What is an explanation of how antibiotic resistance occurs?
Bacterial resistances are developed due to mutations that are passed down from generations of bacteria. Antibiotics generally kill all but the strongest bacteria or bacteria that have resistances to these antibiotics, resulting in only these bacteria reproducing, passing on the antibiotic resistances to future generations. Over time, entire populations of bacteria can develop a resistance to an antibiotic if they are frequently exposed to it.

Clinical implication of resistant?
The antibiotic tested is not likely to be effective in eradicating the infection. *The infectious agents are a strain that have developed (evolved) a natural resistance to a particular antibiotic.
What is a beneficial feature that evolved by means of natural selection?
Camouflage is a beneficial feature that evolved through natural selection, as it allows organisms to blend in with their environment and escape predators. This adaptation increases an individual's chances of survival and reproductive success, ultimately leading to its increased prevalence in the population over time.
What animal evolved by natural selection?
All animals, including Homo sapiens, did and do.
How animal will prevent mutation?
Animals cannot prevent mutations from occurring, as mutations are random changes in the DNA sequence that happen naturally during cell division. However, organisms have evolved systems like DNA repair mechanisms and checkpoints during cell division to minimize the impact of mutations. Additionally, natural selection acts to remove harmful mutations from a population over time.
What processes occurred before human evolved?
The same evolutionary processes, natural selection, genetic drift, gene flow and simple mutation, occurred before humans evolved and are still occurring today.
How did human beings come to existence according to Darwin?
According to Darwin's theory of evolution by natural selection, human beings evolved through a process of genetic mutation and adaptation over millions of years. Through this process, early hominids gradually evolved and developed traits that resulted in the modern human species.
What is an example of micro-evolution?
An example of micro-evolution is the development of antibiotic resistance in bacteria due to natural selection. When exposed to antibiotics, bacteria with genetic mutations that provide resistance to the drug survive and reproduce, passing on the resistant trait to future generations. Over time, the proportion of resistant bacteria in the population increases, leading to the evolution of antibiotic-resistant strains.
How have bacteria evolved resistance to penicillin?
natural selection, if a victim of a bacterial disease takes penicillin and the bacteria survives it is spread and reproduces, but those that don't have more resistance are either destroyed or have lower numbers
How has animation evolved?
Natural selection.
What does materialistic evolution mean?
Materialistic evolution is the idea that all living organisms have evolved through natural selection and genetic mutation, without the need for any supernatural or divine intervention. It focuses on the purely physical processes that drive evolution, such as genetic variation and environmental pressures.
What is antibiotic resistant bacteria?
Also known as "superbugs", antibiotic resistant bacteria have evolved to a point that our usual antibiotics won't kill them. VRE and MRSA are common forms of antibiotic resistant bacteria.

How through natural gene mutation animals have evolved?
baxter made all the animals

Which of the following organisms likely evolved by natural selection?
Dolphins.
What is artificial evolution?
Artificial evolution is a computational technique inspired by biological evolution, where populations of candidate solutions to a problem are evolved through mutation, selection, and recombination. It can be used to optimize complex systems, find optimal solutions, or train machine learning models.
