I would like to know if anyone can give me a confirmation on the following:

If you take stainless steel, dissolve it in concentrated HCl to get a green solution, and add excess alkali, the chromium will be the only thing left in solution because it forms a complex while nickel, iron, etc. do not.

Is this true? I have a beaker of HCl eating away at the end of a SS fork as we speak, so if it's possible, I'd like to attempt it.

The final product I'd like is chromium (III) oxide.

And also, I'd like to avoid someone telling me "It's easier to buy your own". This is for the educational purposes, people!

by adding excess alkali will you not get Cr2O3 ?

Telomere length varies among species but not within a species. It also varies with chromosome. So Chromosome 1 of humans will have the same telomere length in all humans but it is different to Chromosome 2.

By your second sentence could I imply that Telomer one would have a different reproduction capacity from Telomer number two ?( also provided that the telomerase might have different activity on different chromosome )

Could I say even the tolomer might be shortened , but the telomerase could also increase the length of the telomer ?

All chromosomes are present in all cells of the body. So the skin cells have the same chromosomes as the nerve cells. The expression of genes (to produce proteins) varies among cells. Comparing nerve cells and skin cells, if a part of one chromosome is expressed in skin cells, it may not be expressed in nerve cells but I think all chromosomes are required for every cell. We cannot pin-point a particular chromosome for a particular organ or system.

I like you answer, Now sense we have all chromosome in the cell would I expect a specific chromosome will express itself to ton a neurons ? And on that chromosome will be the genomes to produce the necessary proteins for the functioning of the cell?

I ask that because each cell of a particular organ is a world of its own and it contribute to that particular organ .

Do all DNA have same length Telomers or it depends on the chromosome type ?

There are 23 sets of chromosome among them, is there a chromosome that is more involved with neurons in the brain functioning ?

Is there a chromosome among the 23 sets that is involved more with the nervous system ?

i mean can you run fast with feet and hands like an animal? because in movies and cartoons humans run like a dog or somthing but would our spine not allow that? just want an opinion maybe with practice?

At the moment I can not give you a reference , but there is a family in Turkey their children have been born with some problem and thy walk and run on four like an animal.
