The Baleen whale is the largest animal on earth yet it survives by consuming some of the smallest organisms in the ocean. What must be true in order for the Baleen whale to be sustainable? There must be enough Phytopankton to support enough Krill to sustain the whale.

The number of Krill is the only thing that matters in the environment because Krill are photosynthetic.

The number of Krill is the only thing that directly affects the whale because its the only thing the whale eats.

The whale can easily find other sources of food in the ocean to sustain itself.

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).
