Lori is learning about two parts of the rock cycle: weathering and erosion. She needs to explain how
weathering and erosion are different. Which of the following correctly describes the difference
between weathering and erosion?
O Weathering is the breaking down of rocks; erosion is the movement of weathered materials.
Weathering is the movement of rocks by wind; erosion is the movement of rocks by water.
Weathering is the formation of rocks from lava; erosion is the weathered materials from an area.
Weathering is when rocks change from one type of rock to another; erosion is when rocks are broken down.

This is the main structural axis of the plant that supports leaves, flowers and fruits; transports fluids; stores nutrients and produces new tissue.

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).
