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.
Answer:
This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain. In this activity you will explore the biomaginification of toxic chemical, mercury, through a simple marine food chain.
Explanation:
Many trees are evergreen so that plants can photosynthesize right away when temperature rise, many trees that have needle-like leaves which shape losses less water and sheds snow more easily than broad leaves waxy coating on needle-like prevent evaporation need-like leaves are dark in color allowing solar heat to absorbed many trees have branches that droop downward to help shed excess snow to keep the branches from breaking.
