Non-renewable natural resources like oil and natural gas take a very long time to form. that is one reason for the building of windmill farms that produce electricity from the wind's movement. what is another reason? 10 points to anyone who answers this question b) the energy produced on a windmill farm is much cheaper. c) the energy produced on a windmill farm is much more expensive. d) windmill farms produce energy without producing as much pollution

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).
