Which items are used as types of models check all that apply
a diagram
b illustrations
c observation
d reports
e structures

A. Diagram ,E. structures,  B. illustrations, C. observation D. reports

Explanation:

A scientific model could be a diagram or a structure. The diagram or a structure illustrate clearly by observation and finally reports are made on it. The diagram and structures are scientific tools which describes something about it. Simple concept can be learn  by observing a model in a scientific laboratory. Diagrams are extremely helpful tool in describing the phenomena and and its role in the world are in the human body Mathematical and computational tools are also associated with this models.Reports are the final step which tells something about the model

Option-A,B and E.

Explanation:

The models are the simplified explanation of a complex process and mechanism occurring in nature.

The reason for this simplified explanation is that these models involve the 2 D and 3 D representation in which diagrams and illustrations are used in 2-D explanations whereas the physical structure provides 3-D explanations.

These models are used by the scientific people to explain the complex process to other laymen.

Thus, the selected options are correct.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
