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.

This explanation and his theory were not widely accepted. Prior to Wegener, however, many had noted that the shapes of the continents seem to fit together, suggesting some schism in the past.
<span>Continental drift was really not allowable as even an accepted theory until the 1950s. Most geologists accepted the theory as quite possible before 1970. Several factors point to the acceptance of the continental drift theory. </span>
<span>Fossil records from separate continents, particularly on the outskirts of continents show the same species. As well mineral specimens along the supposed break lines of the continents are nearly identical. Some identical species exist on certain continents, like an earthworm common to both Africa and South America suggesting the species could not have spontaneously arisen on both continents without some variations hope this helps</span>
The statements that are true of receptor-mediated endocytosis is that It allows the internalization of extracellular substances in clathrin-coated vesicles.
<h3>What is
receptor-mediated endocytosis?</h3>
Receptor-mediated endocytosis can as well be regarded as the clathrin-mediated endocytosis, which can be explained as the process by which cells absorb metabolites as well as hormones, proteins.
It should be noted that in some cases of viruses through the inward budding of the plasma membrane, however the process of endocytosis” can be seen as one that entails both the ingestion of large particles whic could be bacteria as well as the uptake of fluids or macromolecules in small vesicles.
In conclusion, when it take in large moplecules it is known as phagocytosis (cell eating) , in receptor-mediated endocytosis , there is a room for the internalization of extracellular substances in clathrin-coated vesicles.
Therefore, the first option is correct.
