Answer: all of the above
Marine debris are among the biggest threats in the oceans nowadays. These include materials that are intentionally or unintentionally left in the ocean or any marine environment. Marine debris may include cigarette butts, food wrappers, bottle caps, straws, grocery bags and others.
Answer:
125000
Explanation:
Because it is halved and halved again.
Answer:
b) It produces electrical current spontaneously.
Explanation:
Cells capable of converting chemical energy to electrical energy and vice versa are termed Electrochemical cells. There are two types of electrochemical cells viz: Galvanic or Voltaic cells and Electrolytic cells. Voltaic cell is an elctrochemical cell capable of generating electrical energy from the chemical reaction occuring in it.
The voltaic cell uses spontaneous reduction-oxidation (redox) reactions to generate ions in a half cell that causes electric currents to flow. An half cell is a part of the galvanic cell where either oxidation or reduction reaction is taking place. Hence, the spontaneous production of electric currents is true about Voltaic/Galvanic cells.
