Oceans have absorbed approximately one-third of the excess carbon dioxide that humans have added to the Earth's atmosphere so far. This has slowed the progression of global climate change, but it has led to .

E) increases in growth of coral reefs

The body is protected against harmful flu viruses by

How does this experiment explain why it is often milder in areas such as coastal maryland while areas such as kansas or iowa have more extremes in temperature

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).
