Bacteria, like all organisms, have phenotypic variations. Some bacteria are resistant to antibacterial drugs and survive the onslaught of these drugs. They then go on to have progeny ( by fission ) that they confer this resistance on so that you have a new population of resistant bacteria.

What effect might antibacterial soaps have on the evolution of bacteria?
Provide a selective environment where those with resistance survive and replicate and those without die off. Gives rise to resistant bacteria.
What do bacteria develop through natural selection?
A random mutation is introduced into the genome, whether by genetic mistake or otherwise. If it makes any difference to the behavior of the bacterium is unlikely, but if it is beneficial it will have an advantage over competitors. Which makes it more likely for it to reproduce and more likely to pass on the beneficial mutation. This process repeats and success! The bacterium has evolved.
Natural selection example?
A great example would be Antibiotics and Bacteria. When humans create an antibiotic, it wipes out a lot of the bacteria in your body. The ones that that don't get affected by it probably have a resistance to the antibiotic. As those bacteria multiply and grow, the others die out due to the antibioitic. Soon the anti-biotic resistant bacteria will take over the human body, and the humans would have to find another antibiotic to counter the new bacteria. The cycle goes on and on......
Why does food stay fresh longer when kept in the refrigerator?
The bacteria that makes food go 'bad' needs warm places to reproduce. Keeping food in the fridge slows down the bacteria. In many cases chilled foods start to develop bacteria that cause foods contaminate at or above 8 degrees. Domestic and industrial refrigeration runs at 2 to 6 degrees
Which has a higher resistance insulators or conductors?
No, the resistance of an insulator is very high.
Which Biological agent susceptible to antibiotics but can develop resistance to them?
B- Bacteria
What biological agent may be suspectible to but can develop resistance?
Bacteria
What biological agent may be susceptible to antibiotics and can develop resistance?
Bacteria
Which biological agents may be susceptible to anitbiotics but can develop resistance?
Bacteria
Which biological agent may susceptible to antibiotics but can develop resistance?
bacteria
Which biological agent may be susceptibal to anitbiotics but may develop resistance?
bacteria
What happens to bacteria over time when exposed to antibiotics frequently?
They develop resistance to antibiotics .
How can bacterial populations develop drug resistance and share that resistance with other bacteria?
resistance mechanisms often carried by plasmids can be easily transmitted in bacterial populations by conjugation
Why does drug resistance develop so rapidly in a population of bacteria?
Drug resistance develops so rapidly because bacteria reproduce extremely quickly, giving a better chance for ones with resistance to develop and spread.
Antibiotic in gene cloning?
If antibiotic resistance is added to the gene being cloned, antibiotics can be used to isolate the transformed bacteria (ones with the gene being cloned) by killing off all non-transformed bacteria, that don't have the antibiotic resistance. There is a chance that the non-transformed bacteria can mutate to develop antibiotic resistance.
What biological agent may be susceptible to anti?
What biological agaent may be susceptible to anyti-biotics, but can develop resistance? bacteria
How is resistance to antibiotics shared from one bacteria to another?
Bacteria develop resistance to antibiotics through the process of natural selection. The antibiotic will kill most of the population of bacteria but not all because some of them already have the resistance. Also if the antibiotic is not utilized correctly ( according to a physicians instructions ) some of the more hardy individuals of the bacteria population will live. These bacteria breed and produce offspring that are also more resistant to antibiotics. Generations of bacteria happen much more rapidly than with people so the ability of bacteria to adapt to new environments is much more robust with respect to time.
