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.
Bacterial resistance can be resolved by not over using antibiotics. It can also be done by not taking a really high dose of antibiotics. Many times antibiotics are over prescribed.

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?

Which biological agent may be susceptibal to anitbiotics but may develop resistance?
bacteria
What is bacteria resistance?
Bacteria resistance refers to the ability of bacteria to withstand the effects of antibiotics or other antimicrobial drugs, reducing or eliminating their effectiveness in killing the bacteria. This resistance can develop through genetic mutations or acquisition of resistance genes from other bacteria, leading to treatment challenges and increased risk of uncontrolled infections.
What happens to bacteria over time when exposed to antibiotics frequently?
Bacteria can develop resistance to antibiotics through genetic mutations or by acquiring resistance genes from other bacteria. Over time, the resistant bacteria population can grow, making the antibiotics less effective in treating infections caused by those bacteria. This can lead to treatment failure and the need for more powerful antibiotics.
Which biological agent may be susceptible to antibiotic's but can develope resistance?
Bacteria are biological agents that are susceptible to antibiotics but can develop resistance through genetic mutations or acquiring resistance genes from other bacteria. Overuse or misuse of antibiotics can accelerate this process, leading to the development of drug-resistant bacterial strains.
What type of scientist studies how bacteria are affected by antibiotics?
A microbiologist or medical scientist would study how bacteria are affected by antibiotics. They can investigate how bacteria develop resistance to antibiotics and explore new ways to combat antibiotic resistance.
What are two examples of biological resistance?
Antibiotic resistance: Bacteria can develop resistance to antibiotics through genetic mutations, making the drugs less effective in treating infections. Pesticide resistance: Insects can develop resistance to pesticides over time, reducing the effectiveness of pest management strategies in agriculture.
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.
