Answer: Anaerobic respiration or Fermentation
Explanation:
When we are engaged in intense physical activity such as running or riding a bike, the muscles need energy to function and they get this from aerobic respiration.
They will quickly run out of the oxygen required to sufficiently use aerobic respiration however and will turn to anaerobic respiration which can produce energy in the absence of oxygen.
As the body uses anaerobic respiration however, lactic acid is produced and builds up in the muscles. It is this lactic acid that leads to the muscles feeling sore.
I think the answer is fertility rate... but i could be wrong. good luck!
It helps with the worlds water supply.
It is especially important to monitor tides for people who rely on the sea for living - fishermen have to know the kinds of tides they are going to experience so as to decide whether to set off in search of fish or not. It is also quite important to monitor tides if there is some construction going on near the shore - for example, building bridges or docks, as when the tide comes, it may flood the whole thing. Scientists also study the tidal movements so as to better understand the circulation of the oceans.
Hope this helps! :)
