Edit
Viruses reproduce within the living cells of the host and use the cellular machinery to synthesize their own genome and other components. To gain entry into cells, they have developed a variety of mechanisms to introduce their genes and proteins into host cells.
If from the low tide to the high tide there was a break of 6h and 4m than the next tides will happen at the same rate:
8:35 + 6:04 = 14:39 = next low tide.
14:39 + 6:04 = 20:43 = next high tide.
Note that two same tides occur about 12h to 12h and 25m apart, and that is the case here:
14:39 - 2:31 = 12:08 hours apart
20:42 - 8:35 = 12:07 hours apart.
Hope it helped,
Happy homework/ study/ exam!
