nucleic acids and water
oxygen gas and fats

carbohydrates. nucleic acids and water. oxygen gas and fats. NOT NUCLEIC ACIDS AND WATER

fats and proteins

Explanation:

The fat molecules are the important biomolecules which consists of carbon and hydrogen atoms. The arrangement of these atoms make the structure of fat hydrophobic which is soluble in organic solvent and insoluble in water.

The proteins are also the vital metabolic biomolecules some of them are regulatory others can be structural in nature. They consists of hydrogen, oxygen and carbon. These biomolecules also contains sulfur, phosphorus and nitrogen in composition.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
