E Describe how increasing salinity afects the amount of fluid ejected each time a
contractie vacuole contracts. Calculate the water potential of an animal cell without
contractile vacuoles if water enters the cel and creates a solute potential of -2. Assume
that the pressure potential in the cell is 0

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

you're crazy : )
