Conservationists establish that the carrying capacity of a population of deer in an extensive geographical area is 945. the current population of deer is 1,100. what is likely to happen to the population of deer? a. the growth pattern will change from logistic to exponential. b. the minimal viable population for the deer will increase. c. deer from other populations will immigrate to find mates to reproduce successfully. d. the population will remain healthy, and its numbers will increase. the population size will drop until the numbers reach the carrying capacity.

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).
