Answers
Answer:
Atomic Number: 8
Number of neutrons: 8
Mass of neutrons: 16 (AMU if you want the units)
Explanation:
The answer for both the number of neutrons and atomic number is on the top
The mass is at the bottom
Answer:
An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how many protons are in the atom's nucleus.

Which of the following mechanisms of change in genefrequencies is responsible for the antibiotic resistance of E. coli in this experiment?
A. founder effect
B. natural selection
C. population bottleneck
D. genetic drift
Answers
Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.
Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.
In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.
Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.
The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.
E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.
In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.
Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.
Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.
