During the first one to two months of life, infants are incapable of deep sleep (they do not have trouble falling asleep but they do not generally stay asleep for very long stretches). This happens because infants can’t make the difference between night and day - they do not yet have a circadian rhythm. Around six weeks, the hormone melatonin is produced (pineal gland) and it helps establish a normal sleep-wake cycle.

Answer:

Explanation:

The internal clock system in a newly born baby is not synchronized  with the 24 hour clock system of the real world and thus most of the newly born babies hardly sleep more than  4 hour at a time. The Circadian rhythms of  a fetus is synchronized with the mother's  heart rate and breathing when he/she is in womb. After birth a child has to develop its own circadian rhythms when exposed to sunlight and night frequently but this process takes time.

The rapid depolarization phase of the action potentials of myocardial contractile cells is due to which ion(s)? The rapid depola
fgiga [73]

Answer:

Na+ only

Explanation:

Depolarisation of membrane refers to the change in the resting membrane potential of the membrane of a cell which is usually -70mv to a more positive value.

This value changes when the positive ions move inside the cell which increases the positive charge inside the cell.

In the myocardial cell, the sodium ions move inside the cell which changes the potential towards the more positive side as a result of which the signals for contraction arises.

Thus, Na+ only is correct.
