Phasic receptors:
a. are quick to adapt to a particular stimulus intensity.
b. slowly decrease the frequency of action potentials generated to a constant stimulus.
c. are attune to parameters that the body must continuously assess.
d. once threshold is reached by a stimulus will always generate action potentials.
e. change their sensitivity in phases going from slow to fast.

a. are quick to adapt to a particular stimulus intensity.

Explanation:

Phasic receptors are the one that first generates an action potential in response to the stimulus. However, they adapt to that intensity of the first stimulus and reduce signaling. Slowly, they even stop signaling irrespective of the presence of stimulus of the same intensity.  

This is the reason that we get adapted to the specific odor such as gas leakage after some time even if the leakage continues.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

i was thinking 4.0 v hope this
