Which of the following statements best describe how biological science has developed over time? a. until 50 years ago, only white males made contributions to scientific knowledge b. men and women all over the world have investigated scientific questions throughout history. c. all useful scientific knowledge has developed within the past 100 years. d. no new discoveries are left to be made.

A is wrong, because that fact just simply is not true. There have been several other raced men and some women as well that made important contributions to science.

B is correct, because science isn't attributable to just the last couple of hundred years. In ancient times, people developed astronomy and medicine. This is also correct because it names females as part of the scientific contributions to society.

C is incorrect, because this fact is also completely false. Lots of important scientific discoveries have been made from before that, such as the invention of electricity (somewhat useful today I would guess :\ ) in 1879, which is much longer than 100 years ago.

D is also incorrect, because scientific knowledge is changing constantly, every minute, growing and expanding and changing to accomodate new knowledge and information that we've discovered.

i have to report this, it doesn't relate to biology
