Answer:
The correct order would be:
A vaccine introduces a weakened flu virus into the body.
↓
The immune system identifies antigens on the weakened flu virus.
↓
Antibodies are produced, which bind to the weakened flu virus and signal immune cells to destroy it.
↓
The actual flu virus enters the body, and lymphocytes recognize the antigens.
↓
Antibodies are quickly produced and allow the body to fight off the infection.
Vaccination or immunization is the process which helps in developing the immunity (adaptive) against a particular pathogen or microorganism.
It includes the administration of antigen, weakened or heat-killed microorganism (such as flu virus) into the patients body. Body's immune system produces naive B and T cells to eliminate the antigen.
This encounter enables the immune system to produce memory B and T cells against that particular pathogen.
In future, whenever the same antigen enters the body, the immune system gets activated quickly due to the presence of memory cells. It enables the body to produce more effective secondary response against the pathogen.
O'Brien mentions that Winston writes Newspeak elegantly. He also alludes to Winston's comrade, Syme.
When taken out of the freezer and placed on a piece of foil, 2 pieces of ice will melt at the same rate because the piece of foil is at room temperature and so are the pieces of ice.
That's the best way that I can explain it :)
In this
case, when Alicia is being tickled by her older sister, the divisions of
the nervous system which are responsible for receiving the signals from her
sister’s fingers are called somatosensory cortex and anterior
cingulated cortex nervous system.
When you are touched lightly, the effect of having that ticklish
sensation is caused by the analysis of two regions of the brain. For example,
when our brain analyses the pressure of the touch, this is the work of
the somatosensory cortex. On the other hand, as
soon as something touches your skin, the signal sent from the skin's sensory
receptors also passes through the anterior cingulated cortex.<span>This is
where the pleasant feelings are governed. </span>
Answer:
Part A: Influenza virus
Part B: Influenza is a public health issue because it is one of the leading cause of death all over the world. Proper vaccination against the illness can prevent death and other serious illness due to this virus.
Part C: serious illness and death, mainly among children and elderly
Part D: Efforts are underway to create a cheap and effective vaccine against this virus. The National Vaccine Program Office is responsible for coordinating and ensuring collaboration among federal agencies involved in vaccine and immunization activities.
Part E: A vaccine against this virus will prevent people from facing the effects of this virus. Also, compulsorily vaccinations against this virus will ensure a major reduction in deaths caused by it.
