What could be a result of an injury to the dorsal column?
a.
loss of sensation to pressure and touch
b.
loss of control over all involuntary movements
c.
inability of the body to maintain homeostasis
d.
inability to regulate the sleep-wake cycle
e.
loss of motor control

A.  loss of sensation to pressure and touch

Explanation:

Posterior column-medial lemniscus pathway  also known as  the dorsal column–medial lemniscus pathway (DMLP) is a pathway involved in recognition of sensory simulations and is found in central nervous system.

It is involved in conveying  different sensations like like touch and vibration from skin and joints. Therefore, it can be said that the pathway plays significant role in perception of sensory information from different parts of the body. If any damage occurs to the pathway it can  result in loss of sense of touch and vibration which is ultimately a lack of ability of a person to sense a touch or pressure in the body.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
