<h2>Immunity </h2>

Explanation:

Immunological memory of adaptive immunity ensures that vaccination effectively prevents disease

When the adaptive immune system is exposed to a new threat, the specifics of the antigen are memorized so we are prevented from getting the disease again
The concept of immune memory is due to the body’s ability to make antibodies against different pathogens
A vaccination against a virus can be made using either active, but weakened or attenuated virus, or using specific parts of the virus that are not active
Both attenuated whole virus and virus particles cannot actually cause an active infection, they mimic the presence of an active virus in order to cause an immune response, even though there are no real threats present
By getting a vaccination, one is exposing the body to the antigen required to produce antibodies specific to that virus, and acquire a memory of the virus, without experiencing illness

A person shakes up vinegar and oil dressing before pouring it on salads. what is the chemical reason for doing this

jasenka [17]

The vinegar is a charged molecule, whereas, the oil is neutral. As like dissolves like, the vinegar can be dissolved with charged molecules and the oil can be dissolved with neutrals. So, to mix vinegar and oil shaking is required.

In case, the person does not mix oil and vinegar dressing before pouring this on the salad, it would not produce a good taste, as the content of vinegar and the oil would not be appropriate.

The nurse should include in their discharge notes to the couple the different ways they may access to guarantee birth control.
They may continue to use barrier methods which are the most safe when it comes to not disturbing any hormonal balance or intervening with the milk. Condoms for men are usually the most easily accessed to.
Besides the barrier methods, there are also the hormonal methods. When breastfeeding these are not the most used methods. There is a special pill, progestin-only pill, that is the most appropriate because it doesn't affect milk supply when taken after 6 to 8 weeks after the birth. All hormonal methods should be taken always when counselled with the doctors.
