A scientist conducting an experiment quickly saw that she was not getting the results she expected. Instead of continuing to collect data, she went back to redesign the experiment until the data came out the way that the hypothesis predicted.
The scientist's work did not follow the scientific method. Which statement best explains why?
She followed the steps of the scientific method, but in the wrong order.
O She made improvements to her experimental design rather than keeping it the same.
O She failed to look at the data objectively by trying to get a desired result.
O She carried out multiple trials rather than carrying out one trial correctly.

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).
