What happens in your body to cause you to get a fever?

Biology

The presence of a fever is usually related to stimulation of the body's immune response. Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive. Infectious agents are not the only causes of fever, however. Amphetamine abuse and alcohol withdrawal can both elicit high temperatures, for example. And environmental fevers--such as those associated with heat stroke and related illnesses--can also occur.

The hypothalamus, which sits at the base of the brain, acts as the body's thermostat. It is triggered by floating biochemical substances called pyrogens, which flow from sites where the immune system has identified potential trouble to the hypothalamus via the bloodstream. Some pyrogens are produced by body tissue; many pathogens also produce pyrogens. When the hypothalamus detects them, it tells the body to generate and retain more heat, thus producing a fever. Children typically get higher and quicker fevers, reflecting the effects of the pyrogens upon an inexperienced immune system.

What term is used to describe 100’s or 1000’s of amino acids chemically combined?
hjlf

Answer:

Polypeptide

Explanation:

Amino acids are the building block and simplest unit of protein molecules. The structural composition of each amino acids is made up of an amine group (-NH2), a carboxylic acid group (-COOH), a hydrogen atom (H) and a R side chain that differentiates every amino acid from one another.

In a reaction process called condensation, amino acids are chemically joined together via the amine group of one and the carboxylic group of another. This process releases water molecule (H20) to form a bond called PEPTIDE bond between the amino acids. Several amino acids in their 100’s or 1000’s that are chemically joined this way forms a POLYPEPTIDE chain, which in turn forms the protein molecule.

How is carbon<br> exchanged between<br> living and the<br> nonliving parts of the<br> environment?
Ede4ka [16]

Answer:

Carbon dioxide from the air is used to produce food for plant growth. Carbon moves from plants to animals when animals eat the plants. Also, Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere.

The burning of fossil fuels also releases carbon dioxide into the atmosphere.

Explain how super-antigens, such as toxic shock syndrome toxin produced by staphylococcus aureus, often lead to the development
GaryK [48]

Toxic shock syndrome toxin is a super-antigen produced by Staphylococcus aureus bacteria .it causes toxic shock syndrome by stimulating the release of large amount of interleukin-1, interleukin-2 and tumor necrosis factor .

Interleukin-1:

It is a group of 11 cytokines that plays a central role in the regulation of immune and inflammatory responses to infections .

Interleukin-2:

It is a type of cytokine signaling molecule in the immune system .interleukin-2 is apart of the body's natural response to microbial infection and in discriminating self and non self foreign.

tumor necrosis factor :

Tumor necrosis factor is protein superfamily  of type 2 transmembrane protein  containing  tnf homology domain and trimers .these proteins are expressed predominantly by immune cells and they regulate diverse cell functions ,including immune response and inflammation ,but also proliferation, differentiation and embryogenesis.

Staphylococcus aureus:

Staphylococcus aureus is a gram positive pathogen cable of producing a variety of bacterial exotoxin known as super antigens .

Toxic shock syndrome :

Toxic shock syndrome is an acute disease mediated by the production of super-antigenic toxin .it is rare , life threatening complication of certain type of bacterial  infections. often it results from toxins produced by staphylococcus aureus bacteria but the condition may also be caused by toxins produced by group a streptococcus bacteria.

Toxic shock syndrome can affect anyone ,including men , older woman, children and postmenopausal women.risk factors of toxic shock syndrome includes skin wounds ,surgery ,and use of tampons and devices such as menstrual cups contraceptive devices ,etc.

Symptoms of toxic shock syndrome toxin:

A sudden high fever,low blood pressure ,vomiting or diarrhea ,rash resembling sunburn ,muscle aches ,redness of eyes ,mouth and throat ,headache and seizures.

Conclusion:

If you have these symptoms of toxic shock syndrome then immediately call your doctor or consult a doctor and take precautions.
