Carbohydrates and fats both 1.can be used as an energy source by organisms 2.can be bonded together to construct dna molecules 3.are made up of the glucose monomer 4.are monomers that can be made into large polymer chains

Option. "A"

Explanation:

Carbohydrates are the biomolecules that can be used as instant source of energy, once the carbohydrates are completely consumed by the body, it will further consume the fat molecules present in the body.

Carbohydrates (polymer) are consumed at first because they are easy to breakdown into simpler forms (monomer) whereas fat molecules require more energy to sort into simpler molecules.

Hence the correct answer is option "A".

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
