Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of Select Answer , where the magma is much hotter than the surrounding magma. These are Select Answer and do not move with tectonic plates. They are responsible for the creation of Select Answer island chains.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
