well according to internet I also found the answer jupiter but in books like kashmire its saturn. yet I believe the net would be updated.

"Echo does not add to the original sound as reverberation does" you may will find this statement in below link.

Still confused about reverberation as in wikipedia it is also written that reverberation is the reflection of sound after removing original sound. Echo is also not up to the mark but if the answer is not NONE OF THESE what it is the most
accurate one. The link you provided also does not clarify it.


Definitely Vitamin C is needed in small amount it also acts as antioxidant in body. Actually all the sugars (carbohydrates) are ultimately converted into monossacharides. More than 80% of energy that we use comes from burning of monossacharides in the body.

And the last thing haematite and magnetite are not iron oxides these are IRON ORES not oxides

Question # 03: What do you know about hereditary disease ? Comment how they are transferred from parents to offsprings ? (10)
A hereditary disease is that which is passed from parents to their offspring.For example AIDS is passed to offspring if a mother suffering from AIDS gives birth to a baby.
Many hereditary diseases are passed on within families from one generation to the next. Just as children may inherit normal features such as brown eyes or curly hair from one or both parents, children can also inherit certain disorders. Whether or not a specific trait or disorder is inherited is determined by hereditary material called "genes." Genes are the units of hereditary material. They contain coded instructions which direct the development of every cell and tissue in the human body.( You might think of genes as blueprints, specifying how the body will develop and function.)
Just for information guys i have added this:
Thousands of genes are found on thread-like structures, called chromosomes, which are located in the center or "nucleus" of each cell. Genes and chromosomes exist in pairs. At the time of conception, each parent contributes one gene and one chromosome from each of his or her gene and chromosome pairs. The genes and chromosomes from each parent combine into new pairs which determine the traits a child inherits.

Most often, genes produce normal traits. Sometimes, however, a gene becomes altered from its original form. A gene that is thus changed is called a "mutant" gene. Although researchers know that mutations occur, the reasons for their occurrence is not completely understood. Some mutations are not harmful, but most often a mutant gene functions improperly and causes a disorder, malfunction, or malformation within the body. Mutations can occur in any generation. If a spontaneous mutation occurs, it is then possible for a child to be the first family member to get a genetic disorder such as Marfan syndrome, even though both parents are normal.
Many common diseases can be caused by mutant genes. In many cases, you can manage some of those diseases just by keeping fit and staying healthy.
