I'd try one of these:
*natural selection
*genetic drift
*gene flow
*antigenic drift
The two basic factors which are most important in determining the current appearance of a star are its mass and its stage of life. Stars are born with 75% Hydrogen and 25% Helium, with no more than 3% of that being heavier elements. A star burns its supply of elements over its lifetime, the larger the mass of the star then the greater it's brightness, luminosity and surface temperature will be. Dependant on the stage of the star's life, the color of the light will change.

Anthropology
Explanation:
this is the answer hope it helps you
Answer:
the Devonian ended with a series of glaciations and extinction events, the early Mississippian saw the Earth in a greenhouse climate state with warm temperatures over much of the globe. Gondwana continued its northward drift and collision with Euramerica, building the Appalachian Mountains.
The Mississippian culture was a Native American civilization that flourished in what is now the Midwestern, Eastern, and Southeastern United States from approximately 800 CE to 1600 CE, varying regionally. It was known for building large, earthen platform mounds, and often other shaped mounds as well.The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley. The Mississippian was a period of marine transgression in the Northern Hemisphere: the sea level was so high that only the Fennoscandian Shield and the Laurentian Shield were dry land.

Answer:
The correct answer is "vacuole"
Explanation:
The vacuole is an organelle found in most plant cells that serves to isolate substances that could be harmful for the cells and maintain pH equilibrium. Vacuoles have no particular form or shape, however they can be identified for looking like a bubble of considerable size. In the attached image it can be seen that the organelle labeled A corresponds to a vacuole for its size and bubble like form.
