What is the relationship between the number of motor neurons recruited and the number of skeletal muscle fibers innervated? a) motor neurons always innervate thousands of skeletal muscle fibers. b) a skeletal muscle fiber is innervated by multiple motor neurons. c) typically, hundreds of skeletal muscle fibers are innervated by a single motor neuron. d) a motor neuron typically innervates only one skeletal muscle fiber.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
