According to the scenario, the time of the next high tide would be 8:30 p.m. Thus, the correct option for this question is C.

High tide may be defined as the tide when the water is at its greatest elevation from the ground level. The tide gets significantly high when the sea or ocean is closer to the Moon. It disturbs the life of all sorts of aquatic animals.

According to the context of this question,

The time at which an observer recorded the first high tide = 7:12 a.m.

The time at which an observer recorded the second high tide = 7:38 pm.

The time at which an observer recorded the third high tide = 8:04 a.m.

So, the difference between the time of all these tides is found to be 12 hours and 26 minutes.

Therefore, the next and fourth high tides would be observed after 12 hours and 26 minutes at 8:04 a.m which is 8:30 p.m.

Therefore, the time of the next high tide would be 8:30 p.m. Thus, the correct option for this question is C.

Answer:

Please find the explanation to how cells in the kneecap get rid of waste products of respiration.

Explanation:

Cellular respiration is the process by which glucose molecule is broken down to release energy in form of ATP. The major waste product of this process of respiration, however, is Carbon dioxide (CO2).

Since all cells in a living organism like human, whether kneecap cells or brain cells, undergo respiration, CO2 is excreted out of all cells via DIFFUSION i.e the CO2 molecules move out of the cell where it is in high concentration into the bloodstream, where it is in low concentration via the cell membrane. The blood transports the CO2 waste to the alveoli of the lungs, where it is finally exhaled out of the body.
