BCA

After BCA, you should go for MBA in IT.

M.Sc. is good to become a teaching faculty.
If you want to join as a professor in private college than I suggest you to select MCA because there are so many college of MCA and they hire MCA students as BCA faculty.
B.Ed. is also a good option but first check that your state government hires computer teachers in government schools or not. If yes the do B.Ed.
M.Sc. in IT and MCA, both are applied subjects, so both have same market value but it's my personal suggestion that MCA is beneficial. After this, prepare for NET examination to get job in a government college as an associate professor.

Yes, of course you can. A graduation degree from any of the recognized university is the only prerequisite to pursue MBA. Of course the university criteria vary. If you would like to pursue correspondence MBA online, National Institute of Business Management (NIBM) can be a good option. NIBM offers one year MBA, two year MBA and one year Executive MBA in online mode. NIBM also offers online MBA video tutorials to all its registered students.

You must choose biotechnology as it is a noble and respectful career and will offer a better salaried job. Thus, it is better and you should go for it.
