List two examples of how chemical or nuclear energy can be transformed

Chemical energy can be transformed into electrical energy and mechanical energy.

Explanation:

Chemical Energy transformed into Electric Energy - widely exploited by batteries. The chemical reactions that are taking place in these devices can be used as a direct source of electrical energy. Some may be reversed and some non - reversible are called rechargeable. Never attempt to recharge regular batteries as there may be an explosion with burns and material and personal damage. Chemical energy transformed into mechanical energy: An explosion is always accompanied by a shock wave. The shockwave is nothing but the air being moved very quickly, a kind of supersonic wind that is accompanied by a crash. Explosives are an example of this type of transformation.

The main role of dna in the  cell is the long-term storage of information. it is often compared to a blueprint, since it contains the instructions to construct other components of the  cell, such as  proteins  and rna molecules.the main function of rna is to carry information of amino acid sequence from the genes to where  proteins  are assembled on  ribosomes  in the  cytoplasm. mark brainliest, my work is good.
