A independent variable is a variable which the experimenter can control and by changing the independent variable the experimenter observes or records the value of dependent variable.
so i see if you are asking independent than the answer is A.
if you are asking dependent variable than the answer may be B because manipulated by changes to the independent variable would be the best answer.
Answer:
The correct answer is "I, II, and III".
Explanation:
The missing options of this question are:
I only
II only
III only
I, II, and III
The correct answer is "I, II, and III".
Antibiotics are of different spectrums of activity depending on the number of pathogens they can kill. They are different reasons for this differences in antibiotic specificity:
I. Antibiotics interrupt processes found in some but not all pathogen cells. For instance, some antibiotics are directed to cell walls that not all bacteria posses.
II. Some pathogens have no metabolic processes to interrupt. The antibiotics that are directed to metabolic reactions of bacteria are not effective in treating viruses because they do not perform this metabolic reactions.
III. Some pathogens have developed genetic resistance to specific antibiotics. Bacteria have a remarkable genetic plasticity having plasmids that can be easily transmitted among them, which give them antibiotic resistance.

Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds. Covalent compounds have bonds where electrons are shared between atoms.
