The largest circular storm in our solar system is on the surface of which of the following planets?
Jupiter
Why doesn't the planet Uranus explode if it contains so much hydrogen and methane?
The planet Uranus indeed contains a significant amount of hydrogen and methane, both highly flammable gases. However, the burning of methane or hydrogen requires oxygen. Simply put, there is no free oxygen on the planet Uranus.
What is the anti-matter equivalent of an electron?
Positron
Human CNS is composed of ...
Brain and the Spinal Cord
Ozone hole refers to...
Decrease in the thickness of the ozone layer in stratosphere
The rapidly moving stream of charged particles that is being driven away from the sun is known as what?
Solar Wind
How does dissolving a salt molecule in water make its atoms ionize?
Dissolving a salt molecule in water does not make its atoms ionize. The atoms in solid salts are already ionized long before touching the water. As a result, electrons in an atom take different states, starting from the lowest energy state and going upwards in energy until the electrons have all found distinct states.
Why is the sky blue?
As white light passes through our atmosphere, tiny air molecules cause it to 'scatter'. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day.

The biggest asteroid known is:
Ceres
How do plants get their nitrogen from the air?
Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes.
When light bends as it enters a different medium the process is known as what?
When light bends as it enters a different medium the process is known as Refraction.

Pineal Gland
Plants receive their nutrients mainly from ...
The soil
Rounded to the nearest day, the Mercurian year is equal to:
88 days
Are two atoms of the same element identical?
No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
Electric resistance is typically measured in what units?
Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
Who discovered the base for neurotransmittion?
Otto Loewi
Movement of cell against a concentration of gradient is called ...
Active transport
The time interval between two successive occurrences of a specific type of alignment of a planet (or the moon) with the sun and the earth is referred to as:
A Syndonic Period
