Answer:
-Histamine binds extracellularly to the H1 receptor.
-When histamine binds to the H1 receptor. the receptor undergoes a conformation change and binds the inactive G protein.
-Once the G protein is active, it binds to the enzyme phospholipase C, activating it.
-Histamine is likely hydrophilic.
When histamine encounters a target cell, it binds extracellularly to the H1 receptor, causing a change in the shape of the receptor. This change in shape allows the G protein to bind to the H1 receptor, causing a GTP molecule to displace a GDP molecule and activating the G protein. The active G protein dissociates from the H1 receptor and binds to the enzyme phospholipase C, activating it. The active phospholipase C triggers a cellular response. The G protein then functions as a GTPase and hydrolyzes the GTP to GDP. The G protein dissociates from the enzyme and is inactive again and ready for reuse.

The correct answer is B. Unproductive wells.
The possible long-term consequences of groundwater overdraft is the unproductive wells.
Groundwater overdraft is known to occur when the ground water which is used exceeds the amount which is in the aquifer.
Groundwater results in reduced in supply of water reason being groundwater pumping costs, groundwater contamination, aquifer depletion or cost of well deepening.
Answer:
Wild Fires
Explanation:
Wild Fires are caused many factors including discarded cigarettes . These can be prevented when people stop to smoke in the forest and obey the fire protocols in the forest
For the answer to the question above,
An area where soil has eroded experience <u>"</u><u>loss of nutrients. "</u>
The topmost layer of soil is called the topsoil and is the most fertile. Soil erosion results in the loss of soil fertility and makes the land barren
The main cause of soil erosion is the removal of vegetation, which exposes the topsoil to water and wind. Wind and water are the main agents of soil erosion.
Water erosion can be sheet erosion, rill erosion, gully erosion or riparian erosion.
