How is the heat in metabolism useful to a cell?
It can help speed up reactions, such as when your body heats up when you are sick in order to speed up its immune response. It can also help regulate temperature if the cell is in a colder environment.

Can you still get Swine Flu after the vaccine?
Absolutely, the vaccine simply builds up your immune system - one can still become infected.
Do you need swine flu vaccine more than once?
It won't usually hurt to receive it more than once, but it won't be necessary to repeat it unless you are 6 months old up to 9 years old, and then you will need an initial vaccination followed by a booster (about a month later) since your immune system is not fully mature to give a good immune response from a single exposure to the vaccine at those younger ages.
What does a vaccine contain that allows the body to do this?
The theory behind the vaccine is that it is made up of weakened viruses but that form antibodies, which in turn build up the immune system that will fight the introduction of any pathogen the vaccine is intended to prevent.
What 4 body functions speed up and slow down during the alarm Stage?
During the alarm stage of the stress response, heart rate, respiration rate, blood pressure, and adrenaline production speed up. Meanwhile, digestion, immune response, and reproductive functions may slow down as the body prepares for fight or flight.
How does a vaccine produce its effects?
Dead virus cells are injected causing the animal's body's immune system to build up immunity to that particular virus. When the animal comes across that same virus it already has immunity built up so the chance of 'getting' that same germ is greatly reduced. This is an over-simplified explanation but it will give you an idea of how it works.
What is made up of dead or weakened virus or virus particles?
Vaccines are made up of dead or weakened virus particles to stimulate the immune system to produce an immune response without causing illness.
What are examples of specific immunity?
antiserum
How does penicillin trigger an immune response?
Penicillin can bind to proteins in the body, forming a complex that the immune system recognizes as foreign. This can trigger an immune response by activating immune cells like T lymphocytes and causing the release of inflammatory molecules. In some individuals, this immune response can lead to penicillin allergy or hypersensitivity reactions.
What does yellow fever vaccine contain?
Yellow fever is caused by a virus that is spread by the female mosquito. The vaccine for yellow fever has been used commercially since the 1950's and one dose provides life-long vaccination against yellow fever.
What does it mean when rubella screen comes up not immune?
This means the person has had rubella (German measles ) or a vaccination for rubella in the past and so is now immune. This test is often part of checks before pregnancy so that a vaccine can be given if it negative before a woman becomes pregnant. The vaccine is usually the MMR (which also immunises for mumps and measles). Single vaccine rubella is no longer licenced in the UK.
