Q

Which triplet in DNA codes for valine ?
1

A. CTT
B. AGU
C. CAT
D. AAT
E. None of these
A

E. None of these

The triplet in DNA that codes for valine is GTT, GTC, GTA, or GTG.

A triplet is a sequence of three nucleotides in DNA or RNA that codes for a specific amino acid. There are 64 possible triplets, but only 20 amino acids. This means that some amino acids are coded for by more than one triplet. Valine is one of the amino acids that is coded for by four different triplets.

The other triplets listed do not code for valine. CTT codes for leucine, AGU codes for serine, CAT codes for histidine, and AAT codes for asparagine.

The position of earth in its orbit, when it is at its greatest distance from the sun causing northern summer is called ___________?
0

A. Aphelion
B. Perihelion
C. Perigee
D. Apogee
E. None of these
A

A. Aphelion

Aphelion is the point in the Earth’s orbit when it is farthest from the Sun. This occurs around July 4th each year. At aphelion, the Earth is about 94.5 million miles (152.1 million km) from the Sun.

The Earth’s orbit is not a perfect circle, but rather an ellipse. This means that the Earth’s distance from the Sun varies throughout the year. The Earth is closest to the Sun at perihelion, which occurs around January 3rd each year. At perihelion, the Earth is about 91.4 million miles (147.1 million km) from the Sun.

Q

Which of the following layers make radio transmission possible?
0

A. Troposphere
B. Ionosphere
C. Mesosphere
D. Stratosphere
E. None of these
A

B. Ionosphere

The ionosphere is a region of the Earth’s atmosphere that is ionized by solar and cosmic radiation. This means that the atoms and molecules in the ionosphere have lost one or more electrons, giving them a positive charge. The ionosphere is located between 50 and 1,000 kilometers above the Earth’s surface.

The ionosphere is important for radio transmission because it reflects radio waves back to Earth. This allows radio waves to travel long distances around the Earth. Without the ionosphere, radio waves would travel in a straight line and would not be able to reach distant locations.

Q

Monsoon is caused by____________________?
0

A. Seasonal reversal of winds
B. Revolution of earth
C. Movement of clouds
D. Rise in temperature
E. Rain forests
A

A. Seasonal reversal of winds

Monsoons are seasonal changes in the direction of the prevailing winds. They are caused by the differential heating of land and water. During the summer, the land heats up faster than the ocean, causing the air over the land to rise. This creates a low-pressure area over the land, which draws in moist air from the ocean. This moist air rises and cools, forming clouds and rain.

During the winter, the land cools down faster than the ocean, causing the air over the land to sink. This creates a high-pressure area over the land, which pushes the moist air out to sea. This results in dry weather over the land.
