Pls help me, this is science btw.

(B) and (E)

Explanation:

It is not option (A) because it says that Lactobacillus is a kind of bacteria that harms you, not is good for you, and parasitic bacteria are harmful to you, so not (A).

Not (C) because it does not make any sense whatsoever.

Not (D) since that says that S. typhi has a mutualistic relationship, which is good for both organisms, which is not true in this case.

It is (B) because the harmful bacteria, S. typhi is a parasite to humans.

It is also (E) since that says that the Lactobacillus bacteria does share a good relationship with humans.

gold i'm pretty sure i might be wrong

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.
