Natural selection is the process by which an organism uses its traits to survive and reproduce. In this mechanism of evolution, organisms have favorable traits for survival and reproduction. The more adapted an organism is to its environment, the more likely it is to have heritable traits that are passed down to new coming offsprings, and really, this also applies for the likeliness of the organism to survive and reproduce in general. The more these heritable traits are passed down and used with offspring, the more common the favorable traits are in the community.
assuming this is plate tectonics: At divergent boundaries where the plates pull apart, magma from the earth's mantle fills in the spaces created.
In the picture attached to this question, the two diagrams above did not show very well but I believe that the first diagram contain four dots, which means that the correct option is A.
Carbon has six electrons, that is why 6 is its atomic number is 6 . In writing electronic configuration, two electrons are usually placed in the most inner shell while the other shells will have 8 electrons each. In the case of carbon which has 6 electrons, only four will remain after 2 electron has been put in its inner shell. Therefore the number of electron in its outermost shell will be four.
