Answer:
Light travels in a straight line until something alters its path. Here are three ways light's path can be altered: it can be refracted, reflected, or absorbed.
Materials such as a mirror or aluminum can reflect light.
Materials such as water or glass can refract light.
Materials such as coal or clack paint can absorb light.
The main function of the respiratory system is to allow the exchange of gases between the atmosphere and the lungs.
Hence,the only structure that carries out this function is the alveoli as other structures such as the nose,trachea and pharynx transport gases to the alveoli just so that it can can out its function.
Answer:
The difference is:
a) Positive feedback increases a change while negative feedback reduces a change.

c) Positive feedback break down the homeostasis while negative feedback maintain the conditions of homeostasis.
d) Positive feedback has less frequent mechanism while negative feedback has more frequent mechanism.
e) Positive feedback enhances change while negative feedback resists change.
f) Positive feedback has a wider range while negative feedback has a narrow range.
