How do tides differ from waves and gravity?

a. tides are driven by the gravitational pull of the sun and the moon.
b. tides are reliant on a centrifugal force.
c. tides are created from drag friction.
d. tides are surface tension.

A: Tides are driven by the gravitational pull off the sun and moon.

That is the answer. I'm sure

A. Tides are driven by the gravitational pull of the sun and the moon.

Explanation:

Tides are rise and fall in level of seas and oceans. This happens due to the gravitational pull of the sun and the moon. The effect is maximum when the two align in a straight line and minimum when the two align at right angles.

Spring tides occur during new moon and full moon phase when the sun and the moon align in straight line. Highest high tides and lowest low tides occur.

Neap tides occur when the sun and the moon align at right angles. The tidal range is smallest due to this alignment.

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

only about ten percent of the energy at one trophic level is passed on to organisms at the next trophic level. the remainder of the energy is used in life processes or lost as heat.
