Is there any black African who has made a scientific invention or discovery worthy of a nobel prize?

Answer 1

Yes, although I don't see why you asked this question in the zoology section.

Answer 2

Yes

Answer 3

I don't think there's any. They are very good in athletics, in general, but why they are lacking (if any) in science, is largely unknown. Many studies have been done, including that by William Shockley, the co-inventor of transistor, but nothing very conclusive has come out yet.
