<span>This person is experiencing common physical symptoms of what is called "withdrawals". Opiates, when used illegally, can be highly addictive. This drug targets the central nervous system (the brain, cardiovascular and respiratory systems) and contains opioid receptors that receive opiate drugs. Abusing this drug can disrupt a person's brain chemistry, leading to severe physical withdrawal symptoms as listed in the question.</span>
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.
Explanation:
<span>#1) What are saber teeth for these organisms?
Answer: After reading the statements presented above you can conclude that the saber teeth are Analogous structures for these organisms. The reason being that they can be considered as similar features. This usually happens when different organisms live in similar environments, they evolve in a similar way.
