Question

"The production of this hormone is high at night and low during day time​

Answer 1

Answer:

Night-time levels of melatonin are at least 10-fold higher than daytime concentrations. In addition to its circadian rhythm, melatonin levels also have a seasonal (or circannual) rhythm, with higher levels in the autumn and winter, when nights are longer, and lower levels in the spring and summer.
