Hey there!
Life sciences is basically the field dealing with sciences of living beings. There are many subjects in this field, ranging from Zoology, Botany, Biochemistry, Biotechnology, Agricultural sciences, Museology and others. So, when you choose either of the subjects in life science, you major in that subject.
Hence, there is nothing like B.Sc. in Life Sciences.
Rather, it's B.Sc. in Zoology or B.Sc. in Botany and so on and so forth. And further, you mention your field as Life Sciences, while Zoology/Botany is your subject in which you majored.
As for the government jobs, there are many. After a Master's you can get into the research field, obtaining a PhD. There is a lot of opportunity in the research field, its ever expanding.
Apart from that, simply obtaining Bachelors makes you eligible to appear for various governmental examinations like UPSC, Bank exams and others.
Hope this helps. Good luck!
