The marianas trench is a result of
a. oceanic crust to oceanic crust collision
b. oceanic crust to continental crust collision
c. continental crust to continental crust collision
d. diverging oceanic plates

b. oceanic crust to continental crust collision

Explanation: Oceanic plates are heavier than continental plates. When they collided the oceanic plate went down.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
