Assume that an apple contains 22 g of carbohydrates and has no fat or protein. The typical energy value for carbohydrates is 17 kJ/g or 4 kcal/g. How much energy, in kcal, is present in the apple?

The answer to your question is 88 kcal

Explanation:

Data

mass of carbohydrates = 22 g

Energy = 4 kcal/gal

Total energy = ?

Process

To solve this process use proportions and cross multiplication

                4 kcal 1 g

                 x         22 g

                 x = (22 x 4) / 1

                x = 88 kcal

This apple contains 88 kcal

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.

the growth of the plants is affected by the heat of the light. what is the student doing?
