An environmental change than an animal must respond to could be a change in climate which affects humidity and temperature.  If it could not adapt, it will die out and only the ones that could adapt will live on.  This is called natural selection

Answer:

Temperature is the most important environmental change that an animal must respond to in order to keep a stable internal environment. A right internal temperature of the body is crucial for working of enzymes present in the body and if these enzymes do not get the right temperature they will not work properly and the animal will dye.

There are two types of animals cold-blooded and warm-blooded. Cold-blooded animals require sun energy to raise their body temperature but warm-blooded animals like mammals auto regulate their body temperature which requires lots of energy.

If an organism could not adapt to an external environment like temperature then it will dye soon or later because natural selection eliminates those organisms which are unable to adapt the changing environment.

Tatiana [17]

The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.

Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.

<h3>What are Skeletal muscles?</h3>

Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.

Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement.

While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.

Therefore, it is well described above.
