What could be a result of an injury to the dorsal column?
Mariulka [41]

Answer:

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.

Hope it helps!

Sort the labels into the correct bin according to the effect that gramicidin would have on each process.
EleoNora [17]
Remains the same: proton pumping rate, electron transport rate, rate of oxygen uptake
Decreases or goes to zero: Rate of ATP synthesis, size of the proton gradient
<span>(Gramicidin causes membranes to become very leaky to protons, so that a proton gradient cannot be maintained and ATP synthesis stops. However, the leakiness of the membrane has no effect on the ability of electron transport to pump protons. Thus, the rates of proton pumping, electron transport, and oxygen uptake remain unchanged.)</span>
