Answer: They create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
The temperature and salinity has a major impact on water current of oceanic water. The warm water is usually less denser than colder water, so it remains at the surface of water body, whereas the colder water being more in density remain in a depth. The salinity of cold water is more than the warm water.
According to the above explanation, they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them is the correct explanation.
In the lytic cycle, a virus that has invaded and entered a cell takes over the cell's replication mechanism. The virus makes viral DNA and viral proteins.
The virus then lyses (breaks open) the cell membrane, allowing the newly produced viruses to leave the now disintergrated host cell to infect other new cells.
The lytic cycle is considered the main method of viral replication. It is even more common than the lysogenic cycle. It has helped scientists understand better how the immune system responds to pathogens.
I think the answer would be c. because for birds with longer beaks, it was easier to eat seeds off a cactus (for example), and for birds with shorter seeds, it was easier to eat seeds off the ground.
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
