C. cell body encapsulate the nucleus and the other parts of a cell
The correct answer to the question is : D) Be moving at a constant velocity.
EXPLANATION:
As per Newton's first laws of motion, every body continues to be at state of rest or of uniform motion in a straight line unless and until it is compelled by some external unbalanced forces acting on it.
Hence, it is the unbalanced force which changes the state of rest or motion of a body. Balanced force is responsible for keeping the body to be either in static equilibrium or in dynamic equilibrium.
As per the options given in the question, the last one is true for an object under balanced forces.
Convection currents occur in the magma drive plate tectonics. Here heat is generated from the radioactive decay of elements in the interior of the Earth, creating magma in the asthenosphere.
