How do differences between individuals and environments affect natural selection?
Differences between individuals may affect differences in their average reproductive success, causing the variant traits of individuals that have greater reproductive success (fitness) to become more prevalent in a given environment than rival traits. As environments change, so may the traits that have a reproductive advantage change. This is natural selection.
What do studies indicate about very small populations?
the # of individuals in a population, or population size, can affect the population's ability to servive.

Is natural selection the only force that drives biological evolution?
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
What is an example of an open population in science?

How does Immigration and emigration and natality rate and mortality rate affect population?
Immigration and higher natality rates increase population, while emigration and higher mortality rates decrease it. Immigration brings in new individuals, boosting population, while emigration removes individuals, decreasing population. Higher natality rates lead to more births, contributing to population growth, whereas higher mortality rates result in more deaths, reducing the population size over time.
