Soil holds water that would have run off the roof.
Explanation:
A rooftop garden has the ability to reduce heat by up to 7ºC, in addition to promoting a beautiful and pleasant look.
First, a rooftop garden has plants that, in addition to releasing water vapor into the atmosphere, refreshing the environment, have the ability to increase the humidity of the place. The presence of soil also promotes the reduction of temperature, this is because the organic material contained in the soil and the roots of the plants allows the water that would run off the roof to be trapped in the soil, promoting a refreshment to the place. Finally, a rooftop garden usually has light colors, these colors reflect a lot of solar energy and absorb little solar energy, limiting high temperatures.
Pepsinogen is an inactive enzyme which is activated into active digestive enzyme known as pepsin. It is a digestive enzyme which causes breakdown of proteins. Active pepsin causes cleavage of more pepsinogen molecule by a positive feedback loop and leads to increase in the concentration of active pepsin molecule.
Its concentration increases according the requirement in the body which is controlled by feedback system.
The answer would be d because limitation of models is basically about non realistic part of models that separate them from real life which is what d is saying.
