The diagram below shows the movement of water on Earth. The picture shows the oceans on the world map. Ocean water is shown flowing from east to west, from the Pacific Ocean past Australia and the Indian Ocean and around the southern tip of Africa. The ocean water then flows north along the coasts of Africa and Europe. A point in the water in the north is labeled A. The water finally turns south where the Atlantic Ocean meets the Arctic Ocean. The ocean water flows south along the coasts of North and South America. A point in the water in the south is labeled B. The water then flows from west to east, past Antarctica and Australia, before finally flowing north through the Pacific Ocean. Which of these statements best explains why water flows from point A to point B? The salinity at B is more than at A. The wind velocity at B is more than at A. The temperature at A is more than at B. The water density at A is more than at B.

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).
