This phenomenon is referred to as receptor situations.
Answer:
Island finches did not have beaks of the same size and shape
Explanation:
This is the evidence of variation, and therefore proof that the finches were able to survive the selective pressure by adapting their beaks to different feeds. Therefore finches that were able to adapt adjusted their beak shapes to the selecting pressure 'feeds' in the environment, and are naturally selected, and therefore adapted and evolved with time .While those without the surviving beaks lost out.
Thus changes in selection pressure, necessitated corresponding change in the beaks shape for adaption to survive( due to variation, ) and therefore natural selection for evolution
Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation
processes occur to help species survive and thrive in the ecological balance of
life. Structural adaptations are physical features of an organism that adapted
through time. An example of this are the bills of a bird and the fur of bears
that they generally need for their survival; birds for hunting, and bears to
protect them from low climate areas.

Functional or
Behavioral adaptations refer to particular things that an organism or organisms
do to survive. In the example above, behavioral adaptations that birds do is
through certain bird calls and migration, while bears hunt during warmer
seasons and hibernate during winter season. </span>
Answer:
Oil can be burned to heat water, using the steam to generate power. Or, oil can be burned under pressure to produce exhaust gasses.
Answer: Coal is ranked depending on how much carbonization it has gone through. Carbonization is the process that ancient organisms undergo to become coal
