What is natural selection?
a process that selects variations that with survival and that spreads the variations to more offspring
a process through which nature selects an individual within a population for extinction
a process that causes all populations to gradually increase in size
a process that causes random variations to appear in the offspring of every generation

The correct answer is a process that selects variations that help with survival and that spreads the variations to more offspring.

Explanation:

Natural selection is a phenomenon proposed by Charles Darwin 140 years ago. From its definition the theory of evolution is born.

This process occurs between entities with variation, inheritance and multiplication and the different evolutionary formations that give way to new species through survival and reproduction.

In summary, natural selection is the process of formation of living beings so that they can survive and develop.

primary succession occurs in essentially lifeless areas regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. secondary succession occurs

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
