<span>You'd have to add more detail to answer the first question. The paper color represents some trait of the beetles, maybe color. If some colors had more squares at the end then whatever that trait was, it was favored (either fewer of them died, or they had more babies). Picking up squares is death (maybe from predation) Adding squares is births (having babies) This is what natural selection is. Some traits are favored such that the beetles that have them are less likely to die and more likely to have babies. So, every generation, there are more of those types of beetles added to the population. Hope this helps.</span>

What is population density?</h3>
The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.
The population density equation below can be used to calculate the population density of a piece of land:
Population Density = Population/ Area
The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.

Well the cell membrane accepts nonpolar molecules, and O2 is nonpolar.
Answer:The answer is diffusion.
Explanation: Unicellular organisms excrete waste by diffusion.
Unicellular organisms are organisms that have only one cell. They are called single cell organisms because all their life processes such as reproduction, feeding, digestion, and excretion, occur in only one cell. An example of unicellular organism is paramecium.
Diffusion is the inactive movement of molecules from the region of higher concentration to the region of lower concentration.
