Yes. Found in most animal cells and plant cells. It is responsible for cell respiration and the release or storage of energy in readily useable form.
<h2>
Answer</h2>
Stimulus ➡ Touch Receptor ➡ Sensory Nerve cell ➡ Relay nerve cell ➡ Muscle ➡Response
<h2>
Explanation</h2>
- When a body touches a hot or very cold body, a stimulus is generated.
- Touch receptors convert this stimulus into a nerve impulse and transmit it to the sensory neurons located in the spinal cord (CNS) via peripheral nerves.
- The impulse travels across a synapse to relay neurons
- Relay neuron passes impulse across the second synapse to motor neurons.
- Now impulse travels along motor neuron to reach the effector (muscle)
- Muscle contract and hand is withdrawn quickly (Response)
Answer:
The plants took in more CO2 and 'exhaled'/released oxygen. This occurs during photosynthesis, so we can therefore deduce photosynthesis was occurring
