These are all true except <span>"D. Natural selection usually causes a species to change suddenly," which is false. Natural selection and the subsequent changes to a species takes many thousands of years to have observable results. </span>
The given case is an example of reflex action.
The reflex action is an instant involuntary response to a stimuli, which can cause damage. The reflex action takes place through the processing of message through a reflex arc, this reflex arc lack the involvement of brain and the processing of the stimulus takes place in the spinal cord.
In this case, the sensory receptors detects the stimuli and transfer the message to the relay neuron present in the spinal cord through the sensory neuron. The relay neuron transfer the action message to the effector muscles present at the site of stimulus with the help of motor neurons.
Given below is a block diagram of reflex action.
Answer:
84m
Explanation:
Using the kinematics equation we can come up with the answer:

Where:
Vf = final velocity
Vi = initial velocity
t = time
In your problem we have the following given:
Vf= 0 m/s
Vi = 21 m/s
t = 8 seconds
The Vf is zero because the car stopped. The distance given in this case is not useful in determining the car's distance so we will solve it. So just fill in the equation with the given:

Thankfully, the deer was not hit!
