Answer: B) Population size is the total number of organisms, while population density is the total number of organisms within a given area.
Population size refers to the total number of organisms present in a population. On the other hand, population density reflects population size per unit area.
For example- In a population, if 200 individuals are living in 100 square meter of area.
Population size = 200
Population density = 200/ 100 = 2 individuals per square meter.
The answer is natural selection.
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Darwin's theory suggested that there are variations
among individuals in a population and that these variations will help individuals to survive.

Answer:
Well the model above is showing all the planets in order from how close or far away they are from the sun and it also seems to show the scale of each planet compared to another.
Explanation:
As for the Evidence or why it is important to know this is because the scale and location of the planet to the sun directly effects everything about the planet, its Atmosphere, tempterue and rotaion. And the more we learn about all plants we can better underatand our own geological past behavior of its Atmostohere and futute clamatic trends.
