Select the correct text in the passage. which statement is a hypothesis? jada decides to investigate the effectiveness of hand sanitizers compared to soap. she says that hand sanitizers are as effective as soap in destroying bacteria. many sanitizers have alcohol as their main component. she performs a study in which people use sanitizers for one week and then soap for another week. she then examines the bacterial count.

The second statement is a hypothesis.

Explanation:

A hypothesis is an idea or the assumption that is presented so that it can be examined or tested to check if its true or not. In any of the scientific process, the hypothesis is made before any proper experiment or research has been done, apart from basic knowledge.

Jada also made an assumption about the effectiveness of soap and sanitizers before any research.

Thus, the second statement is a hypothesis.

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.
