The structure of biomolecules controls their structure, properties, function, and relationships with other biomolecules. One of the most important relationships is between a given biomolecule and water. Which of the following statements is true about the relationship between a given class of biomolecule and water? Large carbohydrate polymers will not be soluble or stable in an aqueous solution.
If the outer surface of a protein contains a high density of non-polar amino acids, it can be water soluble.
Since lipid chains are hydrophobic, the presence or absence of water does not affect how they group.
Nucleic acids can hydrogen bond, which allows them to base-pair and to non-covalently bond with water.

littering streams           is the answer

i think that d. wind is the answer.   i missed the question when i answered a. currents.

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.
