Why is a temperature between 0 degrees celsius and 35 degrees celcius is still important

Protein activity rises as temperature  rises, and in turn, improves the rate of the reaction.

Explanation:

Warmth plays a vital role in biology as a way to control reactions. Protein activity rises as temperature  rises, and in turn, improves the rate of the reaction. This also means activity lowers at colder  temperatures. All proteins have a variety of temperatures when they are working, but there are some  temperatures where they work optimally. Using the latest Celsius mode of temperature measurement, we  can quickly discover how warm or cool it is. It was also known as Centigrade. This is because it is based  on the freezing and boiling points of water with 100 degrees within those temperatures. The main SI unit  of temperature is the Kelvin, which measures certain temperatures. However, for our everyday practice,  we use Celsius which is directly associated to kelvins. This is placed so that pure liquid freezes at zero  degrees Celsius and boils at one hundred degrees Celsius.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.
