What do all vectors and scalars have? A. velocity
B. orientation
C. direction
D. magnitude

D. magnitude

Explanation:

Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.

A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."

Both scalars and vectors have magnitude.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
