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>
Answer:
The heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
Explanation:
When Eric-palces some room temperature strawberries into the freezer, he is changing the temeprature of the strawberries. When the strawberries are in the room tempertaure, they are absorbing certain amount of heat.
When they are placed in the freezer they are releasing the heat to the environment and this leads to condition called as phase change. Due to this phenomenon, the heat from the strawberries transfers to the freezer and causes the strawberries to freeze.
