Answer:
C. their predictions are not accurate every single time .
Step-by-step explanation:
Scientific models are considered technologies capable of providing research instruments that enable the understanding of theories and the world. Its main characteristics involve autonomy, representational power and the ability to promote relationships between scientific theories and the world, and can therefore act as powerful agents in the learning process, being considered a means and source of knowledge.
In short, scientific models like this are useful because they can help describe and predict natural behavior. However, these models are limited and their predictions are not accurate every time. An example of this is Dalton and Thompson's atom models, which did not represent the atom precisely as we know it today.
