1. Osmosis and diffusion (simple diffusion) are examples of passive or active transport? How do you know?

While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules.

Explanation:

Passive transport.

Explanation:

Osmosis and diffusion because a single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

this transfer is call conjunction

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.
