The answers that apply are;
- striped pattern
- provide evidence to seafloor spreading
Ocean ridges can be found at divergent boundaries where two plates are moving away from each other. As the magma rises to fill the void, it cools into rock and forms new crust. The iron minerals in the rocks align with the earth’s magnetic field before the rock cools. This causes the rocks in these areas of seafloor spreading to have band-like patterns. The irons align differently each number of years in relation to the flipping of the earth’s magnetic field. This phenomenon has been used to determine the ages of these rock layers.
Possibly because they were frighted hope i helped (:
The main difference in the process of waste removal between unicellular and multicellular organisms is the fact that unicellular organisms rely on only their membrane and organelles, the whole process is in inside the cytoplasm of the cell and once waste is formed, it is "packed" in special sacs called vacuoles and then, through the process of exocytosis they are being left out of the cell. On the other hand, multicellular organisms most often have specific organs that are in charge of the process of digestion, absorption and excretion or removal of waste.
