Answer:
HIV/AIDS
Explanation:
Autoimmunity is the failure in a functional division of the immune system called self-tolerance, which results in immune responses against the body's own cells and tissues. Any disease that results from this type of response is called autoimmune disease. Examples of autoimmune diseases include rheumatic fever, systemic lupus erythematosus and diabetes mellitus.
HIV/AIDS is not an autoimmune disease, ie it is not related to autoimmunity.
AIDS, or Acquired Immunodeficiency Syndrome, is an infectious disease caused by the HIV (Human Immunodeficiency Virus), which leads to progressive loss of immunity. The disease - actually a syndrome - is characterized by a set of signs and symptoms resulting from the drop in the rate of CD4 lymphocytes, very important cells in the body's immune defense. The more the disease progresses, the more the immune system is compromised and, consequently, the carrier's ability to defend itself against infections.

Answer:
located... on the plasma membrane
is considered... inactive
the messenger is considered... to be active
All of this is brought on by a.... signal molecule
will shut down quickly when the.... signal molecule
Explanation:
The G protein-coupled receptors (GPCRs) are transmembrane proteins found on the plasma membrane. GPCRs are considered to be the most diverse group of transmembrane receptors in eukaryotic cells. These proteins (GPCRs) bind to signaling molecules to trigger signaling pathways through Guanine nucleotide-binding proteins (G-proteins). G proteins are signaling proteins (for example, Ras protein) that bind both GTP and GDP. After the signaling molecule binds to GPCR, GTP is hydrolyzed by the G-protein in a process that triggers specific signaling pathways (for example, activation of the production of second messengers).
The process is called homeostasis.
