Sandra examined some animal cells using a compound microscope. Under normal conditions, the cells have an approximate salinity of 1 M NaCl and resemble the slide shown in picture 1. If the cells are submerged in a 0.8 M NaCl solution, what will happen to the cells?
A.
Water will move into the cells and they will swell as in picture 2.

B.
Water will move into the cells until they swell and burst as in picture 4.

C.
Nothing will happen; they will look the same as in picture 1.

D.
Water will move out of the cells and they will shrink as in picture 3.

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
