Ohhh so it was misspelled ... in the case of being "sweat" the answer is sodium chloride. It also contains smaller amounts of methylphenol

Let's pray that your answer sponge is right
I recall a joke according to the situation

Dad : Beta ye dua kiyoon mang rahay ho
Boy : Main paper main likh aaya hun Japan Pakistan ka capital hay

yup steel is more elastic than sponge :
Elasticity is the capability of an object to return to its former shape once a load inducing strain is removed. If you were to drop a steel ball on a very hard surface, it would probably bounce higher than than rubber. If you drop it on a softer surface, because it would deform less, then the surface it is to bounce off will be the one deforming, so the bounce would be a function of the elasticity of the floor, not of the ball.

A strand of silk is indeed stronger than a steel wire of the same diameter. The reason is that metal uses metallic bounds which is not as strong as the covalent bounds in a macro-molecule like the ones in silk. This also explains why Kevlar, carbon fiber, and carbon nanotubes are also stronger than steel.

Youngs Modulus of steel is more than youngs modulus of rubber

I have already made provision for that. It has been my practice in my life when I am uncertain about any thing I park it in loss category. So I did not count any question in my expected lot of which I had uncertainty.

Asslamulaikum,

I wish all of you people Good luck, who appeared and solved this paper.

The easiest paper I have ever seen, though MCQ's from Geology, Biology, Chemistry, Physics are all present yet very easy.
I will be having the Solutions in the next post.

Regards..

Dear jtalpur, its reason is the fact that parents are ''heterozygous'' meaning each of them[parents] have one allele for the disease. so when u do the cross bw such parents the ratio comes out is 25 % or 1/4. u can understand this concept if u know how to make a cross bw traits.
Suppose a person has 't' allele for diabetes, 'T' [capital] for normal. one parent has 'Tt' and the other likewise has 'Tt' , now then cros [Tt into Tt] and make its possible subsets like this : TT, Tt, tT, tt. in this configuration u can see the letters ''tt'' stands for the disease and its ratio is 25% , therefore it is 1/4 .
hope this concept is clear enough for you.

little correction: alleles tt stands for diabetes, all others options like Tt,tT,TT, are for normal. Tt option is heterzygous normal.
