Bacteria can evolve quickly because they reproduce at a fast rate. Mutations in the DNA of bacteria can produce new characteristics. A random mutation might cause some bacteria to become resistant to certain antibiotics, such as penicillin.
Full Answer
Oct 29, 2016 · Why is the evolution of antibiotic resistance in bacteria happening so quickly? a. because of overuse of antibiotics in humans b. because bacteria can reproduce so quickly c. because any use of antibiotics will select for resistant bacteria d. because of overuse of antibiotics in livestock e. All of the above are correct.

Antibiotic resistance is accelerated when the presence of antibiotics pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection. The antibiotic-resistant germs survive and multiply.
The development of generations of antibiotic-resistant microbes and their distribution in microbial populations throughout the biosphere are the results of many years of unremitting selection pressure from human applications of antibiotics, via underuse, overuse, and misuse.
Bacteria can evolve quickly because they reproduce at a fast rate. Mutations of bacteria produce new strains. Some bacteria might become resistant to certain antibiotics , such as penicillin, and cannot be destroyed by the antibiotic. The evolution of the bacteria is an example of natural selection .
"The experiment shows just how easy it is for bacteria to evolve resistance – how quickly evolution can occur. In just 11 days, resistance levels increased by over 1000-fold," said Professor Kishony.Oct 4, 2016
A random mutation occurs in the DNA of individual bacterial cells. The mutation protects the bacterial cell from the effects of the antibiotic - it becomes antibiotic resistant. Bacteria without the mutation die when the antibiotic is present.
Bacteria evolve quickly because they grow fast and can share genes. Helpful mutations spread quickly in bacteria.Dec 15, 2006
Numerically and by biomass, bacteria are the most successful organisms on Earth. Much of this success is due to their small size and relative simplicity, which allows for fast reproduction and correspondingly rapid evolution.May 25, 2011
This adaptation is under tight genetic control, involving the expression of multiple genes. Bacteria react to a sudden change in their environment by expressing or repressing the expression of a whole lost of genes. This response changes the properties of both the interior of the organism and its surface chemistry.
The main steps in the development of antibiotic resistance in bacteria are: A random mutation occurs in the DNA of individual bacterial cells. The mutation protects the bacterial cell from the effects of the antibiotic - it becomes antibiotic resistant.
Over time the whole population of bacteria becomes antibiotic resistant because the antibiotic resistant bacteria are best suited to their environment.
In order to reduce the rate of development of antibiotic resistant strains: 1 doctors should not prescribe antibiotics inappropriately, such as for the treatment of non-serious infections 2 patients should always complete the full course of antibiotics to ensure all bacteria are killed and none survive to mutate and form resistant strains 3 the agricultural use of antibiotics should be restricted
Bacteria can evolve quickly because they reproduce at a fast rate. Mutations in the DNA of bacteria can produce new characteristics. A random mutation might cause some bacteria to become resistant to certain antibiotics, such as penicillin. Antibiotics usually kill bacteria, but in this case the mutation means the bacteria cannot be destroyed by the antibiotic. This evolution of antibiotic resistance in bacteria is an example of natural selection leading to evolution.
the agricultural use of antibiotics should be restricted. Penicillin was the first antibiotic to be produced on a mass scale in the 1940s. It is derived from Penicillium fungi, shown here growing on an agar plate.
Antibiotics usually kill bacteria, but in this case the mutation means the bacteria cannot be destroyed by the antibiotic. This evolution of antibiotic resistance in bacteria is an example of natural selection leading to evolution.
