Volcanoes form at different plate boundaries because of the plates divergent and convergent nature. the plates are always in motion, however minimal they may be. When the plates move apart from each other, the magma from below comes up to fill in the vacant space and thus a volcano is formed. It may be the other way round also and that is the magma forces the plates to move away and this results in the formation of a volcano. When one of plates dives under another plate, then the pressure creates melting of the mantle and thereby forms magma which in turn creates volcanoes.
Answer:
It is found only in animal cells.
<span>The answer is </span>‘<span>the molecule would have to be longer to be more
sensitive to red light and shorter to be more sensitive to blue light.</span>’The cones change shape and vary their length once
they absorb a photon. This change is transduced, through biochemical pathways, into nerve impulse and carried
to the brain.
Recombination occurs when two molecus of dna exchange pieces of their genetic material with each other .
Step by step
Mutations result from an error in DNA replication, should it be from an alien source (like radiation) or simply a mistake in replication. Migration of organisms to a new population would alter the DNA by adding new genes, but it would not mutate them.
