Can cells live and reproduce in the presence of antibiotic?
Cells that are resistant to antibiotics can survive and reproduce in the presence of antibiotics. However, non-resistant cells are typically unable to survive and reproduce in the presence of antibiotics. This is why antibiotic resistance is a growing concern in the medical field.
Explain how the process of natural selection results in populations of bacteria that are not harmed by antibiotics?
The process of natural selection results in populations of bacteria that are not harmed by antibiotics because bacteria that are born with mutations that make them immune to antibiotics will be the ones to survive and reproduce.
What does antibiotic resistance and pesticide resistance have to do with evolution?
When antibiotics and antibiotics are used frequently, the populations evolve a natural immunity to them. this is best explained by Darwin's theory of survival of the fittest, individuals with the best-adapted traits will be the only ones to survive, reproduce, and pass on their traits.
Why can't viruses be treated with antibioticts?
Antibiotics work in ways that would not effect a virus. For example some antibiotics work on the cell wall of the organism. Others block protein synthesis by binding ribosomes. Viruses are merely nucleic acid (RNA and or DNA) and protein. That means antibiotics are ineffective on viruses.
Why are antibiotics not effective against vurses?
Antibiotics are designed to target specific structures or functions in bacteria, such as cell walls or protein synthesis, which viruses do not possess. Viruses operate differently, relying on host cells to reproduce and lacking the cellular machinery that antibiotics disrupt. Consequently, using antibiotics against viral infections is ineffective and can contribute to antibiotic resistance. Instead, antiviral medications are required to treat viral infections.
What viruses cannot?
They can not reproduce without a host as reproductive vector. They have no metabolism and do not preform cellular functions. Viruses are genetic material enclosed in a protein capsid.
How can you use superbugs as an example of natural selection?
Superbugs that develop resistance to antibiotics through genetic mutations provide a clear example of natural selection in action. When exposed to antibiotics, the individuals with mutations that confer resistance are more likely to survive and reproduce, passing on their resistant genes to the next generation. Over time, this can lead to a population of bacteria that is predominantly resistant to antibiotics.
When antibiotics were first developed most infectious diseases could be controlled by them. Today certain bacteria are resistant to many antibiotics. One possible explanation for this change is that?
overuse and misuse of antibiotics have led to the emergence of antibiotic-resistant bacteria. When antibiotics are prescribed unnecessarily or not taken as directed, it creates an environment where only the strongest bacteria survive and reproduce, leading to resistant strains. Additionally, the widespread use of antibiotics in agriculture can contribute to this resistance. As a result, infections that were once easily treatable are becoming increasingly difficult to manage.
Why can't antibiotics kill viruses?
Antibiotics kills single bacteria and stop bacterial growth by binding to the ribosomes of the bacteria but a virus is a different vivacity form. when people clutch antibiotics for a virus it isn't going to kill the virus but can lead to the body to become immune to the antibiotics or help the microbes it was designed to skirmish become resistant to it which is why there are so abundant super bugs out there.no
What are the differences between viruses and bacteria?
Bacteria: Bacteria can be killed by antibiotics. Bacteria is larger. Bacteria can reproduce from the life cycle. Viruses: Viruses cant be killed by antibiotics. Viruses are smaller than bacteria. Viruses cant reproduce without help from a host cell or organism.
How does the development of MSRA illustrate how adaptation and natural selection can lead to the development of new strains of microorganisms?
MRSA developed as its ancestors were stressed and mostly killed by antibiotics. Some few individuals had a resistance to these antibiotics and survived. These resistant individuals then had offspring passing on this resistance. We can see survival of the fittest at work and its results because bacteria reproduce so rapidly.
Why don and rsquot antibiotics work on viruses?
Antibiotics target specific bacterial structures and functions, such as cell walls and protein synthesis, which are absent in viruses. Viruses lack the cellular machinery to replicate independently and instead hijack host cells to reproduce. Consequently, antibiotics are ineffective against viral infections, which require antiviral medications that specifically disrupt viral replication processes. This distinction is crucial for appropriate treatment choices.
