Answer:
sympatric speciation
Explanation:
Species of fruit fly larvae in the genus Rhagoletis each feed on a particular kind of fruit. Rhagoletis pomonella feeds on the small red fruit of the hawthorn tree. In 1865, farmers in the Hudson River valley found that R. pomonella flies had begun attacking their apples and then spread to apple orchards in adjacent areas of Massachusetts and Connecticut. These now separate varieties of flies, the apple and haw flies, usually don't interbreed with each other because their periods of mating coincide with the different ripening times of apples and hawthorn fruit. Each variety is becoming specialized to feed and reproduce in its own particular microhabitat and may be transitioning to separate species.If the apple and haw flies become distinct enough to be separate species, their evolution is an example of sympatric speciation

The correct answer would most likely be A
Answer:
Dehydration Synthesis
The monomers combine with each other via covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
Answer:
A.) An air mass cannot transfer energy from one area to another
Explanation:
The air masses are constantly on the move. They can be warm and moist, or cold and dry, as well as hot and dry, all depending on the place above which they have formed. The air masses that form over warm, large bodies of water and warm and moist. The air masses that form over cold regions are cold and dry, and the air masses that form deeper into the continent in hot regions, are hot and dry. Because the air masses are constantly on the move, they manage to transfer their energy from one area to another, resulting in change of weather conditions as the energy is transferred.
