The amount of fuel that is consumed in transporting these products has led to an increase in the pollution levels in the environment. It has also led to several other environmental concerns such as noise pollution and landscape intrusion.
Answer:
d
Explanation:
D. It continuously controls self-generation and self-maintenance.
genome has instructions for self-generation and self-maintenance.
A. Earth's magnetic field reverses over time; the changes show that seafloor spreading has taken place over time.
Explanation:
The pattern of the magnetic minerals in seafloor ridges are aligned in a repeating pattern because the earth's magnetic field reverses overtime.
This provides evidence because the changes shows that the sea floor spreading has taken place over time.
- The concept of sea floor spreading was first suggested by Harry Hess in the early 1960's.
- Using sophisticated tools, he was able to discover stripe patterns of magnetic minerals in rocks.
- The earth can be likened to a giant bar magnet
- The geomagnetic field originates from the core where the movement of molten metals induces magnetism.
- In a fresh cooling magma, the metallic minerals are able to align their domains with the prevailing magnetic field.
- At some point the magnetic field is normal with a very strong intensity. At other times the intensity is low and it reverses.
- The minerals keeps track of the changes.
- This leads to striped pattern that has been used to suggest sea floor spreading.

Or they could have evolved to adapt to their environment. Because of these mutations, they’re more beneficial to their species and can survive.
