How does an insect species become resistant to an insecticide?
the more exposure an insect has to the insecticide the weaker the effects of it are.
after an exposure if the insect survives, it mutates to become resistant if it encounters it again.
there are some offspring already resistant to the insecticide's effects that survive and reproduce.
after exposure, all the reproductive cells have mutated to become resistant for the next generation.

In which specialized organ of the plant would these cells most likely be found

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.

Witch type of microscope is used to view very small cell components like proteins and dna?
