← HistoryWhich outcome occurs given cyclical submersion of Viking longship mooring posts due to tides?
A)Accelerated microbial degradation of wood✓
B)Increased galvanic corrosion of iron
C)Reduced tensile strength of rope
D)Enhanced barnacle colonization rates
💡 Explanation
Accelerated microbial degradation occurs because alternating wet and dry conditions permit fungal colonization activating aerobic respiration, rather than consistent saturation limiting oxygen availability; therefore organic material breakdown happens due to hyphal enzyme activity rather than osmotic preservation.
