Forest rangers are genetically testing the deer in the forest after many were found dead. The tests determined that due to inbreeding, most deer have a genetic disease which decreases life expectancy. Based on genetic and mortality data, the rangers predict that the population of deer will be gone in 3 years. What initial concerns do the rangers most likely have?

There will be an increase in energy at the primary consumer level of organisms.

Energy available at the producer level will increase.

Less energy will be available mushrooms and earthworms.

There will not be enough energy to support the tertiary consumer population.

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).
