Scientific notation is especially useful if you use very large numbers, or very small numbers (numbers close to zero). I am not sure whether biologists commonly use such numbers, though.

You can't. There is a minimal amout of words (and names) that you can use numbers to spell.

Yes, you can use characters other than letters and numbers in sheet names.
