there is genetic variation within the house fly population. The resistant house flies were able to survive the insecticide because they carried genes that made them immune to its effects. Over time, if these resistant house flies survive and reproduce, the overall population may become more resistant to the insecticide.
What else can I help you with?
Within a decade of the introduction of a new insecticide nearly all of the descendants of the target pests were immune to the usual-sized dose the most likely explanation for this immunity is that?
Natural selection is one way to explain it. When the survivals of the insecticide reproduced, the gene that allowed them to live was passed on. In time, the gene was spread throughout the entire population and every member of the pest became immune.
Who developed pure culture technique?
The pure culture technique was developed by German microbiologist Robert Koch in the 1880s. This method involves isolating a single type of microorganism from a mixed population, allowing for its study and identification.
What accounts for the lighter appearance of the pro-amnoin?
The lighter appearance of the pro-amnion is due to its different composition compared to the amnion. The pro-amnion consists of a loose network of cells and fibrous material, which allows it to appear less dense and lighter in color. Additionally, the pro-amnion is more vascularized than the amnion, contributing to its lighter appearance.
Did Thomas Malthus propose a theory of evolution?
Thomas Malthus' work originated around population statistics and how they are affected by different factors. His work was instrumental for Darwin and Wallace's proposal of natural selection. Just to add, no he did not propose a theory of evolution.
What is an example of a living organism that has recently changed due to natural selection?
The high death rate of people who play golf in a thunder storm. And of skateboarders on steep roads.add And the evolution of insecticide resistance by insects, and herbicide resistance by plants. Even if the challenge were removed, if the newly developed variant were in the majority, the old variant may well still fail to prosper.
Why would insect population rebound after the use of DDT?
the insects might have developed a resistance to the insecticide
Who is Teunis Ven-der Linden?
Dutch chemist, developed insecticide "Lindane"

How does systemic kill aphids and cicadas?
Attack against internal organs and disruption of life-sustaining processes are the ways that systemic kills aphids and cicadas. A systemic insecticide has the same effect regardless of the target pest. No insect survives systemic insecticide treatment schedules unless the arthropod in question has developed insecticide resistance or pesticide immunity to laboratory-made and nature-derived products that kill.
A rate which a population is changing?

How is population distribution today from the days before modern science was developed?
How is population distribution today different from the days before modern science was developed
Where would the would the bulk of the population of India be in a less developed country?
India is a country less developed than the others. This is a reason for the hike in population.
What was the first man-made insecticide?
The first man-made insecticide was DDT, which was developed in 1939 by a Swiss chemist named Paul Hermann Müller. DDT was widely used to control insect pests during World War II and in agriculture until its harmful effects on the environment and human health were discovered.
