Describe the four kinds of bases found in dna.

Will mark branliest. the theory of plate tectonics was developed with the contribution of scientists from many different disciplines. which of the following is a contribution from geophysicists?

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).

Energy stored in the bonds that hold together the atoms and molecules of all substances is called a. kinetic energy. b. electrical energy. c. mechanical energy. d. chemical energy.
