Explain how a population of insects could become resistant to a pesticide?

Ironically, from being exposed to the pesticide for a long period of time. Given a long enough timeframe, a insect species will evolve a natural resistance to a chemical through natural selection.
Insects quickly develop resistance to insecticides due to natural evolution. As their bodies are exposed to the chemicals, small changes are made until it no longer affects them over many generations.
some insects will have an adaptation that helps them survive and that they pass onto their offspring.
the insect population changes to include more and more resistant members
Answer:
This is evelution in action.
If the insects are exposed to a pesticide that only kills some of them, the only future generations come from resistant parents. If the application if pesticide continues, it weeds out non resistant individuals enhancing the resistence of subsequent generations.

What is the best way to explain this change in survivorship of the pests' population?
The insects with pesticide-resistant traits survived and reproduced.
A pesticide kills 99.9 percent of a pest population What will be the result of the continued application of this pesticide?
the 0.1% of the population would be resistant, should they breed the sucessive populations would be resistant resulting in the product becoming ineffective over time Study Island Question : Chemicals can affect an ecosystem. Which of the following is a result of pesticide application? Answer: Pesticide kills all kinds of insects, including predatory insects, which in turn can increase the population of insects for which the pesticide was intended.
How do you explain what is without survivorship?
The insects with pesticide-resistant traits survived and reproduced. do study island u scrub
What is an unintended consequence of using pesticide of plants?
The rise of pesticide-resistant insects.
How does the use of antibiotics and pesticides cause resistance in insects and bacteria?
The use of antibiotics and pesticides creates an artificial selection scenario that culls bacteria and insects that cannot survive the treatments. Those micro-organisms and insects that do not succumb to the effects of antibiotics and pesticides survive to reproduce, and their offspring share their resistance to the antibiotics and pesticides that did not kill them. Now the entire population is resistant. Here is an example of how to make a population of insects pesticide resistant (micro-organisms respond similarly to antibiotics): Assumption: Insect Population I has a 99% mortality when exposed to Pesticide P Stage 1: 100,000 Population I insects are treated with Pesticide P Stage 2: Pesticide P treatment kills 99% of Population P Stage 3: 1,000 insects survive and reproduce Stage 4: Population R is 100% resistant to Pesticide P
Why can insects adapt very quickly to pesticides?
inherited genes that made it resistant to the pesticide
What is a chemical used to lower the population of insects inheritance landfill adaptation or pesticide?
pesticide didn't ya'll learn this at school
Which statement best illustrates a rapid biological adaptation that has actually occurred?
Pesticide-resistant insects have developed in certain environments.
How did pesticide-resistant insects came about as a result of evolution?
Natural selection, the method by which evolution works, is driven by the fact that organisms that die before reproducing do not pass on their genes to their offspring and because of this only those that can survive long enough to reproduce will do so and thus populations tend to be filled with those who survive the best in their current environment. The few bugs that don't die from pesticide reproduce and have (mostly) pesticide-resistant offspring that, in turn, have even more pesticide-resistant offspring.
When a pesticide is sprayed on a population of insects all insects do not get killed but few of them survive give reason?
Poisons are rated by LD50, the dose that kills 50% of a population. The dose can be increased to an LD90, LD99 or whatever but you can never guarantee that the dose will kill them all, as some individuals are more resistant to a specific poison than others are.To get the last few highly resistant individuals may require a dose many orders of magnitude larger than the LD50.
What might be one negative result of growing this specific GMO?
The insects could grow resistant to the pesticide in the genetically-modified corn and become immune to regular pesticides.
What is the difference between pesticide and insecticide?
Insecticides target insects and their larvae whereas pesticides are designed to eliminate the harm done to crops by such pests as mice , birds or fish . See related links below to additional information regarding insecticides and pesticides .
