[TG.05H]A specific location in Europe produces energy from fossil fuels and geothermal sources. The table below shows the amount of atmospheric carbon dioxide in the location from 1960 to 2000. Year19601970198019902000
Carbon dioxide level (in parts per million by volume)469448423393358

Based on the table, which of these conclusions is most likely correct about the location from 1960 to 2000?
There has been an increase in atmospheric temperature and decrease in acid rain.
There has been an increase in acid rain and decrease in atmospheric temperature.
There has been an increase in the use of geothermal energy and a decrease in the use of fossil fuels.
There has been an increase in the use of fossil fuels and a decrease in the use of geothermal energy.

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).
