Explanation:
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.

It’s A, the cell must be a eukaryotic because it has a cell membrane and a cell wall.
Pressures can change the state of an environment – e.g. water quality reductions – which then causes impacts such as the loss of biodiversity and ecosystem services provision.
This would mean that it went 5 km for 10 seconds
5 x 10= 50km during that period of time
