Answer: e. mindfulness
<span>When alpha waves are dominant in your brain (8-12 Hz), you will feel very relaxed. This happens when you are waking up in the morning.</span>
Alpha waves can be created thru aerobic exercise. Progressive relaxation also increases alpha waves. Biofeedback<span> is a technique used to create alpha brain waves also, in order to prevent or treat conditions like headaches, chronic pain, and high blood pressure. </span>
<span>However, alpha waves are strongest when you are practicing mindfulness or meditation with your eyes closed.</span>
<span>Guided imagery and cognitive restructuring are not associated with brain's production of alpha waves.</span>
Answer:
Option (1).
Explanation:
Action potential may be defined as the change in the cell potential that helps in the transmission of the nerve impulse. The resting membrane potential of the cell is -70mV.
The depolarization phase of the cell has membrane potential towards more positive. After the depolarization phase, the sodium channels are closed and potassium influx occurs that causes the re-polarization of the cell. This activity of the re-polarization is not the consequence of the closing of the inactivation gates.
Thus, the correct answer is option (1).
Answer:
D
Explanation:
One cycle of the Krebs Cycle consumed 2 water molecules.
The first and the fourth test tube exhibit a redish/brown color and the second and third test tubes show a dark blue/black color.
This variation exists due to the fact that amylase was added to the first and fourth test tubes. Amylase acts upon starch and breaks it down to simpler molecules. Therefore, when the IKI solution is added to check for the presence of starch, a negative result is shown. Meanwhile, the starch in the second and third test tubes remained and the IKI test showed a positive result for the presence of starch.
