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:
A. The rock was made from more than one type of material
C. Sediments and other matter were deposited in layers before lithification
B) they work independently of one other
Answer: Lymphatic tissues
Explanation: Lymphatic tissues have various distinct configurational groups correlated to its specific purpose in the resistance of a particular infection reaction. Lymphatic tissues can be primary or secondary in basic features, the primary lymphatic tissues in humans being thymus and bone marrow. However, the lymphocytes are shaped from a long thin corroborative section of cells in the soft fatty material in the compartments of bones in which cells are generated and then distributed in the lymphatic tissue.
