The graph of the position of a DNA molecule (on the vertical axis)vs.time (on the horizontal axis)is a straight line that does not go through the origin and does not have a slope of zero.Which statement is true?
A)Its speed is always zero.
B)Its velocity is constant.
C)Its position is always zero.
D)Its acceleration is not zero.

Since the graph is a straight line that does not go through the origin and does not have a slope of zero, the velocity is constant. However, since the slope is not zero, the acceleration is also not zero. The options A and C are incorrect because if the position is always zero, then the graph would be a horizontal line at the origin, and if the speed is always zero, then the graph would be a point on the y-axis.
