Contraction of skeletal muscle fibers is stimulated by what type of neuron?

Motor neuron

Explanation:

A motor neuron is a neuron that is involved in a specialized kind of chemical synapse known as the neuromuscular junction. Within this synapse, the motor neurons terminal axon release the neurotransmitter acetylcholine, which induces muscle contraction via binding of post-synaptic receptors present on the muscle fiber.

i think its c. amphipod

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
