Explanation:

The difference between replication and transcription, is that in the replication process the DNA is making more copies of itself and in transcription, the DNA is being copied into RNA. DNA replication occurs in preparation for cell division, and transcription occurs in preparation for protein translation

When Timmy steps on the rose bush, the sensory receptor on his toe receives the stimuli, sends it the spinal cord through a sensory neuron which they initiates a response sent through a motor neuron to the muscle and he withdraws his leg in pain.

<h3>What is a reflex arc?</h3>

A reflex arc refers to the neuronal pathway which controls a reflex action.

A reflex action is an action which occurs involuntarily.

Examples of reflex actions include thhe following:

  • withdrawing the foot quickly when one steps on a sharp object
  • withdrawing the hand quickly when one touches a hot surface
  • the je_rking of the knee
  • coughing or sneezing, when irritants enter the nostrils.

Reflex actions do not need to involve the brain, hence they occur very quickly.

The path of a reflex arc begins with a sensory receptor which receives the stimuli, travels to the spinal cord  through a sensory neuron which they initiates a response that is sent through a motor neuron to an effector such effector such as a skeletal muscle.

In conclusion, a reflex arc is the path of a reflex action through the body.
