b) Heart Rate: Our heart rate tends to be lower during sleep as our body is at rest.
c) Skin cell Replication: This process is indeed generally higher at night. Our body uses the time we sleep to repair and regenerate, including skin cells.
d) Cortisol: This is a stress hormone that follows a diurnal rhythm. It is typically higher in the morning after waking up and decreases throughout the day.
e) Both (a) and (c): As explained above, only (c) is correct.
