Etienne created this Venn diagram that compares the characteristics of proteins and carbohydrates.

Explanation:

A Venn diagram is a diagram used to compare and show the similarity between more than two variables.

In the given question, the Venn diagram of carbohydrates and proteins has not been provided but the similarities and unique feature between them can be explained.

The similar features are:

1. Both are considered macromolecules.

2. Both are biomolecules used as energy molecules by body

3. Both perform various roles in the body like involved in the structural entity.

4. Both can be involved in body repair.

Unique features of Proteins and Carbohydrates:

1. Proteins act as cellular signalling molecules can act as an enzyme.

2. Carbohydrates act as a storage molecule by an organism like in the form of glycogen in animals and starch in plants.

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.
