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.

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.

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.

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 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.

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.

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.

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.

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.
