I guess may be it has on significance !alcohol is not so good to taste n just to get good taste they eat things !not sure

In hybridoma technique ..why do v need to kill so many mice ,cant v think of any other way in which v can obtain products without harming those animals ? Cant v use humans for this ,like instead of inducing cancer in those animals cant v take cancer cells from an affected person n lymphocytes from the spleen of a dead person who had the infection ??is there any problems if v use humans for this ?(except ethical issues)i just thought of it coz if v can use mice for this then i guess v wont have much problems with human cells!sorry if i am wrong ! I just posted what i think !(i dont know much about this technique,)

I don't know if im wrong.In some way even genes are responsible for ugliness. ugliness is determined by eye shape,skin colour,nose positioning, short stature etc and these are determined by genes and can be tranfered from parents to offsprings.

If a mother is hemophilic-A and father is hemophilic-B then what type of hemophilia the daughter may suffer from ?

"Another possible explanation for this would be if the father had Klinefelter's syndrome.This means he would be a "XXY" male, so instead of a 50% chance it would be a 66% chance in favour of female offspring, or odds of 624999:1 for this same situation occurring". -Originally posted by Trox Do cats get Klinefelter's syndrome? Even if they get can that cats be abe to produce sperms?(even if they do ,does meiotic non-disjunction always occur in them so that no Klinefelters is born again? )

Thank you timo ,from next time onwards i will keep this in my mind .I checked the original question but that is same as the question i typed. I wanted to add my calculations but i didn't know how to type the root ,from next time i will add my calculations.

Please guide me in solving this problem:Find 'n' in the unit vector 1/10(4 icap+8 jcap+n kcap). The answer at which I arrived is root 20 but the one given in the book is root 0.002 .Please tell me if I am correct and if i am wrong guide me in solving this problem.

During the course of evolution if more complex animals are formed (than man), can their requirement of essential amino acids decrease? Can their body adapt itself to produce these essential amino acids?

Then why some amino acids are called semi essential?

Thank you for your help. This was a 2-mark problem for 10th standard student. I just split the expressions and the final answer I got was 2\sqrt 7. Please tell me whether I am correct in my approach.

I am a pathologist 's daughter trying to help my friend. please help me to find the answer.

Exciting images and discussion too.

If all heavenly bodies arose from a unit mass after big bang why the planets in our solar system differ in their composition?

Thanks for the tolerance.

I was surprised to know that it's not a biologist but an astronomer - George Gamow - in 1954 proposed the three letter word to pick aminoacids during protein synthesis. I am curious to know what might be the logic behind this proposal which was proved to be right later? I am looking for a mathematical answer. I am a high school student. Please enlighten me.

Actualy what I mean by "properly as humans" is comparing it with humans.

Actualy I remember reading that after sun becomes a red gaint first mercury will go inside the sun then venus. After that earth will be the first planet, the heat from the sun destroys everything on earth. Then eventualy all planets will go, then after some million years our sun will become a supernova, then a dwarf star and afert some years it will disappear. As I know this is the end of our sun. It takes 8minutes and 10seconds for the linght to reach earth form the sun.

Why gravity is always atractive. Why there is no repulsion?

Are bats considered as link between nocturnal animals and animals who can see proparly as humans in evolution ? As bats have eyes but can't see ,what is their place in evolution ? I am a high school student plesae clarify .

Do all planets have magnetic field? What determines the strength of the magnetic field.
