A reseacher was studying mutations in bacteria. he found that certain bacteria had changes in their dna that allowed them to be resistant to antibotics. this research is an example of. The mutation will lead to

1.B). Evolution genetics.

2.C). Less Bacteria becoming resistant to the specific Antibiotics .

Explanation:

Evolution genetics is field of science, which includes study of genetic variations that lead to evolutionary changes in organisms. As some bacteria had changed their DNA that led to development of antibiotic resistance in them.

Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them

Thus, the correct options to be filled in the blanks are option (B) and option (C).

it is very expensive

explanation:

the supermassive black hole is in the middle of the galaxy.
