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

The correct answer would be a loss of sensation to pressure and touch.

The dorsal column-medial lemniscus pathway abbreviated as DCML refers to the sensory pathway of the central nervous system (CNS) which transmits sensations of vibration, fine touch, proprioception, and two-point discrimination from the skin as well as joints.  

Thus, injury to the dorsal column would result in the loss of sensation to touch and pressure.

The answer is A: loss of sensation to pressure and touch

Explanation:

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
