The best topsoil will be found in the tropical region.
<h3>What are tropical regions?</h3>
They are regions of the world located within the two tropics - tropic of Capricorn and tropic of Cancer.
The region is characterized by adequate precipitation and relatively warm annual temperature. Thus, there is a high diversity of plants and animal species.
Tropical forests are known as the biodiversity hotspots of the world. This means that the soil is rich enough to support a diverse species of plants as compared to other regions of the world.

Answer:
excitable
Explanation:
All muscle types will respond to an electrical stimulus because all muscle cells are excitable.
Excitability is response of muscle to signal which delivered through the motor neuron.
Excitability is stretching of muscles.
The contraction and relaxation of muscle occur in following way:
Muscle contraction begins with signal. The contraction occur when nervous system send signals. The impulse which is called signal is travel through a motor neuron.
The whole process include following three steps:
1) Message is traveled from nervous to muscular system and trigger the chemical reaction.
2) This chemical reaction causes the muscle fibers to reorganize in such a way that shorter the length of them which is called contraction.
3) when this signal is no longer remain , reverse chemical process occur and muscles relax.
