<u>light caused the elodea plants to photosynthesize, releasing O2 gas</u>
Explanation:
Oxygen is a by-product of photosynthesis. In presence of light, water molecules are split into hydrogen atoms and oxygen gas. The elodea plant is photosynthetic in nature. Later, the hydrogen atoms combine with carbon dioxide to form simple sugars like glucose in the dark stage.
Drawn bow because the flexing of the bow and the increased tension in the bow string contain the energy expended by the archer’s muscles transferred to the bow. The energy is transmitted to the arrow when then it’s released. All this is mechanical energy.
The other items in the list have potential electrical energy (battery), locked energy in the nutrients released during digestion (bun), electromagnetic energy (sun).

Answer:
Melanin is responsible for black colour of hair.
Explanation:
Hair is black in colour because it is determined by the amount of a pigment present in hair is called melanin. If eumelanin which is a type of melanin, present in hair, it gives people black or brown hair. If the receptor is not activated or is blocked in the hair, then melanocytes make pheomelanin instead of eumelanin and then the black or brown hair colour did not occurs so we can conclude that melanin is responsible for black colour of hair.
