<span>Since a gene that acts as a pesticide is inserted into a corn, that corn is now safe from insects. This will happen because the corn will probably synthesise protein according to that inserted DNA sequence and that protein will serve as a repellent to the insects. However, the Red Queen's hypothesis in evolution explains that organisms must constantly adapt and evolve in order to survive. This refers to insects. If they could not eat genetically modified corn, they would extinct. So, they must adapt or evolve in order to survive. So, it is expected that insects that are resistant to this specific pesticide would develop through the time.</span>

Identify advantages and disadvantages of using fossil fuels, hydroelectricity, and solar energy as energy sources.
dimaraw [331]
Fossil fuels:

Advantage: easier to find and transport
They generate thousands of jobs

Disadvantage: butning fossil fuels for the environment degrades it and contributes to global warming

Hydroelectric:

Advantage: Hydroelectric power can be created 24/7 indefinitely assuming that the body of water it is utilizing never runs dry. It is also another absolutely clean source of energy.

Disadvantage: The turbines and dams that are built on the rivers or streams interrupt the natural flow of the fish and other wildlife that lives in the area.

Solar energy:

Advantage: Solar power helps to slow/stop global warming. Global warming threatens the survival of human society, as well as the survival of countless species.

Disadvantage: the sun doesn't shine 24 hours a day ao it can supply you with energy at night
