The direction iron in ocean rocks points
The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.
Explanation:
These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.
The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.

Enzymes bind with chemical reactants called substrates
Answer:Exercise increases the rate at which energy is needed from food, increasing the need for both food and oxygen by the body. This is why when we exercise both pulse/heart rate and breathing rate increase.

Answer:
(B)iology
Explanation:
Biology is a branch of science that studies about the living organisms.
Answer:
A. It contributes to global warming
Explanation:
- Solar power is the power of the future and is an essential nonrenewable source of energy for man. Solar power is driven by the incoming solar energy in the form of solar rays.
- Solar power is eco-friendly and doe not cause any harm can be sued in the summer season and has ample scope for greenhouse gases.
- As per the statement, the solar power should be used as the main energy source in U.S can be contradicted by saying it contributes to global warming.
