Ocean tides are caused by the gravitation of the Moon. Currents can be
formed by the flow of tidal water around the continental plates, or by a
difference in water temperature between large ocean areas. Surface
waves are caused by the wind. Abnormal waves can be created by the
tectonic movement of plates around and under the ocean floor (tsunamis).
So as you can see, the answer is (C) Gravity

Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
the answer is a because if the model is based on experimental data it wont be good unless it has been tested.
