A cotton farmer applies a new insecticide against the boll weevil to his crop for several years. at first, the treatment was suc
romanna [79]
Yes, it is possible that evolution occurs in this case.

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>

In the area with the largest sea lamprey population, what is being done to reduce this population?
victus00 [196]
In the area with the largest sea lamprey population, a few things are done to reduce and control this population. Lampricide, Currently, the primary method to control sea lampreys utilizes a lampricide, called TFM, that kills sea lamprey larvae in streams with little or no impact on other fish.   Barriers,Barriers have been constructed to block the upstream migration of spawning sea lampreys; most barriers allow other fish to pass with minimal disruption. Barriers have eliminated lampricide treatment on some streams and reduced the stream distance requiring treatment on others. The Sterile-Male-Release-Technique, The sterile-male-release-technique aims to reduce the success of sea lamprey spawning. Each year male sea lampreys are collected and sterilized. When they are released back into streams the sterile males compete with normal males for spawning females. Lastly trapping, Sea lamprey traps are operated at various locations throughout the Great Lakes, often in association with barriers. Traps are designed to catch lampreys as they travel upstream to spawn.
