10. in a series of experiments, griffith infected mice with nonvirulent r-strain bacteria and highly virulent s-strain bacteria. heat-killed s
bacteria were nonvirulent. however, the nonvirulent heat-killed s bacteria and the nonvirulent r bacteria together produced a virulent
mixture. what did this demonstrate?
a. the s-strain bacteria had not been killed completely
b. the molecules present on the outside of bacteria determine whether it's virulent or nonvirulent
c. a transforming principle in the fly bacteria allowed the nonvirulent r strain to become virulent
d. the translation of proteins, carbohydrates, lipids, and dna is important in determining bacterial virulence.

Hurry i need your (100 points) 1) what are the responsibilities of the region of the brain highlighted below?
