Answer:

D:Genetic material must have a complex structure.

**Answer:**

v(t)= (d/dt)x(t)

**Explanation:**

The instantaneous velocity of an object is the limit of the average velocity as the elapsed time approaches zero, or the derivative of x with respect to t. Like average velocity, instantaneous velocity is a vector with dimension of length per time. The instantaneous velocity at a specific time point t
0 is the rate of change of the position function, which is the slope of the position function

x
