Answer:
The four-letter word which speaks to the ability of an organism to modify its behavior or actions to external stimuli is <u>Move.</u>
Explanation:
Movement gives organisms the ability to move away from or towards an external stimulus depending on whether it is a detrimental stimulus or a favourable one.
Examples of stimuli are:
- Light: All organisms respond to the presence of light. Some stay away from it and remain at sleep until the sun goes down. They are called nocturnal. Others gravitate towards it. Plants always grow towards light.
- Temperature: Some organisms favour cold environments, other the temperate parts of the earth
- Sound: The sound of a carnivorous animal such as the lion will put a deer to flight. The sound of a mother hen calling out to her chicks will attract them to her.

<u>Answer:</u>
It functions in a way similar to ATP as a rechargeable battery, because it can store energy and then release it.
<u>Explanation:</u>
- ATP (Adenosine triphosphate) is an energy component in the cell as it provides energy required for various purposes of activities in the cell hence it is termed as the “currency” for energy.
- ATP produces ADP that is converted into the energy for the flow of cellular activities and then ATPs can again be reused many times.
- As in batteries, ATP can also be recycled and recharged to get the required energy several times.
