a wire... A: current B: charge C: cell D: proton

What is A: current. Current is defined as the rate of flow of charge passing a point.

This living animal has the heaviest brain... A: African Bush Elephant, B: Black Rhinoceros, C: Sperm Whale, D: Human
What is C. Sperm Whales. They have the heaviest brain of any living animal. The average Sperm Whale's brain weighs more than 20 pounds (9 kilograms) which is about 4 times heavier than the average human brain.

This year boasted the first woman in space... A: 1963, B: 1968, C: 1973, D: 1983
What is A. 1963. The first woman in space was Valentina Vladimirovna Tereshkova in Vostok 6 (U.S.S.R.).

This is the type of bond where atoms share electrons.. A: Aerobic Bond, B: Soul Bond, C: Ionic Bond, D: Chemical Bond

Who is C: Ionic Bond. 

200

This is the unit of energy... A: Watts B: Coulombs C: Power D: Joules

What is D: Joules.

300
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
The three main parts of a comet are the nucleus, the tail, and the _____. A: Zenith, B: Umbra, C: Radiant, D: Coma
What is D. Coma. The coma consists of gases and dust around the nucleus.
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

This would steal the most electrons when rubbed against hair... A: gold B: wood C: diamond D: plastic

What is D: Plastic. Plastic is the best insulator listed, and that means that when rubbed against someone's hair it will steal the most electrons.

400
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.
400
These substances control the rates of chemical reactions... A: Reactants, B: Catalysts, C: Isotopes, D: Cathodes
What is B: Catalysts. Catalysts are substances that control the rates of chemical reactions.
400

A component of a circuit that is designed to melt and causes a break in the circuit when the current is too high ... A: heating element B: resistor C: diode D: fuse

What is D: fuse. The old style of fuse melted, making a gap in the circuit, but the new style is a switch that is run by magnets.

500
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.
500
The planets make up this percentage of the mass in our solar system... A: 0.0135 %, B: 0.135 %, C: 1.35 %, D: 13.5 %
What is B: 0.135 % of the mass in our solar system. The Sun dominates, accounting for 99.86 % of the entire solar system's mass.
500
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.
