Question

A researcher was studying mutations in bacteria. He found that certain bacteria had changes in their DNA that allowed them to be resistant to antibiotics. This research is an example of 1._______The mutation will lead to 2.________.
1.
A.Embryology
B. Evolution Genetics
C.Comparative Anatomy

2.
A. All the bacteria becoming resistant to the specific Antibiotics
B. The Bacteria becoming nonresistant to specific Antibiotics
C. Less Bacteria becoming resistant to the specific Antibiotics

Answer 1

Answer:

1. B

2.C

Explanation:

Answer 2

Answer is option "1 B & 2 C"

Explanation:

• Evolution genetics is a field of science, which includes the study of genetic variations that lead to evolutionary changes in organisms
• As some bacteria had changed their DNA that led to the 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  
• Hence, the right answer is option 1 B and 2 C " evolution Genetics & less bacteria becoming resistant to the specific antibiotics"
