Disinfectants are a type of antibiotic. Brand X kills 99.9% of all bacteria when used as directed. .1% of the bacteria survive.
Let us say that the treated area is 1 square foot and the original population one type of bacteria was 1 million. This means that 10,000 of these bacteria survived due to any various differences between them and the dead. The 10,000 divide every 24 hours so, in a very short time, the 1 square foot area is repopulated with bacteria that has the genetic potential to survive the next round of disinfectants. Not all of these offspring will. Over time our handy dandy disinfectant only kills 80% and the amount of bacteria is still enough to cause illness.
Extrapolate this scenario to the interior of the human body and the use of medications. Add the fact that many people DO NOT use them as directed any more than most people use a surface disinfectant as directed and we have a neat little breeding ground where natural selection occurs at an alarming rate.

What is an example of direct evidence for evolution is... genetic changes in plants antibiotic resistance in bacteria pesticide resistance in insects or all of the above?
All of the above examples are direct evidence for evolution. Genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects all demonstrate how species can adapt and evolve to survive in changing environments. This supports the theory of evolution by natural selection.
What is an example of micro evolution in organisms?
An example of microevolution in organisms is the development of antibiotic resistance in bacteria. Through repeated exposure to antibiotics, bacteria may develop genetic mutations that confer resistance to the drug, allowing those bacteria to survive and reproduce, leading to the evolution of a population that is no longer susceptible to the antibiotic.
What are some examples of mutations that benefited an organism?
Examples of beneficial mutations include the development of antibiotic resistance in bacteria, the ability of some individuals to digest lactose in adulthood, and the evolution of pesticide resistance in insects. These mutations provided a survival advantage to the organisms carrying them in their respective environments.
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.
Is it malaria related to natural selection?
Yes, natural selection plays a role in the evolution of genetic resistance to malaria. Individuals with genetic traits that provide resistance to the disease are more likely to survive and pass on their genes, leading to a higher prevalence of resistance in populations where malaria is endemic. This evolutionary process is an example of natural selection in action.
What is an example of direct evidence for evolution is... genetic changes in plants antibiotic resistance in bacteria pesticide resistance in insects or all of the above?
All of the above examples are direct evidence for evolution. Genetic changes in plants, antibiotic resistance in bacteria, and pesticide resistance in insects all demonstrate how species can adapt and evolve to survive in changing environments. This supports the theory of evolution by natural selection.
How has crop dusting led to pesticide resistance?
The act of crop dusting itself has not led to pesticide resistance. Mismanagement of pesticide application is the root cause of pesticide resistance.
What is Population Resistance?
Population resistance is also known as pesticide resistance. Pesticide resistance describes a pest population's increasing resistance to a pesticide that use to be effective in terminating said pests.
What is a world example of evolution?
The development of resistance to antibiotics by bacteria is a real world example of evolution.
What is pesticide resistance.?
Pesticide resistance describes the decreased susceptibility of a pest population to a pesticide that was previously effective at controlling the pest.
The resistance of many bacterial species to antibiotics is an example of?
bacterial evolution (microevolution)
What original event resulted in evolution of insecticide resistance in some insects?
The application of dichlorodiphenyltrichloroethane (DDT) is considered the original event that resulted in the evolution of pesticide resistance in some insects. The incident numbers among the pivotal events in the twentieth century since its first applications date to the 1940s. Immunity to the pesticide's toxic effects may be traced back to as early as 1947.
How does pesticide resistance develop over time?
The pesticide resistance develops over time due to the natural selection.
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.
Pesticide resistance in mosquitoes is an example of?
accelerated rates of natural selection due to human involvement.. natural selection caused by human intervention.
What is an example of micro evolution in organisms?
An example of microevolution in organisms is the development of antibiotic resistance in bacteria. Through repeated exposure to antibiotics, bacteria may develop genetic mutations that confer resistance to the drug, allowing those bacteria to survive and reproduce, leading to the evolution of a population that is no longer susceptible to the antibiotic.
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.
