Answer:
The correct answer is option b. "Alpha eventually replaced by theta".
Explanation:
Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves.

A
muscle that is lengthening while it produces tension is performing an eccentric
contraction.
<span>
Eccentric
contraction is the contraction that occurs when the load on the muscle
increases and at one point it reaches a stage where the external force on the
muscle is greater than the force that the muscle can generate. As a result, the
muscle is forced to lengthen due to the high external load.</span>
