Due to a lack of predators, minnows have become overpopulated and eaten all of the algae and mosquito larvae, causing an extinction of these food supplies. Which other
species will now also be affected?

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).

During the final stage of the cell cycle, cytokinesis allows the cell to finish dividing, creating with copies of dna. can someone fill in the blanks?

Compare the two theories regarding the evolution of dinosaurs and then consider the cladogram above. although the two theories differ on the evolutionary path of dinosaurs, they agree that
