assuming this is plate tectonics: At divergent boundaries where the plates pull apart, magma from the earth's mantle fills in the spaces created.
Answer:
Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.
two Barr bodies
A Barr body is the inactivated X chromosome when in a case like this, there is more than one X chromosome for only one place. In this case, because there are two more X chromosomes than it would be normal, it will result in two Barr bodies. So, the number of Barr bodies will be <span>is always the total number of X chromosomes minus one.</span>
Fungi and bacteria
They break down the dead organisms and create new healthy soil
