dear frinds
i am not an aspirant of css as i am searching this forum for the nab jobs being over aged 32 years of age. I cam across an objective MATER AND ENERGY can be converted into each other there were four options so i just decided to share my knowledge it may be right or wrong. but it is my idea

the relationship of energy and matter is given by the eienstine equation E=MC SQUARE this states that the matter and energy are changeable from one state to another but he also stated that the matter can be changed into energy but energy cannot be changed back into the matter. its my point of view
pardon me if i am wrong

and the answer of that objective is NONE OF THESES

Dear!

I regret, but it is my painful duty to inform you that your postulate is wrong. Energy and matter are interchangeable. When nucleus is broke up into its particles (by adding/bombarding it with high energy rays called as Energy Defect) then total mass of seperated particles taken alone is more than the parent nucleus. The energy of the rays is added up as mass to the divided particles increaing its mass.

Conversely, when sub-nuclear particles are added up to again form the nucleus then some amount of energy is released and the resultant nucleus is less in mass than the total sum of mass of individual particles that made up that nucleus.

Hope this explanation would help you get my point.

Dear Amir!

I think it should be option A because, besides the minor gramatical error, rest of the statement of this option seems to be comprehensive and logical.

Now comes the second part, here also 23 hour and 56 minute approximately are equal to 24 hour and that is what we hear everyday. (as it was Everyday Science paper :-) ).

Besides all this, I appreciate that you pinpointed very minor details of MCQs.

yar for hormones u can consult any book of physiology eg guyton or ganong physiology. even on google just insert steroid hormones u vl get ample info. for energy yielding biochemistry eg lippencot. or net. for deafness ent by dhingra. :huh:huh:huh and onething more dTMP z the monomer of DNA nt dGTP it z a energy molecule so ans z dTMP. need refernce for this?:):):):):):)

dear niazi dGTP...which is Deoxyguanosine triphosphate is component of DNA. it is one of 4 nitrogenous basis used for DNA synthesis.the other three are adenine,thymine,cytosine.these four bases+deoxyribose sugar and phosphate group join to form DNA double helix.

prokaroytes posses none of these structures.all the three organelles are membrane bounded and prokayotes have no membrane bounded structure.
so the answer was D(none of these)
