Answer:
The seafloor is only 180 million years old due to the process of subduction. The floor of the sea's tends to get colder and denser with the passage of time. At a certain time, the seafloor becomes so dense that it sinks in the upper mantle. The Earth's crust cannot undergo this process and hence has oldest rocks. We can say that the seafloor is less than 180 million years old because it is typically recycled back into the mantle of the Earth.

Explanation:
<u>Answer</u>:
Cancer cells can reproduce rapidly because they spend less time in interphase.
<u>Explanation</u>:

Cancer cells avoids the signals and keep on destroying the body cells. They never undergo apoptosis when should go, so they are referred as the immortals. These cells use body’s protein and fat as fuel to undergo their processes in the absence of sugar. Excess sugar also acts as fuel for the growth of the cancer cells.
Answer:longitudinal design
Explanation: we need to know what is longitudinal design. By definition,
longitudinal design is the study of variables or group of variables which have similar cases and repeated over a long on short period of time. This cases happened between a similar group( teenage girls ), and it happened repeatedly over a long period of time, so this will require a longitudinal design.
