Which of these statements applies to the heritability of phenotypic variation? a) behaviour is based primarily on interaction with the environment and does not respond well to selective pressures. b) only genetically based variation is subject to evolutionary change. c) only traits that vary quantitatively will respond to artificial selection. d) all genotypic and phenotypic variations are heritable

The circles, or orbits, for electrons are called energy levels. each level can hold only a certain number of electrons. add electrons to each level until you can't add any more. how many electrons can each level hold?

What changes the stability of the element

How do temperature and salinity affect deepwater currents? 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. 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 density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
