It makes it easier to communicate and understand measurements because they do not need to be converted from one unit to the other and the measurement of each object changes depending on which units are being used.
Explanation:
Having a standard set of units amongst all scientists helps because when they measure data using different types of equipment, the units may be different, so having a standard set of units allow them to be able to have the same unit to work with and use among each other :)
Once a person has developed mumps they remain immune to that disease for the rest of their lives. Therefore if they come in contact with the virus again their immune system recognises the virus and eradicates it. To improve your immune system you can eat healthy and exercise often.
