Which triplet in DNA codes for valine ?
1
A. CTT B. AGU C. CAT D. AAT E. None of these
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.

Which of the following layers make radio transmission possible?
0
A. Troposphere B. Ionosphere C. Mesosphere D. Stratosphere E. None of these
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.

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. 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.

C. A
D. B
A. O
A person with blood group O is called a universal donor because their blood can be given to people of any blood group. This is because blood group O does not have any antigens on the surface of the red blood cells. Antigens are proteins that can trigger an immune response if they are not compatible with the recipient’s blood group.
Blood group O is the most common blood group, with around 45% of the population having this blood group. Blood group AB is the rarest blood group, with only around 4% of the population having this blood group.
