The only cells that don't have jobs are either stem cells, which are to be used later, or cancer cells, which are extras.
Seafloor spreading occurs when two plates diverge
Explanation:
Fossils are the remains of long-dead organisms, preserved in rock. Because rocks are laid down in layers, one on top of the other, the fossil record is generally set out in date order: the oldest fossils are at the bottom. Running through the fossil record makes it clear that life has changed over time.
BRAINLIST PLEASE!
The answer to your question is C- colder , saltier , and denser why because they don't have the same density level and deep ocean water is more dense than surface. and also From
your feet to your knees the water feels icy cold and from your knees to your head the water feels
warm. You probably wondered what causes this to happen. What you felt were warm surface
currents and cold deep currents. Changes in the density set these currents in motion. some ocean currents are set in motion by the wind other ocean currents are created by something you can't feel or see. Differences in density of water can also cause currents to form and move. Density is affected by temperature and salinity. i hoped i helped
