I am sure that some scientists and engineers use it for some of their work.
The scientist would not.
First you would need to have qualifications to prove that you are an Excel expert. Microsoft and other bodies provide such qualifications. To get a job purely based on being an Excel expert would not be easy. Many jobs can use Excel, so you may also need other qualifications, like accountancy, to get into one of those jobs. If you were an accountant, you could be using Excel a lot, so being an expert in it would be very useful. Another kind of job could be training people how to use Excel. To do that you would also need training qualifications and you would need to know other subjects so that you could train people on more than just Excel. There are many other jobs like that where you would need to be qualified in other areas and having Excel expertise would be a bonus.First you would need to have qualifications to prove that you are an Excel expert.

No, Excel is not part of the Works Suite 2005. It has its own spreadsheet in it and it is like Excel. It will do the vast majority of the things you would need to do.

We use symbols in excel when we need to add a symbol of copyright, trademark symbols, and Unicode symbols etc.
you need scientist because without them how would we have rockets or any technology
You wouldn't need a scientist of any particular specialty to build a device.
You would first need to know how the fat in milk is calculated and have a formula for it. You would need to know what values are needed to do it. Then you would need to get the values you need and enter them into cells in the spreadsheet. Using these cell references to build your formula, you could do the calculation.
They would not need to know all functions, but they would need a good general knowledge of Excel's functions, beyond an ordinary user. Depending on the kind of developing they are doing, they may need to be particularly familiar with some categories of functions. For example, they may need a particular familiarisation with financial functions if they were developing for financial spreadsheets in Excel.
That will depend on what you want to do. If you are in Excel saving as a standard Excel file, you don't need to change the file type. It is only if you want to save into a different format, that you would change the File Type. What you change it to, would depend on what you need. You might want to change to a different version of Excel or maybe into a completely different format, such as a text file. If you are working in a different application, saving something to be used in Excel, then again it will depend on what format you actually need.
It would be a group of cells in Excel that have values in them. These can then be identified for use in creating charts in Excel. Different charts need data series for them to show.
That depends on the version of Excel. Up to Excel 2003 it would be A1:IV65536. From Excel 2007 onwards it would be A1:XFD1048576.
