Reflex action refers to the response to a stimulus, while reflex arch refers to the path taken by the reflex action.
<h3>What is the nervous system? </h3>
1. Low oxygen levels are detected by sensory receptors in the arteries.
2. An impulse is produced by sensory neurons.
3. Certain parts of the brain get an impulse from the central nervous system.
4. Motor neurons carry messages from the brain.
5. Isabel's respiration becomes more rapid.
Reflex actions are immediate, reflexive reactions to stimuli that limit bodily harm.
Therefore, it travels to the brain via the central nervous system and sends impulses via Isabel's motor neurons, which aid to speed up her breathing.

Hey there!
Here are your answers:
<u><em>1. The proper answer to this question is "the Sun".</em></u>

<em>Therefore the answer is the Sun.</em>
Here is your second answer:
<u><em>2. The proper answer to this question is "</em></u></span><u><em>photosynthesis".</em></u>
Reason:
<u><em>Photosynthesis is the process that plants use to change (convert) light energy into energy (that other organisms can use). For example a apple tree uses </em></u><span><u><em>photosynthesis to make apples for humans, and other organisms to consume for energy.</em></u>
<em>Therefore the answer is </em></span><span><em>photosynthesis!</em>
<em>To sum up the answers are:</em>
<em>1.Sun</em>
<em>2.P</em></span><span><em>hotosynthesis</em>
