Manuel's teacher asked the class to make a wet mount slide of their cheek cells. manuel made his slide and placed it on the microscope stage. then he got ready to view his cheek cells by following these procedures. 1. looking through the eyepiece, manuel adjusted the diaphragm so field of vision was lit. 2. manuel looked at the stage from the side and lowered the body tube so the high power objective was almost touching the slide. 3. looking into the eyepiece, he very slowly turned the coarse adjustment to bring the cells into focus. what suggestion would you make to manuel to correctly use the microscope to view his cheek cells? a) close the diaphragm b) start with the low power objective c) do not look at the stage when lowering the body tube d) start with the body tube raised and lower it while looking through the eye piece

B

Explanation:

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.
