The students decide to model how the motion of two plates occurs. Which statement best describes the ability of the model to predictyplate movement? A The motion of the plates cannot be modeled on a scale that is much smaller than the plates themselves. B The motion of the plates cannot be modeled by simplifying the factors that contribute to plate movement. C The motion of the plates can be modeled by including only the main factors that contribute to plate movement.

In my view, all factors are equally responsible for this.
A lever used to lift a heavy box has an input arm of 4 meters and an output arm of 0.8 meters. What is the MA of the lever?
Answer:
Mechanical advantage = 5
Explanation:
Given the following data;
Length of input arm = 4 meters.
Length of output arm = 0.8 meters.
To find the mechanical advantage;
[tex] Mechanical \; advantage = \frac {Length \; of \; 1nput \; arm}{Length \; of \; 0utput \; arm} [/tex]
Substituting into the formula, we have;
[tex] Mechanical \; advantage = \frac {4}{0.8} [/tex]
Mechanical advantage = 5

Explanation:
its A
The best explanation for the prokaryotic expression of a metabolic protein is repressor proteins can be activated and bind to regulatory sequences to block transcription.
