The point within the Earth where earthquakes originate is _________?
		A. Comma
B. Origin
C. Epicenter
D. Focus
		A. Comma
B. Origin
C. Epicenter
D. Focus
Afternoon rains in the equatorial region are the result of influences _______?
		A. Land Breeze
B. Monsoon
C. Frontal
D. Convectional
		A. unicellular
B. multicellular
C. acellular
D. none of these
Viruses are nor unicellular neither multicellular the are acellular organisms means without cell configuration. Actually they are only made up of nucleic acid and proteins. Viruses are acellular biological entities made up of nucleic acid and proteins. The nucleic acid is either DNA or RNA; both are never found together in a virus. Thus viruses are neither unicellular nor multicellular.
Fog that most often forms as warm rain falls into a cold layer of surface air is called ______________?
		A. Radiation fog
B. Evaporation (mixing) fog
C. Advection fog
D. Upslope fog
___________are negatively (-) charged particles of an atom?
		A. Protons
B. Neutrons
C. Electrons
D. None of These
		A. Speed
B. Frequency
C. Intensity
D. Wavelength
Sound is propagated in the form of longitudinal waves. When sound travels from one medium to another medium the wavelength and velocity remains changed and the frequency remains unchanged.The velocity of sound in the given medium is obtained by
v=nW, where “n” is the frequency of sound and “W” is its wavelength in that medium. Velocity of sound is directly proportional to the wavelength.Thus, if the velocity of sound wave doubles when travelled from one medium to another medium then its wavelength also doubles.The frequency of sound depends on the source of the sound, not the medium of propagation .Hence the frequency does not change when travelled from air to water.
		A. Dwarf Planet
B. Gaseous Planets
C. Terrestrial Planets
D. Both A & B
The planets Mercury, Venus, Earth, and Mars, are called terrestrial because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.
