Maria's doctor suspects she has reactive hypoglycemia. if her suspicions are correct, what would the level of her blood glucose likely be two hours after a high-carbohydrate meal? '

The reactive hypoglycemia is a condition, in which the hypoglycemia occurs withing 4 hours of having meal, especially the meal rich in the carbohydrate content.

The hypoglycemia is a condition, in which the blood glucose levels are declined to a level lower than the normal. in reactive hypoglycemia, the blood sugar level reaches below 70 milligram per decilitre.

So, the glucose level in Maria would lower than normal.

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.
