Answer: Natural selection can be defined as the differential survival and reproduction of members of the population of a species that have suitable traits to survive in a population of species.
Explanation:
The punctuated changes in the population of species have been found inordinately faster in the geological time scale, but changes per-generation have been relatively slow. Also, the rate of evolution in such a population is also slow. The punctuated changes in the population are because of evolution but the per-generation changes are the outcomes of the natural selection, in which only the beneficial traits are passed from one generation to another.
Answer:
a gradual increase in the overall temperature of the earth's atmosphere because of the greenhouse effect caused by increased levels of pollutants.
Explanation:
The atomic number of an element is the same as the number of protons in the nucleus of an atom
Answer:
Metamorphic rock
Explanation:
metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under this condition because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals.
