The mutations are random and confer on some members of the bacterial population resistance to certain drugs and these members are the ones selected to survive and reproduce the next population of bacteria with the resistance to these certain drugs.

Is penicillin a bacteria?
Yes, penicillin prevents the formation of new bacterial cell wall. If a bacteria reproduces, new cell wall cannot be produced and the cell lyses and dies. However penicillin has no effect on a quiescent (non-reproducing) bacteria. Therefore penicillin is also called a bacteriostatic agent (prevents growth of bacteria), which means penicillin does stop bacteria from reproducing.
What is the biggest challenge in the field of microbiology?
Developing new antibiotics that are effective against multi-drug resistant strains of pathogenic bacteria such as methicillin resistant Staph.
What kind of drug kills bacteria?
The types of drugs that can kill bacteria are called 'antibiotics'.
What is a substance that can be obtained from bacteria or fungi and can be used as a drug to fight pathogenic bacteria?
The answer to this question would be: Antibiotic
A situation in which bacteria receive sugar from plants and the plants receive nitrogen from the bacteria is known as?
A drug deal.
What is bacteria resistance?
It is when a certain bacteria resists a drug such as antibiotics
What is antibitic?
The term antibiotic means against life. Anti = against and bio= life. So this is a product or a drug that will destroy bacteria( life).
What causes the mutant form of disease-causing bacteria to become predominant?
The forces that affect bacteria population are competition, mutation and selection, just like any other population affected by the theory of evolution. In a large population of bacteria, some individuals will be mutated to have resistance to antibiotic drugs (or any other drug). This is a disadvantage to the individual as long as there is no antibiotic drug in the surroundings. In this case there is mutation but no selection. When an antibiotic drug is given to a patient, selection is being done in the evolutionary aspect of the bacteria. Only the drug-resistant mutants survive, since the selection does not affect them. All the non-mutant bacteria die; the mutants have no competition, and can flourish undisturbed.
How is the presence of antibiotic resistance used as a marker in bacterial transformation?
Antibiotics will kill off all of the bacteria that have not mutated and formed a resistance to the drug. Those that have a resistance to the antibiotics will survive and multiply into many resistant bacterium. This continuously facilitates the production of new kinds of antibiotic resistant bacteria
A drug that inhibits mitosis such as griseofulvin would be more effective against a. Fungi. b. Gram-positive bacteria c. Mycobacteria d. Wall-less bacteria e. Gram-negative bacteria?
a. fungi
What medications interact with amoxicillin and flagyl?
Together they act better. Amoxicillin is one of the best antibiotic for aerobic bacteria. Another drug is metronidazole. It act against most of the anaerobic bacteria.
The drug used against intestinal anaerobic bacteria that can also alter normal flora causing antibiotic-associated colitis is?
Clindamycin

Can fluidity influence by certain drug?
Yes, the fluidity of a certain drug can affect the effectiveness of that particular drug.

Drug resistant micro-organisms produce lysozyme?
Lysozyme is an enzyme occurring naturally in egg white, human tears, saliva, and other body fluids, capable of destroying the cell walls of certain bacteria and thereby acting as a mild antiseptic. Gram-negative bacteria are drug resistant micro-organisms that produce lysozyme.
