When tiny ice crystals in clouds stick together to form snowflakes, the result is snow. If enough crystals form a clump, they'll become heavy enough to fall to the ground. When temperatures are cold and moisture in the form of tiny ice crystals exists in the atmosphere, snow forms.
An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested the experimentation. The results of experimentation lead to changes in scientific knowledge.
Answer is: c
"the light colored moths could not survive"
Answer:
Not being able to adapt creates competition from those who can adapt. This is called the survival of the fittest. New predators and loss of habitats create environmental pressures that can limit the growth of a population and lead them to extinction if they are unable to adapt. The faster the change occurs, and the more drastic the change is with respect to the way that species lives, the more likely it is that the species will not be able to adapt in time and may disappear. This is also called Natural selection.
