Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance
They are held together by weak hydrogen bonds
An ideal gas is a theoretical gas in which inter molecular forces do not exist among the molecules and the molecules do not occupy any space. A gas that does not obey ideal gas law are described as non ideal in behaviour. Gases that are most susceptible to non ideal behaviour are those that have attractive and repulsive forces among their molecules and whose particles have volume. Gases that exhibit non ideal behaviour has compressiblity factor ratio that deviate from 1.
Dogs, no matter what breed they are, they are all of the same species and therefore can breed with each other and create fertile offspring
I pray this helps you :)
