Why is Parkinson’s disease is describe as degenerative disorder?

Parkinson's disease (PD) is a neurodegenerative disorder that affects predominately dopamine-producing (“dopaminergic”) neurons in a specific area of the brain called substantia nigra.

Explanation:

Many organisms dispose of excess body heat by evaporative cooling. The property of water termed as high specific heat is responsible for this adaptation.

Explanation:

Evaporating cooling refers to the phenomenon in which when water is heated it leads to evaporation due to which the heat present in the body gets removed.

Specific heat is the amount of heat required or lost to convert 1 g to 1 degree Celsius. This is one of the most important property of the water and this property of water is responsible for evaporative cooling mechanism.
