An example of refraction<span> is when </span>waves<span> approach a straight shoreline at an angle. The part of the </span>wave<span> crest closer to shore is in shallower water and moving slower than the part away from the shore in deeper water. The </span>wave<span> crest in deeper water catches up so that the </span>wave<span> crest tends to become parallel to the shore.</span>
Most models can't incorporate all the details of complex natural phenomena. For example, when measuring distances around the Earth it's convenient to model the Earth as a sphere, but this doesn't incorporate variations in distance because of mountain ranges, valleys and other topological features the traveler must traverse. Incorporating these additional details would make the model too complex for easy use. Since models must be simple enough that you can use them to make predictions, they often leave out some of the details.
ALSO.
The conformation of molecules are based on probability. It fails to take into account the electronegativity of individual atoms. And it is ineffective in showing inorganic interactions with metals and such.
A they are non-cellular they can’t make their own energy and only living host cells have the ability to mutate
<em>The answer is Plant cells. Plant cells have large vacuoles.</em>
