At first, the new insecticide is effective against the boll weevil. Spraying the insecticide will kill the boll weevil in a way. The insecticide might attack boll weevil enzyme or any part of its organs.<span>
But some of them might have a mutation that renders the insecticide ineffective. The mutation probably happens to DNA that code the enzyme or protein that targeted by the insecticide, makes the insecticide completely ineffective.
The next spray will kill all old organism, leaving the new resistant organism in less competition area. This will allow the resistant organism to grow fast and eventually replace all the old organism in the area.</span>

Chlorophyll pigments (mainly chlorophyll a and b) absorb the red and blue spectrum of visible light in the electromagnetic spectrum for photosynthesis. This is why leaves appear green (and occasionally orange) because this visible light portion is not absorbed. The blue light absorbed by leaves ranges between 400 – 450 nm while the red light ranges between 500 nm and 700 nm.
