Histamine binds to the h1 g-protein-linked receptor to initiate the itchiness and airway constriction associated with an allergic response. if a mutation in the associated g-protein’s alpha subunit prevented the hydrolysis of gtp how would the allergic response change?
more severe allergic response compared to normal g-protein signaling.
less severe allergic response compared to normal g-protein signaling.
no allergic response.
no change compared to normal g-protein signaling.

answer; /// i believe the name your looking for is called (plaque)or check good luck

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
