Ms. Rivera is demonstrating an experiment that includes the use of a compass. A compass has a small magnet that rotates to align with Earth's magnetic field. This small magnet of the compass is called a needle. The model below shows the experiment that Ms. Rivera is demonstrating. What will most likely happen to the compass needle when the switch is closed and the circuit parts are connected to the battery?

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
