With higher levels of dissolved carbon dioxide in ocean water, the water becomes more acidic.  If low levels of carbon dioxide are absorbed by the oceans, would shellfish that can be easily killed by acidic water be more likely to die or less likely to die??
less likely to die?

We also saw that adding resistors to a series circuit increases the total resistance of the circuit, causing the current to decrease.  Jim loves to build circuits. One day he builds a circuit that has more resistors then any other circuit he has built. Since the circuit has more resistors the amount of current in the circuit is reduced or increased?
reduced
