Any correction is more than welcome !!!

Take care,

@ sohail shujaWell, i think that u are mixing the concept of chromosome with the gene here. A chromosome is a helical structure normally appears as threads. On the other hand, u might have added that it is basically composed of four proteins in different combinations. The proteins are : Adenine, cytosine, guanine and thymine.

@ impossible
Well, i personally think that it is not a general process of reproduction, the more precise reply would be "mitosis", through which, the cells make thier exact copies.

Well, these are the corrections I could suggest wth the very best of my knowledge.

Well, it would be really nice if u would have answered it as "Clinical Thermometer"

Well, here agin, NTP is a vaguer term for "Natural Temperature Pressure", it is usually taken as STP in the scientific descriptions. Since "Network Time Protocol" appears to me a more relative term.

@yasir

salam
u r right there about MITOSIS.
well done explained very well.

Wsalaam

Thanks for the appreciation buddy. But i think that Sohail Shuja deserves somewhat a compliment from me for his prolific, though a slightly inaccurate effort.

Well Done Sohail Shuja

IN QUSTION NUMBER 7, PART 6 OF eds 2006, DO U THINK THAT YOU HAVE FOLLOWED THE LAPLACE RULE, ACCORDING TO WHICH SOUND SPEED IN MEDIUM IS INVERSELY PRPORTIONAL TO SQUARE OF DENSITY SO I THINK IT SHOULD BE FALSE.
WHAT YOU SAY IS AIR MORE DENSE OR IRON SO...? WELL DO TELL
take care Hafiz

WELL sba nice query..... here is logical explanation for my answer... this may also be experienced on a railway track practically..
The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties which effect wave speed - inertial properties and elastic properties. The density of a medium is an example of an inertial property. The greater the inertia (i.e., mass density) of individual particles of the medium, the less responsive they will be to the interactions between neighboring particles and the slower the wave. If all other factors are equal (and seldom is it that simple), a sound wave will travel faster in a less dense material than a more dense material. Thus, a sound wave will travel nearly three times faster in Helium as it will in air; this is mostly due to the lower mass of Helium particles as compared to air particles.

Elastic properties are those properties related to the tendency of a material to either maintain its shape and not deform whenever a force or stress is applied to it. A material such as steel will experience a very small deformation of shape (and dimension) when a stress is applied to it. Steel is a rigid material with a high elasticity. On the other hand, a material such as a rubber band is highly flexible; when a force is applied to stretch the rubber band, it deforms or changes its shape readily. A small stress on the rubber band causes a large deformation. Steel is considered to be a stiff or rigid material, whereas a rubber band is considered a flexible material. At the particle level, a stiff or rigid material is characterized by atoms and/or molecules with strong attractions for each other. When a force is applied in an attempt to stretch or deform the material, its strong particle interactions prevent this deformation and help the material maintain its shape. Rigid materials such as steel are considered to have a high elasticity (elastic modulus is the technical term). The phase of matter has a tremendous impact upon the elastic properties of the medium. In general, solids have the strongest interactions between particles, followed by liquids and then gases. For this reason, longitudinal sound waves travel faster in solids than they do in liquids than they do in gases. Even though the inertial factor may favor gases, the elastic factor has a greater influence on the speed (v) of a wave, thus yielding this general pattern:

vsolids > vliquids > vgases
