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.

Hello!
The sentence that best describes what Colton discovers is D) The mass of the melted ice cube remained the same at 4 grams.
<h2>Why?</h2>
The melting of the ice cube is a physical process. That means that it is a process in which the identity of the substance (water) doesn't change, but only how their molecules are arranged.
In melting, a substance in the solid state changes to the liquid state. Its molecules go from having a definite volume and shape to having the same shape as the container that holds it, but there are no changes in the mass of the substance.
If the container is closed, Colton should record the same mass as the initial one, as mass doesn't change in physical processes.
Have a nice day!
