Which cell(s) must use ATP energy to move the molecules out of the cell? (Hint: When using energy by the cell molecules will move from Low to High) im not sure if its, both of them or a or b

Cell A

Explanation:

The process in cells that requires energy to transport the molecules from low concentration to high concentration is called active transport. During active transport, molecules move against the concentration gradient, from low to high concentration.

In the given diagram, cell A uses ATP energy to move the molecules out of the cell because the molecule concentration is high outside the side and molecules are moving from inside to outside that is from low to high concentration.

Hence, the correct answer is "Cell A"

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.
