Answer:
Chemical reaction
Explanation:
Chemical changes happens when a substance combines with another to form a new substance (or unexpected color, temperature or smell), called chemical synthesis or, alternatively, chemical decomposition into two or more different substances

Answer:
The correct answer is option (C) "After splitting ATP, a protein changes shape to pump ions across a membrane".
Explanation:
Adenosine triphosphate (ATP) is an organic chemical molecule considered the "molecular unit of currency" of intracellular energy transfer, for the high level of energy that is released when ATP is breakdown into adenosine diphosphate (ADP). ATP provides energy to drive many processes in living cells. One example of how the chemical potential energy of this molecule is turned into work is that after splitting ATP, a protein changes shape to pump ions across a membrane. The energy of the splitting of ATP into ADP will provide energy for the protein being able to change shape, resulting in pumping ions across a membrane.
<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- Muscle contract and hand is withdrawn quickly (Response)
