Through a careful process of Selective breeding, dog breeders mixed different dogs with different physical traits to create new forms. Darwin was intrigued by what he was seeing breeders could do with domestic dogs. They could select forindividual such as size or shape, and they could change the look of their breed​

How do temperature and salinity affect deepwater currents? question 15 options: as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
