What happens to the carbon dioxide produced by cellular respiration? a. it is reused by the body as glucose b. it is excreted from the body as solid waste c. it is excreted from the body as liquid waste d. it is breathed out of the body by the lungs

The right answer is D

Carbon dioxide (CO2) accounts for 77% of human-induced greenhouse gas (GHG) emissions. It results mainly from the burning of fossil fuels and the change in land use (agriculture and deforestation) and in a small proportion of the breathing of living beings.

Respiration is gaseous exchange resulting from inhalation and expiration of the air (more precisely, CO2 carbon dioxide release and oxygen O2 absorption) and cellular respiration that allows, by degrading glucose through oxygen, to obtain energy.

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.
