PLEASE HELP NO I AM NOT LOOKING AT A LINK SO PLEASE DO NOT SAY LOOK AT ONE . when it is seen from above. In these diagrams, the sunlight is coming from the left, as shown by the
arrows. Which diagram is accurate and why?
a
Diagram A is accurate because the Moon is almost as far as it can be from the sun, so
almost none of the Moon is lit by the sun.
b
Diagram B is accurate because the half of the Moon that is facing the sun is lit by the sun,
and the other half is dark.
с
Diagram C is accurate because the whole Moon is bright as long as there are no shadows
covering parts of it.
d
All three diagrams are sometimes accurate because the Moon has some lighter-colored
rock and some darker-colored rock, and the half of the Moon with the lighter-colored rock
rotates to face different directions.

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).
