Memory b cells provide long term immunity for a specific disease or antigen. As an example a vaccination for hepatitis A provides memory b cells that will attack the disease when it is present and remove it.

In what two ways can a person become immune to an infectious disease?
A person can become immune to an infectious disease through vaccination, which triggers the body's immune response to produce antibodies against the pathogen. Additionally, a person can also develop natural immunity by recovering from an infection, where the immune system creates memory cells that can recognize and fight the pathogen if re-exposed.
How long do auditory images remain in sensory memory?
Auditory images typically last for a few seconds to up to 4-5 seconds in sensory memory. However, this can vary depending on individual factors like attention and the complexity of the sound.
Does memory increase or decrease with age?
Memory decreases with age. When someone is in their twenties the brain starts to lose brain cells. The chemicals the brain needs to function properly are made, but not as abundant as they were when a person was younger.
What is the positive color of silver nitrate?
When testing silver nitrate, a whitish color will yield positive results. If the test is negative, the color will turn clear and it will remain transparent.
Why is it adaptive for memory cells to remain in the immune system after an invasion by pathogens?
Memory cells provide faster and stronger immune response upon re-exposure to the same pathogen, aiding in quicker elimination of the threat. This mechanism improves overall immune system efficiency and provides long-term protection against recurrent infections.
Why does passive immunity last long?
Passive immunity lasts longer because it involves the transfer of antibodies from one individual to another, providing immediate protection without the need for the recipient's immune system to produce its own antibodies. These antibodies can remain in the bloodstream for weeks to months, depending on their type and the individual's metabolism. However, since passive immunity does not stimulate the recipient's immune system to create a memory response, it does not provide long-term immunity like active immunity. Thus, while passive immunity offers short-term protection, its duration can still be significant compared to other forms of immediate defense.
Which part of the immune system can most effectively eliminate influenza virus that has infected body cells?
We call this type of immunity adaptive---> natural----> active immunity. Here how it works: Adaptive immunity involves two classes of lymphocyte: B cells and T cells which work together in a coordinated system of adaptive immunity B cells-antibody-mediated (humoral) immunity T cells-cell-mediated (cellular) immunity Adaptive immunity occurs in a series of stages 1. Recognition of antigen (flu virus) 2. Activation of lymphocytes 3. Effector phase (immune attack) 4. Decline of antigen causes lymphocyte death (homeostatic balance) 5. Memory cells remain for later response if needed
What is Intel Flex Memory Access?
Intel® Flex Memory Access facilitates easier upgrades by allowing different memory sizes to be populated and remain in dual-channel mode.
What is the meanig of remember?
To retain in the memory, to remain aware of and to bring to mind when the information is required

When stimulated B cells differentiate into?
When stimulated, B cells differentiate into plasma cells and memory B cells. Plasma cells are responsible for producing and secreting antibodies specific to the antigen that triggered the immune response. Memory B cells remain in the body long-term, providing a quicker and more robust response if the same antigen is encountered again in the future. This differentiation is crucial for the adaptive immune response and long-term immunity.
Anitgen-sensitized cells that remain in circulation for long periods of time?
Memory B cells and memory T cells are antigen-sensitized cells that can remain in circulation for long periods of time. These cells are part of the adaptive immune response and provide immunological memory, allowing for a faster and more effective response upon re-exposure to the same antigen.
How do you use physical evidence in a sentence?
A witnesses' memory can change but the physical evidencewill remain the same.
What was the memory storage like in the original computers?
our brain but we will take some time to remain the things
What characteristics of read-only memory (ROM) make it useful?
Once Read Only Memory is initialized and set, its contents remain unchanged even when there is a loss of power.
How is a memory-resident part of an operating system different from a nonresident part of an system?
A memory-resident part of an operating system is continuously loaded into the computer's memory and ready for immediate use, enabling faster access and better system performance. On the other hand, a nonresident part is stored on the disk and is only loaded into memory when needed, causing delays in accessing the functionality.
How many people have fibromyalgia in the world?
5 percent of the world's population has fibromyalgia and millions of people remain undiagnosed.
