According to the theory proposed by Harry Hess, what causes continents to move?
The correct answer is : seafloor spreading.
Earlier, in 1912 Alfred Wegener produced evidence that the continents are in motion but this idea was shelved as he could not explain what forces the continents to move. So, almost 50 years later Harry Hess confirmed Wegener's ideas by using the evidence of seafloor spreading to explain what moved continents.
The answer is C. A mycorrhiza is a symbiotic association
between a fungus and the roots of a vascular host plant. They colonize the roots
of vascular plants connect them, one to the other; and then send out their
filaments, called hyphae, as much as 200 times farther into the soil than the
roots they colonize.

Most people afflicted with recessive disorder with recessive disorders are born to parents who are not affected at all by the disease. Most genetic disorders of humans are caused by recessive alleles. Dominant alleles on the hand cause lethal disorders, however they are less common compared to the recessive alleles disorders, this is because most individuals carrying a lethal dominant allele have the disorder and they die before pass it to the offspring, while the individuals with the recessive lethal genes are more likely to be healthy and reproduce.
