Angelina is learning how to build circuits. She starts by connecting a light bulb to a battery with copper wires. In her studies
, she reads that the current flows due to a difference in potential energy in the system. Which statement describes what is happening to cause current to flow? A. Voltage is when current flows from lower to higher potential energy. B. Voltage is when current flows from higher to lower potential energy. C. Amperes is when current flows from lower to higher potential energy. D. Amperes is when current flows from higher to lower potential energy.
B. Voltage is when current flows from higher to lower potential energy.
Explanation:
Voltage refers to the difference in electric potential between two points. Current in the wire always flow from higher potential to lower potential due to voltage. At the electric source, voltage of current is high but when it moves through wire, the amount of current decreases when it reaches to the other end of the circuit. This is because of the resistance present inside the wire which causes heat energy and some of the current is lost.
The role of the effector(s) that result in a short-term
cellular change in a changing the activation state of an enzyme going from
inact to act this happens for instance when activating an enzyme to increase
sugar metabolism while Long-term cellular changes are generally the result of
changes in DNA transcription, i.e. a protein can be made to begin cellular replication
by activating the cell cycle.
