Explain what the theme “form = function” means and how it applies to the function of different biomolecules. answer i really need i have a test coming up! ps-i will vote you brainiest.

The theme "form=function" represents the shape of the biomolecule that determines its function.

The theme "form=function" can be best understood by the study of proteins. Proteins are the biopolymer made up of the repeting subunits of monomers called the amino acids. Amino acids are the organic compounds made up of an amino group and a carboxyl group. In addition to this, they contain a functional "R-group" that determines the amino acid. These R-groups in the amino acids of a protein either attract or repel from each other giving a three dimensional structure to the protein which is critically important for its functioning.

Similarly, the cell wall of the plants are made up of the cellulose. It is a structural carbohydrate biomolecule responsible for providing rigidity to the cells and protecting them.

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.
