A consumer wanted to know which type of paper towel is most absorbent. If she conducted an experiment to discover this, the independent variable would be the
and the dependent variable would bethe brand of paper towel

The independent variable could be:

Explanation:

The independent variable has to be something that can be quantitatively measured and that will give us an accurate depiction of how well the different paper towel brands can absorb things. Hence, an answer like "amount of water absorbed" is not quite enough because we need to know what exactly we're measuring. Volume or area are both feasible options.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

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.
