<span>Rattlesnakes would eat a prairie dog if they could catch it. However, if a rattlesnake approached a prairie dog colony, the prairie dog's "sentinels" would alert the rest of them, and they would hide in their holes. A rattlesnake could fit into the holes, but I don't think that snakes usually actively seek prey (they act more like a trap, waiting for prey to come to them). </span>
Answer:
Moreover, the way that this works is that convection currents in the mantle causes tectonic plates to move when material near the Earth's core rises, and colder mantle rock sinks. Hot magma wells up at the ridges, forming new ocean crust and shoving the plates apart.

Answer:
C.
Gentoo penguins eat more types of prey than either Adélie or Chinstrap penguins.
Explanation: It makes the most sense over the other ones.
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.

Answer:
A) Registers manufacturers and prescribers of controlled substances.
Explanation:
The U. S. Drug Enforcement Administration is a United States federal law enforcement agency under the United States Department of Justice. Their role is to Registers manufacturers and prescribers of controlled substances.
Their long-term goal of the U. S. Drug Enforcement Administration is to impose the controlled substances laws and regulations and bring to justice the criminal act of the United States, in order to achieve these measures, they registers manufacturers and prescribers of controlled substances.
