Adot is drawn every second to show the position of a toy car coasting up a ramp. which statement best describes the motion of the car?

it is slowing down because less distance is covered every second.

the car is stationary, then slides back down because the ramp is so steep that it can’t coast up at all.

it is speeding up because more distance is covered every second.

the speed is constant because the distance between the dots remain the same.

How does secondary succession differ from primary succession?

What form of anesthetic was used for field surgery

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).
