For a gene when its in hard weinberg equilibrium it is not evolving
Well you didn’t really give us the list of words so I’m not able to answer this
Jmale chromosome because it contains X and Y whereas women contains only X and X
The answer I got is A) Orchids
Answer:
Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
Explanation:
Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.
