Which of the following would be the best method to extend the above investigation? Repeating the experiment by disjoining the hooks of the spring balances. B. Repeating the experiment using non - identical spring balances. C. Repeating the experiment by applying different forces. Repeating the experiment by holding the spring balance vertically to verify if the results are the same.​

Scientist wanted to formulate a pool to attack a specific type of bacteria that infects with you. what biological component would be best to use as a model for the pills function?

20 the compound al(nh3)2 has atoms of nitrogen.

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).
