Tobias has mononucleosis. mononucleosis is a disease that tires and weakens the body. it is caused by a contagious virus that is transferred through direct contact. which would be the best explanation of how tobias contracted mononucleosis?
tobias never exercised and was more susceptible to the virus.
as a male, tobias has a better chance of getting mononucleosis.
tobias inherited the gene from his parents.
tobias drank from a water fountain that was contaminated.

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.

i think the answer is 95 hope this
