In lab, imagine that you are given a section of the aquatic plant, elodea, to observe. as part of your observation, you prepare a wet mount of elodea, and add a 20% nacl solution to your slide. what should you expect to see when you observe this slide through the microscope?

You are expected to see the movement of the water trhough a plasmatic membrane.  

Explanation:

When we put a cell in different solutions , whit different concentrations, we can observe modifications in the protoplasm.    When a cell it´s in the presence of a salin concentrated solution (hipertonic), the water goes out the cell trhough the plasmatic membrane and this phenomenon its called plasmolisi.  

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

what? are the statements?
