PCBs intended for extreme environments often have a conformal coating, which is applied by dipping or spraying after the components have been soldered. The coat prevents corrosion and leakage currents or shorting due to condensation. The earliest conformal coats were wax; modern conformal coats are usually dips of dilute solutions of silicone rubber, polyurethane, acrylic, or epoxy. Another technique for applying a conformal coating is for plastic to be sputtered onto the PCB in a vacuum chamber. The chief disadvantage of conformal coatings is that servicing of the board is rendered extremely difficult.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The conformal coating can prevent leaking, shorts, and what other type of moisture damage?
Ah, so.. corrosion

Jesus' death and resurrection underpin a variety of theological interpretations as to how salvation is granted to humanity. These interpretations vary widely in how much emphasis they place on the death of Jesus as compared to his words. According to the substitutionary atonement view, Jesus' death is of central importance, and Jesus willingly sacrificed himself as an act of perfect obedience as a sacrifice of love which pleased God. By contrast the moral influence theory of atonement focuses much more on the moral content of Jesus' teaching, and sees Jesus' death as a martyrdom. Since the Middle Ages there has been conflict between these two views within Western Christianity. Evangelical Protestants typically hold a substitutionary view and in particular hold to the theory of penal substitution. Liberal Protestants typically reject substitutionary atonement and hold to the moral influence theory of atonement. Both views are popular within the Roman Catholic church, with the satisfaction doctrine incorporated into the idea of penance.

Ah, so.. unanswerable

Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.

Ah, so..
Melatonin
