Answer: Stratigraphy and Biostratigraphy
Relative dating is a method of determination of age, in which one object or organism is compared with the other object or organism found in the heap of strata. It is a method for determining the relative order of the past events, without stating the absolute age.
Stratigraphy is a branch of geology that studies the relative position of the sediments and rocks in the strata with respect to the geological timescale. Biostratigraphy is the branch of stratigraphy which deals with the relative aging of fossils with respect to the strata in which these are found defining a particular period of geological time scale.

It is the Hypertonic Side. Osmosis applies a weight known as osmotic weight on the hypertonic side of a specifically porous film.
This implies osmotic weight should deliver a net development of water into a run of the mill cell that is encompassed by new water. On the off chance that that happens, the volume of a cell will increment until the point when the cell ends up plainly swollen. In the end, the cell may blast like an overinflated expand.
Well, the snails probably can't live in water, so what they needed was oxygen.
well it's not A, not C and not D.
The answer is most likely B
